Posted: (6 days ago) Aug 17, 2016 I read about installing modules is only possible in the command line.

PyQt is often not installed by default. The PyQt module can be used to create desktop applications with Python. In this article you’ll learn how to install the PyQt module.

The steps to install pip3 are simple and easy to follow. Once you have python 3, use the following command to install pip3: sudo apt-get update sudo apt install python3-pip. Python3 get-pip.py. When you run this command, it installs the applications used to build python modules. Download Mac OS X 64-bit/32-bit x86-64/i386 Installer; Python 2.6.9 - Oct. No files for this release. Python 3.3.2 - May 15, 2013.

Desktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi).

$ sudo apt-get update $ sudo apt-get install python3.8 python3-pip Once the installation is complete, you can run Python 3.8 with the python3.8 command and pip with the pip3 command. Linux Mint and Ubuntu 17 and below: Python 3.8 isn’t in the Universe repository, so you need to get it from a Personal Package Archive (PPA). PyQt is often not installed by default. The PyQt module can be used to create desktop applications with Python. In this article you’ll learn how to install the PyQt module. Desktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi). Doing it Right¶. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package.

How to install PyQt5 on Windows?

To install PyQt on Windows there are a few steps you need to take.
First use the installer from the qt-project website, from qt to install PyQt.

Next you want to install a Python version 3.3 or newer. Check the box to add all of the PyQt5 extras. It’s not necessary to compile everything from source, you can install all the required packages with the installer.

On Python >= 3.6, you can also try this command:

It should work without problems.

How to install PyQt5 on Mac OS X?

On Apple Mac OS X installation is a bit simpler. The first step to take is to install the Mac OS X binary. This installs the PyQt GUI library.

But to use it from Python, you also need Python module. This is where the tool brew comes in.
You can use brew to install pyqt (in the terminal):

How to install PyQt5 on Linux?

Python is often installed by default on Linux (in nearly all of the distributions including Ubuntu). But you want to make sure to use Python 3, because of all the features and ease of use. You can verify that you have the newest Python version with the command:

On Ubuntu Linux they sometimes include two versions of python, python3 and python. In that case use Python 3.

Once you have Python ready, the next step is to install PyQt.

This isn’t hard to do if you have some Linux experience. You can install PyQt your software package manager. Which package manager to use depends on which Linux distribution you are using.

On Ubuntu Linux / Debian Linux you can use the command:

For CentOS 7 use the command:

For RPM-based systems (Redhat-based)

If you are new to Python PyQt, then I highly recommend this book.

Mac OS X comes with Python 2.7 out of the box.

You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.

The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.

Doing it Right¶

Let’s install a real version of Python.

Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.

Note

If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.

Note

If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install on the terminal.

While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.

To install Homebrew, open Terminal oryour favorite OS X terminal emulator and run

The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your PATH environment variable. You can do this by adding the followingline at the bottom of your ~/.profile file

If you have OS X 10.12 (Sierra) or older use this line instead

Now, we can install Python 3:

This will take a minute or two.

Pip¶

Homebrew installs pip pointing to the Homebrew’d Python 3 for you.

Working with Python 3¶

At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.

will launch the Homebrew-installed Python 3 interpreter.

will launch the Homebrew-installed Python 2 interpreter (if any).

will launch the Homebrew-installed Python 3 interpreter.

If the Homebrew version of Python 2 is installed then pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then pip will point to Python 3.

The rest of the guide will assume that python references Python 3.

Pipenv & Virtual Environments¶

The next step is to install Pipenv, so you can install dependencies and manage virtual environments.

Pip Install Virtualenv Python3 Mac

A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.

As a popular open source development project, Python has an activesupporting community of contributors and users that also make their softwareavailable for other Python developers to use under open source license terms.

This allows Python users to share and collaborate effectively, benefitingfrom the solutions others have already created to common (and sometimeseven rare!) problems, as well as potentially contributing their ownsolutions to the common pool.

This guide covers the installation part of the process. For a guide tocreating and sharing your own Python projects, refer to thedistribution guide.

Note

For corporate and other institutional users, be aware that manyorganisations have their own policies around using and contributing toopen source software. Please take such policies into account when makinguse of the distribution and installation tools provided with Python.

Key terms¶

  • pip is the preferred installer program. Starting with Python 3.4, itis included by default with the Python binary installers.

  • A virtual environment is a semi-isolated Python environment that allowspackages to be installed for use by a particular application, rather thanbeing installed system wide.

  • venv is the standard tool for creating virtual environments, and hasbeen part of Python since Python 3.3. Starting with Python 3.4, itdefaults to installing pip into all created virtual environments.

  • virtualenv is a third party alternative (and predecessor) tovenv. It allows virtual environments to be used on versions ofPython prior to 3.4, which either don’t provide venv at all, oraren’t able to automatically install pip into created environments.

  • The Python Package Index is a publicrepository of open source licensed packages made available for use byother Python users.

  • the Python Packaging Authority is the group ofdevelopers and documentation authors responsible for the maintenance andevolution of the standard packaging tools and the associated metadata andfile format standards. They maintain a variety of tools, documentation,and issue trackers on both GitHub andBitbucket.

  • distutils is the original build and distribution system first added tothe Python standard library in 1998. While direct use of distutils isbeing phased out, it still laid the foundation for the current packagingand distribution infrastructure, and it not only remains part of thestandard library, but its name lives on in other ways (such as the nameof the mailing list used to coordinate Python packaging standardsdevelopment).

Changed in version 3.5: The use of venv is now recommended for creating virtual environments.

Basic usage¶

The standard packaging tools are all designed to be used from the commandline.

The following command will install the latest version of a module and itsdependencies from the Python Package Index:

Note

For POSIX users (including macOS and Linux users), the examples inthis guide assume the use of a virtual environment.

For Windows users, the examples in this guide assume that the option toadjust the system PATH environment variable was selected when installingPython.

It’s also possible to specify an exact or minimum version directly on thecommand line. When using comparator operators such as >, < or some otherspecial character which get interpreted by shell, the package name and theversion should be enclosed within double quotes:

Normally, if a suitable module is already installed, attempting to installit again will have no effect. Upgrading existing modules must be requestedexplicitly:

More information and resources regarding pip and its capabilities can befound in the Python Packaging User Guide.

Creation of virtual environments is done through the venv module.Installing packages into an active virtual environment uses the commands shownabove.

How do I …?¶

These are quick answers or links for some common tasks.

… install pip in versions of Python prior to Python 3.4?¶

Python only started bundling pip with Python 3.4. For earlier versions,pip needs to be “bootstrapped” as described in the Python PackagingUser Guide.

… install packages just for the current user?¶

Passing the --user option to python-mpipinstall will install apackage just for the current user, rather than for all users of the system.

… install scientific Python packages?¶

A number of scientific Python packages have complex binary dependencies, andaren’t currently easy to install using pip directly. At this point intime, it will often be easier for users to install these packages byother meansrather than attempting to install them with pip.

… work with multiple versions of Python installed in parallel?¶

On Linux, macOS, and other POSIX systems, use the versioned Python commandsin combination with the -m switch to run the appropriate copy ofpip:

Appropriately versioned pip commands may also be available.

On Windows, use the py Python launcher in combination with the -mswitch:

Common installation issues¶

Installing into the system Python on Linux¶

On Linux systems, a Python installation will typically be included as partof the distribution. Installing into this Python installation requiresroot access to the system, and may interfere with the operation of thesystem package manager and other components of the system if a componentis unexpectedly upgraded using pip.

On such systems, it is often better to use a virtual environment or aper-user installation when installing packages with pip.

Pip not installed¶

There are also additional resources for installing pip.

Installing binary extensions¶

Mac Install Python Package

Python has typically relied heavily on source based distribution, with endusers being expected to compile extension modules from source as part ofthe installation process.

With the introduction of support for the binary wheel format, and theability to publish wheels for at least Windows and macOS through thePython Package Index, this problem is expected to diminish over time,as users are more regularly able to install pre-built extensions ratherthan needing to build them themselves.

Some of the solutions for installing scientific softwarethat are not yet available as pre-built wheel files may also help withobtaining other binary extensions without needing to build them locally.
