How To Install wxPython 4 on Ubuntu 18.04

Ubuntu 5

In this comprehensive guide, we will walk you through the process of installing wxPython 4 on Ubuntu 18.04. wxPython is a wrapper for the cross-platform GUI toolkit wxWidgets, which is written in C++. It is a great tool for creating desktop applications in Python.

Quick Answer

To install wxPython 4 on Ubuntu 18.04, you need to install the necessary dependencies using the apt package manager and then use either pip or pip3 to install wxPython. After the installation, you can verify it by running a simple Python script.

Prerequisites

Before we begin, make sure you have the following:

  • A system running Ubuntu 18.04.
  • Sudo privileges to install packages.
  • A stable internet connection.

Step 1: Installing the Necessary Dependencies

wxPython requires a number of dependencies to be installed on your system. These dependencies include development libraries such as libgtk-3-dev, libwebkitgtk-dev, libgstreamer-gl1.0-0, and others. These libraries provide the necessary components for wxPython to interact with the system’s graphical user interface.

Open a terminal and run the following command to install these dependencies:

sudo apt install make gcc libgtk-3-dev libwebkitgtk-dev libwebkitgtk-3.0-dev libgstreamer-gl1.0-0 freeglut3 freeglut3-dev python-gst-1.0 python3-gst-1.0 libglib2.0-dev ubuntu-restricted-extras libgstreamer-plugins-base1.0-dev

This command uses the apt package manager to install the necessary packages. The sudo command is used to run the command with root privileges.

Step 2: Install wxPython

After installing the necessary dependencies, you can install wxPython using either pip or pip3 depending on your Python version.

To install wxPython, run one of the following commands in your terminal:

sudo pip install wxpython

or

sudo pip3 install wxpython

The pip or pip3 command is a package installer for Python. You can use it to install and manage additional packages that are not part of the Python standard library. The sudo command is used to run the command with root privileges.

Step 3: Verify the Installation

After the installation is finished, you can verify the successful installation of wxPython by running a simple Python script that imports the wx module.

Create a new Python file and add the following lines of code:

import wx
print(wx.version())

This script imports the wx module and prints the version of wxPython installed on your system. If the script runs without any errors and prints the version of wxPython, this indicates that wxPython has been successfully installed.

Troubleshooting

If you encounter any errors during the installation, you can try the following alternative solutions:

  • Solution 1: Use the alternative set of dependencies for Ubuntu 20.04:
sudo apt install make gcc libgtk-3-dev libwebkit2gtk-4.0-dev libgstreamer-gl1.0-0 freeglut3 freeglut3-dev python3-gst-1.0 libglib2.0-dev ubuntu-restricted-extras libgstreamer-plugins-base1.0-dev
  • Solution 2: Download the wheel file manually and install it using pip. For example, if you are using Lubuntu 18.04, you can download the wheel file wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl using wget, and then install it with pip3:
wget <URL_TO_WHEEL_FILE>
sudo pip3 install wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl

Conclusion

In this guide, we’ve covered how to install wxPython 4 on Ubuntu 18.04. We’ve also discussed the dependencies required for the installation and provided some troubleshooting tips if you encounter any problems during the installation. With wxPython installed on your system, you can now start developing cross-platform GUI applications in Python. Happy coding!

Can I install wxPython on Ubuntu 20.04 using the same steps?

Yes, you can follow the same steps to install wxPython on Ubuntu 20.04. However, in Step 1, you may need to use an alternative set of dependencies. You can refer to the Troubleshooting section for the alternative dependencies command.

Can I install wxPython on other Linux distributions?

Yes, you can install wxPython on other Linux distributions using similar steps. However, the package manager and package names may differ. You can search for the equivalent packages for your distribution’s package manager and modify the installation commands accordingly.

Can I install wxPython without using `pip`?

Yes, you can install wxPython without using pip by building it from source. However, this process can be more complex and time-consuming. It is recommended to use pip for a simpler installation process.

Can I use wxPython with Python 2?

No, wxPython 4 is only compatible with Python 3. If you are using Python 2, you will need to install an older version of wxPython that supports Python 2.

How can I uninstall wxPython?

To uninstall wxPython, you can use pip or pip3 depending on the Python version you used for installation. Open a terminal and run one of the following commands:

sudo pip uninstall wxpython

or

sudo pip3 uninstall wxpython

This will remove the wxPython package from your system.
