How to install wxpython 4 ubuntu 18.04

After waiting long enough the process was complete and I got wxPython 4 installed.

• run

  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
  

• sudo pip install wxpython or sudo pip3 install wxpython

• wait for a while for it to install

after completion, you will see this message.

The directory '/home/user-ii-6/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Since there are various options for distro and wx port (GTK2 or GTK3) then the files can not all be located in the same folder for easy access by pip. This simply just means that you'll need to drill down a little further to find the URL to give to pip. For example, to get the GTK3 wxPython builds for Ubuntu 18.04 (and 16.10, LinuxMint 18, and probably others) you can use a pip command like this:

pip install -U \ -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-18.04 \ wxPython

Of course you can always download the wheel file yourself and then use pip to install your local copy of the file.

First I found it by:

sudo apt search python3-wx

I installed the latest wxpython with:

sudo apt-get install python3-wxgtk4.0 python3-wxgtk-webview4.0 python3-wxgtk-media4.0

You may also try synaptic to install it that way if you prefer.
