Getting error while running ride.py

[Sharmarahul09]

on ubuntu 16.04.6 LTS, I installed a robot framework and ride. the installation was with no error. but when I launch ryde.py, the RIDE 's GUI is not open and the ERROR MESSAGE below is displaying on the screen. And I have installed Ride first then wxpython (By mistake)

the configuration is: ubuntu 16.04.6 LTS

python --version Python 2.7.12 robot --version Robot Framework 3.1.2 (Python 2.7.12 on linux2) *pip list robotframework 3.1.2
robotframework-ride 1.7.4.1
robotframework-selenium2library 3.0.0
robotframework-seleniumlibrary 4.3.0

*sudo aptitude search python-wxgtk2.8 i python-wxgtk2.8 - wxWidgets Cross-platform C++ GUI toolkit (wxPython binding)
p python-wxgtk2.8:i386 - wxWidgets Cross-platform C++ GUI toolkit (wxPython binding)
p python-wxgtk2.8-dbg - wxWidgets Cross-platform C++ GUI toolkit (wxPython binding, debug version)
p python-wxgtk2.8-dbg:i386 - wxWidgets Cross-platform C++ GUI toolkit (wxPython binding, debug version)

*sudo aptitude search python-wxversion i A python-wxversion - API for selecting the wxPython version to use

This is the error message i recieve after running ride.py

@Sharmarahul09 First, try to uninstall Pygments, and then see if RIDE starts. If success you have to install a version of Pygments that would work on your python 2.7.

Also, the wxPython version should be updated, download or install from wxpython.org.

I'm not able to uninstall Pygments tried to find in the dpkg --list ,still not successful How to uninstall Pygments?

Pygments, like the other libraries RIDE uses are installed with pip . I would try to update pygments to the version 2.5.2:

sudo -H pip install -U --force pygments==2.5.2

Had the same issue, fixed with the version of pygment 2.5.2.
