Hi,

you just need to:

pip install pygments

on your system, but beware to use the right pip program corresponding to the python version you're using. In this way web2py's book application will be able to use it ;-)

I feel like I'm about to ask a very ironic question but I need to know so here goes; So my web2py is running python Python 2.7.16 but my system is running Python 3.8.3 so is its pip (Python 3.8.3) by installing Pygments with pip for python 3 will it be able to be detected by my web2pywhich is  running Python 2.7.16 or are there gonna be compatibility issues? Coz right now I have installed Pygments on my laptopn but i'm still getting the same error!

Hi,

I'm also using Python 2 and 3 in parallel. I'm not using Pygments but other pipped libraries. And I'm using pip for the Python2 version and pip3 for Python3 version. Having installed both versions I'm just running Python 2 or 3 and the right library is linked.

Furthermore I'm using update-alternatives (Ubuntu/Linux) to switch between Python2 and 3, especially for testing that both versions are served by my web2py app.

Hope, I could help!

[Nico Zanferrari]

No,

 

this is a bad idea, don't try it. Instead, let the right version of Python use its own pip version; in your case:

python2.7 -m pip install pygments

should work fine. See here for details.
