pygments 2.0 & 2.0.1 does not work

[anonymous]

I just updated my pygments from 1.6 to 2.0.1 on my trac 1.0.2 and noticed that syntax highlighting does not work anymore.

Aktivating the log file I can see that the plugin load crashes.

I use:

• win7 64 bit
• python 2.7.8 32 bit

A duplicate of #11796.

Reopening against 1.0.4. I know this was closed as duplicate of #11796, but it does not look to be the same issue.

In Trac 1.0.4 using Pygments 2.0.2 I get the following error log, which is consistent with this ticket's description. Pygments 1.6 works fine.

Environment Win7 x64, 32-bit Python

Package Version
Trac 1.0.4 
Docutils 0.12 
Genshi 0.6 (without speedups)

It seems that you still use Trac 1.0.2.

• See tags/trac-1.0.2/trac/mimeview/pygments.py@:37#L32​
• HtmlFormatter = pygments.formatters.html.HtmlFormatter doesn't exist in tags/trac-1.0.4/trac/mimeview/pygments.py​.

Doing really well here. I got the wrong error log entry.

I do not think that is true. Here is the start of my Trac startup log

2015-03-08 22:37:00,352 Trac[env] INFO: -------------------------------- environment startup [Trac 1.0.4] --------------------------------

I consider you have an InstallationIssue. Installed Trac code in your environment is 1.0.2. Trac's egg-info is only 1.0.4. Otherwise, you probably haven't restarted your web server.

1. Stop your web server
2. Remove lib/site-packages/trac, lib/site-packages/tracopt and lib/site-packages/Trac-*.egg-info
3. Reinstall Trac 1.0.4
4. Start your web server

You are correct. I had stopped the server during upgrade. But, I did not delete all old site-packages prior to install. I did not know it was possible for the log to say one version of Trac, but for the actual running system to be another version. I had assumed the egg was self-contained for core components.

Sorry to reopen a ticket for a site configuration error.
