Can't create new environment with Sqlite

[anmar.abdelaziz@…]

After installing Trac 1.0 I wanted to create new environment but I get this error instead. I'm not sure if it's installation error or Trac error.

Initenv for 'c:\Sharq\Trac' failed.
Failed to create environment.

That is the setuptools 0.7.5 issue. Try to downgrade 0.7.4 or 0.6.45 0.6.46. See ​https://bitbucket.org/pypa/setuptools/issue/28/attributeerror-for-_warn_unsafe_extraction.

Thanks, it was setuptools that caused the issue. This should be mentioned in the installation guide.

​The issue has been fixed and ​pypi:setuptools 0.7.6 is released now.
