What's wrong

I installed gajim and from Debian's jessie-backports. Now I cannot activate the plugin, because it claims in the plugin dialog that the setuptools package is missing:

Warning: You are missing the Setuptools package.

However python-setuptools is certainly installed:

$ apt-cache show python-setuptools 
Package: python-setuptools
Version: 20.10.1-1.1~bpo8+1

I also tried to install this plugin via the internal plugin downloader of gajim, but the result is the same.

could you try to type this into a python console

__import__('pkg_resources')

lovetox commented 7 years ago

try installing python-pkg-resources

rugk commented 7 years ago

The latter is already installed:

Package: python-pkg-resources
Source: python-setuptools
Version: 20.10.1-1.1~bpo8+1

could you try to type this into a python console

I can do, but after starting gajim from the Python console via os.system, the error still happens.

lovetox commented 7 years ago

no dont start gajim, just tell me what error you get if you type that into the console

__import__('pkg_resources')

Gajim, is a Python2 application, please make sure that the package is also installed for python2

However, as shown above python-setuptools (& python3-setuptools) is installed.

Also this fails:

(whereas easy_install3 works)

In /usr/lib/pymodules/python2.7/rpl-1.5.5.egg-info there is just:

Metadata-Version: 1.0

Actually the special character there caused the issue. After editing the file and removing this char, everything worked. :smiley: Thanks for your help.

lovetox commented 7 years ago
