即使安装了Python，也找不到PyGObject / gi

Question

I have trouble setting up the Python-Path for it, I don't really know what to do here. I use elementary OS, which should be similar enough to Ubuntu.

My code so far is this:

#!/usr/bin/python3
import gi
gi.require_version('GTK', '3.0')

When I run the script, the system reports that there is no module named "gi". However, when I try

sudo apt-get python3-gi

I get told that it is installed already. I tried

print(sys.path)

and

locate python3-gi

which gave me back some directories. But there were too many, so I don't know what, if this is at all the right way, to to copy where.

Addendum:

Okay, so doing type export PATH="$PATH:/usr/local/bin/python-gi3" yields export is a shell builtin bash: type: PATH=/home/ge0rg/anaconda3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/bin/python3-gi: not found

uname -r yields 3.19.0-51-generic .

In the meantime, I also tried reinstalling python3-gi, to no avail. Also, since python3-gi seems to b located in /usr/lib/python3/dist-pacakges , I tried going into python and doing sys.path.append("/usr/lib/python3/dist-pacakges") where the above mentioned folder was not included before. However, after doing this import gi gives the same error as before: >>> import gi Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named 'gi'

EDIT: Also, locate python3-gi yields:

/var/lib/dpkg/info/python3-gi.prerm
/var/lib/dpkg/info/python3-gi.shlibs`

however, /usr/lib/dist-packages/gi also exists, but locate gi just gives back a whole array of mostly unrelated results.

I am guessing its installed in /usr/local/bin/python-gi3 . If you see it there, open your shell and type type export PATH="$PATH:/usr/local/bin/python-gi3" to set the path
