No module named gi about pympress HOT 6 CLOSED

Maybe the workflow described in this Stackoverflow question allows you to use the gi module from your Anaconda installation.

from pympress.

If you installed python3-gi you really should have the gi module.

It seems that you are using a python version inside an installation of anaconda. You should you have a different python installation, and you probably installed gi for one and pympress for the other. In that case, try forcing the python outside the anaconda installation (for example in the default location, it could be /usr/bin/python3:

pip uninstall pympress
/usr/bin/python3 -m pip install pympress
/usr/bin/python3 -m pympress

If that fixes it, you should check what defaults where as python installations go, on your system. Maybe default to using the non-anaconda python, or install gi for the anaconda python.

To make the above fix more definitive, you can modify the pympress entry point (you can find out where it is using which pympress, usually at $HOME/.local/bin/pympress) to make sure it points to the non-anaconda python installation (on the first line, after the initial #!). From there on just running pympress should be fine.

Thank you for the answer, I think we can close this one.

Hi,

I had another problem with the import of cairo, I tried solving it in the same fashion but it didn't work, after a few research it appears that there is no cairo for python2 and so we need to use python3 (which I thought would be done using pympress3) but at the begining of the file in /usr/bin/pympress and /usr/bin/pympress3 we have the following line :
#!/usr/bin/python
changing it to python3 worked for me :
#!/usr/bin/python3

from pympress.

Using apt-cache search python cairo on my Ubuntu system, it says that there is a Cairo package for Python2 (shortened output):

python-cairo - Python bindings for the Cairo vector graphics library
python-cairo-dbg - Python bindings for the Cairo vector graphics library (debug extension)
python-cairo-dev - Python cairo bindings: development files
python3-cairo - Python 3 bindings for the Cairo vector graphics library
python3-cairo-dev - Python 3 cairo bindings: development files
python3-cairo-doc - Python 3 cairo bindings: documentation files
python3-gi-cairo - Python 3 Cairo bindings for the GObject library
python-gi-cairo - Python Cairo bindings for the GObject library

Another alternative (instead of modifying the Shebang line of an installed package): Calling python3 -m pympress instead of pympress from the terminal should do the trick to (when doing so, the Shebang line is ignored).

if it works for you we can close this issue, @PierreQuinton.

The moral of the story is to make sure the same python installation if used for pympress as well as for all its dependencies.
