ImportError: No module named gi.repository #2

Closed ExcaliburZero closed 9 years ago

ExcaliburZero commented 9 years ago

The following errors are currently showing up in Travis CI. Python seems unable to import gi.repository.

This seems to be an issue with the gi module of Python not being installed. This module seems to be related to the GObject and Gtk modules.

It seems that PyGObject needs to be installed via Pip.

The following repository's Travis CI config seems to be able to solve this problem:

It seems that this commit in another repository was able to fix this same error:

It looks like the issue is that apt-get can be used to install Python dependencies but they are not noticed by Travis CI unless the following code is in the config file.

virtualenv:
  system_site_packages: true

See: http://danielnouri.org/notes/2012/11/23/use-apt-get-to-install-python-dependencies-for-travis-ci/

I think the issue has now been fixed. I just need to rebase and squash the commits and then I can work on the next error.

However this seems to have caused another problem which causes Python versions 2.6, 3.3, 3.4, and nightly to not even get to the install process.

Example (Python 3.3):

$ source ~/virtualenv/python3.3_with_system_site_packages/bin/activate
/home/travis/build.sh: line 41: /home/travis/virtualenv/python3.3_with_system_site_packages/bin/activate: No such file or directory
The command "source ~/virtualenv/python3.3_with_system_site_packages/bin/activate" failed and exited with 1 during .

I attempted to add sudo: required to the Travis CI config in attempt to fix the problems, however that didn't work.

According to the user dstufft in the Travis CI issue 2231, a solution like the following could work:

$ sudo add-apt-repository -y ppa:fkrull/deadsnakes
$ sudo apt-get -y update
$ sudo apt-get install python3.3 python3.3-dev
$ virtualenv -p /usr/bin/python3.3 ~/virtualenvs/3.3_debian
$ source ~/virtualenvs/3.3_debian/bin/activate

I tried implementing dsufft's solution, but I have not gotten it to work yet.

After doing so more tests I decided to revert to using system_site_packages: true to allow the installation of Python libraries. However, I did have to remove testing for all versions of Python except 3.2 and 2.7, as the others did not allow the use of this method.
