[Error] TravisCI error when trying to import and use GitPython

[GlenNicholls]

I have been trying to find the root directory of a git repository using a manual method (subprocess.Popen) along with GitPython. In both cases, they work on my Windows machine but cause errors on TravisCi POSIX builds noted in this link. For reference, here is my .travis.yml:

os: linux

language: python

sudo: required
services:
  - docker

install:
  - pip install -r requirements.txt

script:
  - git version
  - git rev-parse --show-toplevel
  - "./docker_runall.sh"

Here is the code I am using to use this module:

import git

def get_git_root():
    repo = git.Repo('.', search_parent_directories=True)
    return repo.working_tree_dir

root = get_git_root() + '/'

And my requirements.txt is just grabbing subprocess32 and GitPython. When my build runs my Python scripts, it fails with the below (which can also be seen in the stack overflow link I provided):

As the above shows, GitPython is successfully installed and should be seen by Python, but it is not for some reason. I feel like this should be an easy task, but is proving to be much more difficult than I anticipated to debug.

It would be helpful if you can link to the docker_runall.sh script

[GlenNicholls]

@stsewd Here is the docker_runall.sh script. All it is doing is setting up the VUnit framework in docker, and finding/running all my run.py scripts which fail with the code shown above:

#!/bin/sh

cd $(dirname $0)

if [ -d "vunit_out" ]; then rm -rf vunit_out; fi

docker run --rm -t \
  -v /$(pwd)://work \
  -w //work \
  ghdl/ext:vunit-master sh -c ' \
    VUNIT_SIMULATOR=ghdl; \
    for f in $(find ./ -name 'run.py'); do python3 $f -v; done \
  '

I think this issue can be closed as it was ultimately user error! I realized that the docker image I was using did not have git which was causing the errors I posted above. I am new to Travis and docker, so it took me a while to figure out how to determine where my test was breaking.
