@nph4 I did some testing, and it turns out this was happening because under the hood, GitPython was trying to check if the system was on windows using the wrong path to uname, as it defaults to the location of the git installation, which in the Docker image I was using was in /usr/bin, but uname is located in /bin, so it was throwing this error. The fix for this is included in #188
