[ARROW-2067] [Python] "pip install" doesn't work from source tree

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Won't Fix
• Affects Version/s: 0.8.0
• Component/s: Python
• External issue URL: https://github.com/apache/arrow/issues/18044
• Assignee: Antoine Pitrou

Description

It seems that pip install . first copies the build dir into a temporary directory, and setuptools_scm then fails grabbing the git version from that location.

AFAIR versioneer doesn't have that issue.

$ pip install .

    Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
    
    For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj
