> [Python] "pip install" doesn't work from source tree
> ----------------------------------------------------
>
> Key: ARROW-2067
> URL: https://issues.apache.org/jira/browse/ARROW-2067
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.8.0
> Reporter: Antoine Pitrou
> Assignee: Antoine Pitrou
> Priority: Major
>
> 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.
> {code:bash}
> $ 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
