Antoine Pitrou created ARROW-2067:
-------------------------------------
Summary: "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
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 .

LookupError: setuptools-scm was unable to detect version for

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
