      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
