Joris Van den Bossche created ARROW-5210:
--------------------------------------------
Summary: [Python] editable install (pip install -e .) is failing
Key: ARROW-5210
URL: https://issues.apache.org/jira/browse/ARROW-5210
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Joris Van den Bossche
Following the python development documentation on building arrow and pyarrow
([https://arrow.apache.org/docs/developers/python.html#build-and-test),]
building pyarrow inplace with {{python setup.py build_ext --inplace}} works
fine.
But if you want to also install this inplace version in the current python
environment (editable install / development install) using pip ({{pip install
-e .}}), this fails during the {{built_ext}} / cmake phase:

Alternatively, doing `python setup.py develop` to achieve the same does work.
