Rok Mihevc updated ARROW-5210:
------------------------------
External issue URL: https://github.com/apache/arrow/issues/21685
> [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
> Priority: Minor
>
> 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:
> {code:none}
>
> -- Looking for python3.7m
> -- Found Python lib
> /home/joris/miniconda3/envs/arrow-dev/lib/libpython3.7m.so
> CMake Error at cmake_modules/FindNumPy.cmake:62 (message):
> NumPy import failure:
> Traceback (most recent call last):
> File "<string>", line 1, in <module>
> ModuleNotFoundError: No module named 'numpy'
> Call Stack (most recent call first):
> CMakeLists.txt:186 (find_package)
> -- Configuring incomplete, errors occurred!

> error: command 'cmake' failed with exit status 1
> Cleaning up...
> {code}
>
> Alternatively, doing {{python setup.py develop}} to achieve the same still
> works.
