-----------------------------------
Summary: [Python] test_get_library_dirs_win32 fails if libraries
installed someplace different from conda or wheel packages
Key: ARROW-4074
URL: https://issues.apache.org/jira/browse/ARROW-4074
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Wes McKinney
Fix For: 0.12.0
Following the development instructions in docs/source/python/development.rst I
get the following error:
{code}
@pytest.mark.skipif('sys.platform != "win32"')
def test_get_library_dirs_win32():
library_dirs = pa.get_library_dirs()
library_lib = library_dirs[-1]
> assert os.path.exists(os.path.join(library_lib, 'arrow.lib'))

I have the libraries in {{C:\thirdparty\lib}}, and ARROW_HOME is set to
{{C:\thirdparty}} per the instructions. Maybe we can add the ARROW_HOME env
variably if set to the candidate directories
