cannot import pyarrow with PythonCall

[tbeason]

Affects: PythonCall

Describe the bug

Cannot import pyarrow using PythonCall.jl

In a fresh environment / new folder:

using Pkg
Pkg.activate(".")
Pkg.add("CondaPkg")

using CondaPkg
CondaPkg.add("pyarrow")

Pkg.add("PythonCall")
using PythonCall
pyarrow = pyimport("pyarrow")

Result:

julia> pyarrow = pyimport("pyarrow")
ERROR: Python: ImportError: DLL load failed while importing lib: The specified procedure could not be found.

FWIW, it worked about a month or two ago?

I should add that I've gotten it to work fine on a Linux computer, so this could be Windows-specific or could be related to my system somehow. But I'm not using any system installations of anything.

[tbeason]

Hmm.. not sure what is happening. Tried it on my Windows laptop -- failed with installation via conda add, but worked instead with conda pip_add...

Recently updated my desktop to Windows 11, so that could be the issue. I'm starting to think the problem lies with pyarrow itself, but not certain because I can open python and import pyarrow with no issues.

If you open Julia in a setup where importing pyarrow fails, then do pkg> conda run python to open Python and import pyarrow there, does it work? (This checks the package is ok in the exact same Python environment).
