DLL not found on Conda Windows

[polm]

The alpha 1.0 release work on Windows, but there was a report of it not working in conda on Win10. The binary wheel seems to be installed correctly and fugashi works so it's unclear what the cause is.

To install the alpha, run pip install mecab-python3==1.0.0a1. To test it, fire up python and import MeCab. If that works you should be OK.

The full release is out now. I set up a Windows dev environment and tested it and I'm not sure if I can reproduce it reliably. First I opened an "Anaconda prompt" somehow, installed mecab-python3, and got the same error as was reported:

>>> import MeCab
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\23\anaconda3\lib\site-packages\MeCab\__init__.py", line 10, in <module>
    from . import _MeCab
ImportError: DLL load failed: 指定されたモジュールが見つかりません。

Then I tried Powershell and virtualenv with standard Python (not Anaconda). That had no issues.

Then I tried Anaconda and Powershell. That also worked fine, so I wondered if I was imagining things.

Next I tried Anaconda and command.exe. I thought this was the same as the "Anaconda prompt" but apparently not. In any case this also works.

I guess this needs more investigation...

OK, I figured out what's going on. After I installed normal Python it updated my paths, and that made Anaconda work. If I have just Anaconda installed or remove the normal Python paths then I get the DLL load failed error. I'll try to see what's causing this.

I'm still having trouble reproducing this, so closing it for now. If you experience this issue please feel free to reopen it.
