Incompatible module name

[akiotajima]

Hi,

Threre are two issues on 0.8.1. 1) Swig add prefix '_' in front of the module name, Therefore any programs using previous version as 'import MeCab' are failed to load the module. 2) The tar.gz does not include README.rst, threfore Pip failed to install it.

Best regards

I also encoutered the same error as follows.

$ pip install mecab-python3 --no-cache

For a "quick and dirty" fix to this issue, download and extract the source, comment out lines 6, 7 and 22 from setup.py (the lines that reference the README and the long_description) and then install via python setup.py install. It appears to work, since the README.rst file is not needed for the wrapper itself to function.

@jamesh627 @akiotajima thank you for the report. I fixed the error which you encountered (the 2 problem). Would you mind to reinstall again and check does it work or not ?

@SamuraiT Thank you for the fix.

I try to install mecab-python3==0.8.3. Installation succeeded(README.rst problem is solved) but import MeCab is failed.

In [1]: import MeCab

I also tried to python setup.py install, it works. (swig 3.0.8 Compiled with g++ [x86_64-pc-linux-gnu])

I see. Let's dig this problem. but before digging & fixing the problem, I'll delete recent versions. :\

[SamuraiT]

Incompatible module name problem is occurring since we introduced swig. I'm not familiar with swig, but you are @zackw. so I'd like you to help solving this problem if possible. Do you have a any idea to fix this ? @zackw

[zackw]

I'm not going to have time to look at this until next week at the earliest.

[SamuraiT]

Ok, take a look at it after that 👍

[zackw]

I think this is fixed by b37ea31.
