This is a Python wrapper for theMeCab morphological analyzer for Japanesetext. It currently works with Python 3.8 and greater.

Note: If using MacOS Big Sur, you'll need to upgrade pip to version 20.3 orhigher to use wheels due to a pip issue.

Note that Windows wheels require aMicrosoft Visual C++Redistributable, so be sure to install that.

The API formecab-python3 closely follows the API for MeCab itself,even when this makes it not very “Pythonic.” Please consult theofficial MeCabdocumentation for more information.

Binary wheels are available for MacOS X, Linux, and Windows (64bit) areinstalled by default when you usepip:

pip install mecab-python3

These wheels include a copy of the MeCab library, but not a dictionary. Inorder to use MeCab you'll need to install a dictionary.unidic-lite is a goodone to start with:

pip install unidic-lite

To build from source using pip,

pip install --no-binary :all: mecab-python3

In order to use MeCab, you must install a dictionary. There are many different dictionaries available for MeCab. These UniDic packages, which include slight modifications for ease of use, are recommended:

• unidic: The latest full UniDic.
• unidic-lite: A slightly modified UniDic 2.1.2, chosen for its small size.

The dictionaries below are not recommended due to being unmaintained for many years, but they are available for use with legacy applications.

• ipadic
• jumandic

For more details on the differences between dictionaries seehere.

If you get aRuntimeError when you try to run MeCab, here are some things to check:

You have to installthis to use this package on Windows.

Runpip install unidic-lite and confirm that works. If that fixes yourproblem, you either don't have a dictionary installed, or you need to specifyyour dictionary path like this:

tagger = MeCab.Tagger('-r /dev/null -d /usr/local/lib/mecab/dic/mydic')

Note: on Windows, usenul instead of/dev/null. Alternately, if you have amecabrc you can use the path after-r.

If you get this error:

error message: [ifs] no such file or directory: /usr/local/etc/mecabrc

You need to specify amecabrc file. It's OK to specify an empty file, it justhas to exist. You can specify amecabrc with-r. This may be necessary onDebian or Ubuntu, where themecabrc is in/etc/mecabrc.

You can specify an emptymecabrc like this:

tagger = MeCab.Tagger('-r/dev/null -d/home/hoge/mydic')

Chasen output is not a built-in feature of MeCab, you must specify it in yourdicrc ormecabrc. Notably, Unidic does not include Chasen output format.Please seethe MeCab documentation.
