Hi!

The issue with MeCab parser says it all: MeCab is not detected, you need to install it separately. Don't forget to install it inside your Docker container 😉

You should be able to use LWT for Japanese only with regular expressions with the results are not so good. What is the error message?

Hope that helps you!

Hi, thanks for your swift reply.

I re-bulit container again without MeCab. It was the same error when I chose regular expressions but MeCab.

Now the texts of Japanese with MeCab and regular expressions works after installation. 🙂

Could one installation solve two problems?

[99MengXin]

I found 2 ways for docker users to install MeCab from here.

1. Input 2 commands via Terminal, and change lwt if you named your container with other name.

docker exec -it lwt bash
apt-get update && apt-get install -y mecab libmecab-dev mecab-ipadic-utf8

2. Amended Dockerfile, copy and paste below command at Line No. 8 of Dockerfile.

RUN apt-get update && apt-get install -y mecab libmecab-dev mecab-ipadic-utf8

Thanks for your suggestion! I will add it to the documentation!

By the way, I noticed another error: the RegExp should alternate between mecab and \x{4E00}-\x{9FFF}\x{F900}-\x{FAFF}\x{3040}-\x{30FF}\x{31F0}-\x{31FF} but I think it wasn't, hence your problem. I pushed a fix right now.
