OS 'DAR' not found for MeCab

[HugoFara]

when I open a text now, it shows the following...

Fatal Error: Your OS 'DAR' cannot use MeCab with this version of LWT!

@quopquai is using a Mac M2.

Hmmm, it seems I never tried MeCab with a Mac as I don't own one. I may ask you a small contribution @quopquai :smile:

First, did you install MeCab? It is not shipped with LWT and needs to be installed separately.

Second, can you open a terminal and tell me if this command works command -v mecab please? If so, I may add a support for MeCab Mac...

[quopquai]

...a contribution, sure, that sounds reasonable...!

I have no idea if I installed it or not!? I might have!?

...when I type the command, nothing seems to happen...

[HugoFara]

Okay, so MeCab is not installed. You need to install it first, and the previous command returns the location of the binary. Unfortunately I cannot recommend you a good tutorial as I don't have a Mac, but I already read that you can install it with homebrew.

Once that's done, we can work one an integration of MeCab for Mac!

[quopquai]

...ok I think I've done it...

[HugoFara]

Nice! Let's perform some live surgery on LWT!

Can you go to line 250 of kernel_utility.php (/Applications/MAMP/htdocs/lwt-2.8.1/inc/kernel_utility.php(268)), and do the following substitution?

From

if ($os == 'LIN') {

to

if ($os == 'LIN' || $os == 'DAR') {

If MeCab works with that, I'm adding the feature!

EDIT: just to explain a bit $os is you OS name ("LIN" for Linux, "DAR" for Darwin (Mac)...), so here we tell LWT to behave the same with Linux and Mac (|| means "or").

[quopquai]

...I changed it...and saved...

lwt is giving me this now:

Fatal Error: MeCab not detected! Please install it and add it to your PATH.

I think you installed MeCab on your computer, but MAMP cannot access its path and cannot find it. I'm not sure about how to solve it :thinking:

I'm looking online...

[HugoFara]

Please install it and add it to your PATH.

By the way, did you do that?

[quopquai]

...no, how do you do that?

[HugoFara]

I'm copy/pasting from https://apple.stackexchange.com/questions/41542/adding-a-new-executable-to-the-path-environment-variable

In your case, you can add usr/local/bin/mecab, then reload the server. I hope that will work :no_mouth:

[quopquai]

I'm sorry for the delay:

Macintosh:~ julisco$ usr/local/bin/mecab -bash: usr/local/bin/mecab: No such file or directory Macintosh:~ julisco$

I have no idea what is going on?!

[HugoFara]

I cannot be sure... I think the best solution for now is to try having a working instance of MeCab, then run LWT, and if it doesn't work you may need to configure MAMP to use the good path (I'm really not sure how MAMP works)...

[quopquai]

I found this in my terminal when installing MeCab:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

does it mean anything?

[HugoFara]

I have no idea what that is, sorry :disappointed:

MAMP (Mac users) Run the following in terminal to adjust the MAMP Apache server PATH:

printf 'export PATH="/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"' >> /Applications/MAMP/Library/bin/envvars

...finally jz from LUTE gave me the solution. ...now everything seems to work fine on Mac.

Thanks again HugoFara!!! :)

@HugoFara

printf 'export PATH="/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"' >> /Applications/MAMP/Library/bin/envvars

Add this in docs and close issue.
