Lua error: error loading module 'socket.core'

[thosoo]

Hi,

I am trying to run this on an old android phone inside a termux environment to use it as a wireless music station. Unfortunately I am gettings the following error:

~/KH-Disc 1 $ mpv .

lua -v gives me

Additionally, luasocket I have installed using luarocks the following way:

Any advice how I could get this script running properly? Thanks

I'm getting the same error. Did you manage to solve it?

No, unfortunately not.

I do not use mpv on android personally. I've tried to get it to work within termux, but ran into the same problems, as described in this issue.

This is an issue with termux + mpv + lua + lua packages in general and not directly related to simple-mpv-webui. So you might have more success getting support from the guys at mpv or termux.

As there is nothing I can do here, I'm gonna close this issue. If you feel that this is in fact related to simple-mpv-webui (i.e. other lua scripts are working with additional lua dependencies), feel free to reopen.

Edit: The problem is not with termux + mpv + lua in gerneral, but only with additional lua packages.

@thosoo great! Please see my updated comment above. The problem doesn't stem from mpv + lua alone, but only if the script depends on additional lua packages.
