Installing plugins in NodeBB

[ok-n]

Hi everyone!
(Request to administrators to move to the appropriate category)
I installed the NodeBB forum and I use cloudron.
I wrote a new plugin for NodeBB, and when I try to install it directly from the terminal I get an error that the files are read-only.
Even when I opened a project on GitHub and uploaded the plugin files there, and tried typing the command:
/usr/local/bin/gosu cloudron:cloudron yarn add nodebb-theme-XXXX
I still got the same error.
Can someone help me figure out where my mistake is?
Thank you!

Can you paste the error you are getting? Or a screenshot?

Here is the project in Git
Here is the project in Git - this is a beta version for initial testing. The plugin is intended for custom registration for the nodbb forum
The errors I get:
Error: EROFS: read-only file system, open '/home/cloudron/.yarnrc'
I typed the following commands in the console but I still got the same error:
cd /app/code
/usr/local/bin/gosu cloudron:cloudron yarn add https://github.com/oknet8020/nodebb-plugin-custom-registration.git
Thank you very much!

@ok-n for me, it fails like this

error Custom Registration Fields@1.0.0: Name contains illegal characters

(the yarrnc error is corrected in the latest base image , but you can ignore it)

I think there is no id field in package.json , just a name field https://github.com/oknet8020/nodebb-plugin-custom-registration/blob/main/package.json#L3C1-L3C40 . name field has no space and no capitals afaik
