I want to develop a Joplin plugin and was following these intructions to set up a dev environment on Ubuntu:
https://joplinapp.org/api/get_started/plugins/
But unforunately I got stuck with yo joplin which fails on npm install executing webpack --joplin-plugin-config buildMain && webpack --joplin-plugin-config buildExtraScripts && webpack --joplin-plugin-config createArchive
I tried to debug this. But all I currently know is, that the webpack --joplin-plugin-config buildMain seems to fail creating the necessary directories.
Maybe CopyPlugin fails - but this is just a guess.
From my point of view the Linux directory permissions are fine. Ownership of all files/dirs are good and I didn't found any suspicious permissions in ne working directory.
Any ideas?

If I try to install fsevents I'm receiving this error:
npm ERR! code EBADPLATFORM
npm ERR! notsup Unsupported platform for fsevents@2.3.2: wanted {"os":"darwin"} (current: {"os":"linux","arch":"x64"})
npm ERR! notsup Valid OS: darwin
npm ERR! notsup Valid Arch: undefined
npm ERR! notsup Actual OS: linux
npm ERR! notsup Actual Arch: x64
It turns out, that running the install script from a Linux partition that is mounted with the ´noexec´ mount-option was causing this error
