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/](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?

output of `npm install`

```auto

and that's what the logfile says

It turns out, that running the install script from a Linux partition that is mounted with the ´noexec´ mount-option was causing this error 🙀 🙈
