Plugin activation failing - npm ERR! cause: [Error: EACCES: permission denied, mkdir '/var/www']

Here is the error I get:

PerformanceAudit plugin activation failed due to the following error:
NPM has the following unexpected output:

However, my matomo is in /srv/matomo. Not sure what NPM is trying to do here.

Let me know if I can provide more info!

@angristan here are the files/dir NPM is trying to create :

root@b2d:/var/www# tree .npm/ -L 1
.npm/
├── anonymous-cli-metrics.json
├── _cacache
└── _locks

I had to create .npm dir to let the plugin work.

If I may, you'll need chrome/chromium headless as a dep as well.

Turns out I didn't have any /var/www folder 🤔 Simply creating it and giving www-data permissions on it fixed it.

And yes, afterwards I needed some dependencies but the error is self-explanatory. 😄

Thanks @dadall o/
