It is dangerous to run nodebb this way. Do so at your own risk.
I'm not sure exactly what is causing that npm error, but it's not a NodeBB bug. I suggest you look it up yourself.
After upgrade to 1.9.0, groups labels don't show up. Im using this theme https://github.com/pichalite/nodebb-theme-material.
https://github.com/NodeBB/NodeBB/issues/6433 theme needs this update
