I am running node and npm on a raspberry pi 4 with the newest release of raspberry pi OS. Please explain what is going wrong and how to fix it

CodePudding user response：

Looks like you're trying to install on your SD card or USB drive, which I assume is formatted as FAT32. Unfortunately, FAT32 doesn't support symlinks.

You could try this:

npm install --no-bin-links express

If that doesn't work, you'll have to use a filesystem other than FAT32.

Seems to be a permission issue.

if you're on mac, run:

sudo npm install express

if you're on windows I am not sure of the equivalent, but you have to run as administrator.
