Node.js Question

npm install fails on FAT32 sile system

I'm trying to run

npm install
in a folder on my FAT32 drive, and this is the error I'm getting:

$ npm install
└── (empty)

So far I understand that the problem is caused by FAT32 not supporting symlinks and/or chmod. But is it really true that there's no work-around for this?

There is an issue open for this on GitHub, where maintainers agree that this is a bug and should be fixed, but the thread has been idle for over a year now.

Also in the same thread user mgiorgino mentions that
npm install
run under Windows does not make this error. I don't have a chance to confirm this, so is there anyone on Windows who was able to successfully run
npm install
on a FAT32 file system? If yes, is there any way that we get the same functionality under Linux?

Finally, looking around the web I found FAT32 file system driver and FAT16/FAT32 filesystem implementation packages. Since both their documentation is very scarce, so I can't tell if they can help fix this problem?

Try updating npm by running npm install npm@latest -g. I ran that command and it updated to v4.0.2. The recent updates could contain a fix if it is code related. Command in footer of the npm docs page.

Disabling symlinks helped a number of users when using npm install on systems unable to create symlinks. To turn off npm using symlinks set bin-links to false in the npm config by running npm config set bin-links false. Optionally you can run npm install --no-bin-links each time. The first command makes the change to the npm config so you don't have to add the --no-bin-links flag each time you run npm install. This is the method recommended in the npm config docs to get npm working on systems/drives that don't support symlinks.
