npm install on Raspberry Pi not working

[amnotafraid]

When I try to install v4l2camera, I get an error. Is there any way to fix this?

I execute the following command:

npm install v4l2camera

I get this output:

> v4l2camera@1.0.4 install /srv/raspberry-pi-nodejs-barcode-reader-/node_modules/v4l2camera
> node-gyp rebuild

Try sudo npm install v4l2camera —I've noticed this is required for installing certain packages on Raspberry Pi.

In my case I did npm install --unsafe-perm
