Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/node-sass/build'

Question

I am trying to run an Angular application. I execute the ng serve command, but it then shows:

Error: Cannot find module 'node-sass'

Answer 1

Solution:

You need to change the ownership of folder node_modules, because you use sudo npm install -g node-sass, so its ownership is set to root.

To change the ownership to the current user as group -

sudo chown -R root:$(whoami) /usr/local/lib/node_modules/

sudo chmod -R 775 /usr/local/lib/node_modules/

And never use sudo for an npm-related query.

Answer 2

Run this command

sudo npm install -g <ModuleName> --unsafe-perm=true --allow-root

Answer 3

Try this

sudo npm install -g --unsafe-perm node-sass

Or this

sudo npm install -g --unsafe-perm --verbose @angular/cli
