Error: Cannot find module 'commander' at Function.Module._resolveFilename

When I'm running sails -v, sails lift or even installing npm, I am getting this error. How can I fix it?

Solution

  • Uninstalling sails and reinstalling with 'sudo' resolved it.

    npm uninstall sails -g

sudo npm install sails -g
