“sudo npm install -g grunt-cli” gives me an error

Question

I get an error when trying to install gruntjs on a linux 12.04 (with a mirrored packages source)

Here is the error:

 sudo npm install -g grunt-cli

Answer 1

This blog worked for me :

http://slopjong.de/2012/10/31/how-to-install-the-latest-nodejs-in-ubuntu/

the error was because in ubuntu v12 few of the dependencies were not available for the latest version of Node.

I've had this problem before; sometimes for global packages your current working directory has to be ~/ (but I'm not sure why this is!). Try:

cd ~/; sudo npm install -g grunt-cli

Answer 3

According to the maintainer of npm, installing packages with sudo is considered bad practice because you are allowing that package to have complete control of your system and you can't and SHOULDN'T trust these packages with root access. Think Debian's long release cycles as an extreme example of protecting end users from community maintained packages for this exact reason.

You should do what Issaacs suggests and chown your /usr/local folder so you have RW permissions.
