Error when installing http-server npm package. Permission denied.

Here's the error I get when I try and install http-server globally. I was using the link provided in the teacher notes for instructions on http-server. Any help? I am a beginner with the terminal and I am uncomfortable taking chances here.

Hi Mindy,

You simply need to run the npm command as sudo as the default location for NodeJS packages on OS X is protected by the admin group.

sudo npm install http-server -g

You will just need to enter your account password but after that, the installation of http-server will succeed.

Happy coding!

Thanks a bunch. That worked perfect.

Thanks! I didn't realize the permission required was mine. haha.

Go to your lib folder and assign full permissions, you can do it through the terminal by writing chmod 777, remember to go to the folder before you run that command

As mentioned in my reply below, this error is caused by group level folder permissions that restrict users from writing to it. It is highly recommended not changing permissions to system folders as it can create system level vulnerabilities.
