Npm Please try using this command again as root/ad

Question

I've been desperately trying to install modules using node.js but it always fails getting packages with npm.

I logged in as Administrator and used powershell/cmd with "run as administrator". I also had problems with the registry so I used npm set registry http://registry.npmjs.org/

I tried everything... it just drives me nuts.

Here are the errors:

npm ERR! Please try running this command again as root/Administrator.

Answer 1

I had to login into npm to resolve this issue.

npm login

Answer 2

I solve it running as administrator cmd. Cleaning the cache npm cache clean -f And then try to install the package again

Answer 3

If you are doing this on mac type: sudo chown -R $USER /usr/local that will give you administrative access to your files

Answer 4

As a hack,

Check if the folder path it is complaining exists or not. If not, try creating them manually and rerun the installation, after clearing the cache

I had success with this, when running the installation from command prompt as an Administrator didn't work

Answer 5

I had the same problem, what I did to solve it was ran the cmd.exe as administrator even though my account was already set as an administrator.

Answer 6

This worked for me, if your package.json is not too big you can do this:

• Signout then signin.
• Delete node_modules.
• npm install again.
