npm install -g mongodb

it outputs as follow:

npm http GET https://registry.npmjs.org/mongodb
npm http 200 https://registry.npmjs.org/mongodb
npm http GET https://registry.npmjs.org/mongodb/-/mongodb-1.0.0.tgz
npm http 200 https://registry.npmjs.org/mongodb/-/mongodb-1.0.0.tgz

npm not ok

My system is ubuntu 12.04 LTS x86_64 and I running the npm as root user.
Not sure wether it matters, I install node from source to /opt/node/0.6.17/ and added the path in $PATH
I tried re installing node v0.6.17 but the same result.

So, why doesn't root have write access to ~root?

Solve that problem, and it will work.

I purplexed too. I can freely access my /root without any problem.

Try this:

$ node
> require('fs').mkdirSync('/root/.npm', 0755)

What does whoami return?

Is it possible that /root is a read-only file system mount or something? (Though, then it shoudl be returning EPERM, not EACCES.)

I had the same problem (using Fedora 16), and solved it by running chmod -R g+w . while in my /root directory. The -R may have been overkill though... but whatever.

Anyway, maybe npm was running as the root group rather than the root user?

Oh, probably because you were running as root, it's setuid'ing to the "nobody" user. You can run with --unsafe-perm (or npm config set unsafe-perm true to make it stick) to go ahead and let it remain as root.
