Error “Cannot find module 'npmlog'” after “npm update -g”

Question

I have NVM 0.30.1 and used it to install node.js v5.4.0 (with NPM 3.5.4) on Fedora 22. When I run npm update -g, I receive the following warnings:

Answer 1

If people with linux are facing the problem, here is the solution:

As of the date of this post, the NPM version packaged with Nodejs doesn't work. If you installed this package, run

sudo rm -rf /usr/local/bin/npm
sudo apt-get install node
sudo mv /usr/bin/npm /usr/local/bin/npm

New version should be 3.10.8 and the old error gone

Answer 2

If you're using a Mac, perform the following steps, to remedy (assuming you have Homebrew installed already):

sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*

(to overcome bash: /usr/local/bin/npm: No such file or directory error):

hash -r 

Then go ahead with updating brew (to keep its kegs up to date) and the reinstallation process, linking is optional.

brew update

brew reinstall node

brew link --overwrite node

At any point inbetween you can use npm -v or node -v to test whether or not you are making progress. If you have node returning a version, but not npm then you will need to add your path to your environment with:

export PATH="/usr/local/bin:$PATH"

Answer 3

init-package-json, node-gyp, npm-install-checks, npmlog, read-package-json didn't installed correctly. Not sure why though.

Didn't find the root cause for the issue but I used the hacky way to install the packages above for now:

• Roll back to the previous node version which npm didn't be updated. For example, nvm use iojs
• cd to where npm installed, for example, cd /home/peflorencio/.nvm/versions/node/v5.4.0/lib/node_modules/npm and reinstall those packages like rm -rf node_modules/init-package-json && npm install init-package-json etc.
