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

There is an option to bump npm without reinstalling node.

#### # this will remove current npm
rm -rf /usr/local/lib/node_modules/npm/

#### # install npm from sources. Version 3.5.x will be installed
apt-get update
apt-get install npm

#### # install the newest npm version. Bumping from 3.5.X to 6.14.X goes without any issue :)
/usr/bin/npm install npm@latest -g

#### # additionally, npm with version 3.5.x is not added to $PATH, so it's not used.

Thanks for the answers. It was a bug and it has already been fixed in Node v5.4.1. Now it's working as usual.

Answer 3

Some of the answers already answered the question, but I will still like to throw in my own idea. I encountered same issue after I was told to run npm update -g npm after running that piece of code, the error started. I solved mine by using Node Version Manager(nvm):

nvm install 8

Note: not actually 8, but to a version of your choice e.g(6,5). Writing the version number will automatically install the stable of the version specified. After the installation you should get a CLI message:

Now using node v8.11.4 (npm v5.6.0) 

Answer 4

It looks like npm update -g cannot update npm to the newest version. I solve the problem by updating npm installation manually.

1. Install/ reinstall node to get the bundled npm
2. run npm install -g npm@3.5.4 to update the global npm installation
3. now npm update -g should work

Answer 5

I have faced the same issue in my Windows 10 PC. After looking into solutions, since i couldn't find the exact solution for the issue i was facing Cannot find module 'npmlog' I just uninstalled the node js and then, deleted both 'npm' and 'npm-cache' in "C:\Users\YourPCName\AppData\Roaming"

Then, i downloaded the latest version of node from Node JS Website

And, installed node js

After that i checked with the path in environment variables.

Finally run the command prompt 'run as administrator' and npm install npm -g

Checking your version will show the latest version. 'npm -v'

I got the latest version - v3.10.9

Try this. this should work.

Answer 6

What fixed this for me was

sudo rm -rf /usr/local/lib/node_modules/

and then re-installing node (with npm).
