Npm install cannot find module 'semver'

Question

I had the same error. npm uninstall npm -g, rm -rf node_modules didn't help me, because when I tried I was getting Error: Cannot find module 'semver'. But I solve my problem with these steps (this will delete other global modules you may be using):

• sudo rm -rf /usr/local/lib/node_modules
• sudo rm -rf ~/.npm
• brew uninstall --force node
• brew install node

Hope this will help those who are getting a similar problem.

I'm facing the same issue here.

If this occurs right after you run brew install yarn try running yarn global add npm and voilà - fixed!

On MS Windows, the solution is to remove %APPDATA%\npm and reinstall node

I had this too, after running brew install yarn yesterday. At least, everything was fine up until then.

I ran rm -rf node_modules and tried to reinstall, but no npm command was working.

In the end I took the rather simple step of reinstalling Node via the official Node installer for Mac OS X.

https://nodejs.org/en/download/

Everything is fine now. Just went back to the directory, ran npm install and it's done the trick.

if you are in Linux server exit from the server and re ssh

On Arch Linux what did the trick for me was:

sudo pacman -Rs npm
sudo pacman -S npm

On Ubuntu, if you would rather manage Node through the default repositories using apt, it's best to install both nodejs and npm this way.

It's very likely that the version of npm you are using is expecting semver in a specific place that is not aligned with the version of Node JS you have installed. If there is only one version of nodejs and only one version of npm, and they are both installed using the default repositories, this should work perfectly.

Here is my best guidance for getting Node and npm working using the main Ubuntu repositories:

0. sudo apt-get purge nodejs --auto-remove and sudo apt-get purge npm --auto-remove
1. whereis node: remove all the versions of node, one at a time. Repeat until this command returns a blank after node:.
2. sudo apt-get install nodejs
3. node --version: should return ... no such file or directory
4. nodejs --version: should return v1x.x.x. This is the version installed by apt. It will probably be less recent that the latest version available on the Node JS website.
5. sudo apt-get install npm
6. npm --version: it will use the nodejs installed by apt and work correctly.
