Answer 1

You could also reinstall node from https://nodejs.org/en/download/current/

Answer 2

I followed the instructions above (what eush77 said) to remove the npm folder in the node_modules folder. But there remains the broken link resulting in this error message.

/usr/local/bin/npm: No such file or directory

so remove the broken link:

rm /usr/local/bin/npm

and then make it point to the right place like this:

sudo ln -s /usr/lib/node_modules/npm/bin/npm-cli.js /usr/local/bin/npm

Answer 3

I got it reset by using the official installer package found: https://nodejs.org/en/

Playing around with n and nvm eventually corrupted the node_modules packages for me by providing packages incompatible with current Node version.

I suspect it'd work for other environments as it couples both Node AND npm install.

Answer 4

I just had the same problem while deploying the project on local server when I was invoking the yarn dev command.

After going through all the blogs, articles and stuff I got it working just by simple this 2 commands.

1. npm list check at what version it is pointing right now. For me, when I was getting this error. It was pointing to the system.

2. I just used the nvm use v{VERSION} e.g. nvm use v10.5.0 (for me) and it got working. All the errors went away and the project got deployed successfully while invoking the yarn dev. Try this before doing anything else. I highly recommend.

Answer 5

What eush77 said, but if you're on Windows:

download the latest package from https://nodejs.org/download/release/npm/

unpack, and replace the "npm" directory in the nodejs node-modules directory (by default C:\Program Files\nodejs\node_modules)

Answer 6

For me this had to do with installations being corrupted and perhaps ubuntu repositories not being compatible or the most recent. The following resulted in a working npm/node install:

sudo curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash - sudo apt-get install -y nodejs
