After $npm install, Getting Error: Cannot find module '../lib/utils/unsupported.js'

问题

I just came back to work on a React project after working in the Rails environment and found that I cannot run any NPM commands in my Mac terminal. I've tried all the remedies that I have come across but none have worked. The bigger issue is what caused this and how can I avoid it again.

Here is the error. What do I need to do? Please help.

$npm install            

internal/modules/cjs/loader.js:550
    throw err;
    ^

I have tried the following:

$brew update
$brew uninstall node
$brew install node

After which the following commands come up as so when $which npm was unknown command before:

$which npm
/usr/local/bin/npm

$which node
/usr/local/bin/node

I even tried running:

/usr/local/bin/npm -v

but get the same error as above while

/usr/local/bin/node -v
v9.11.1

works fine.

added the following to my .zshrc file:

export PATH=/usr/local/bin/node:$PATH
export PATH=/usr/local/bin/npm:$PATH

I have also tried:

$brew uninstall --force node
$brew link --overwrite node 
Warning: Already linked: /usr/local/Cellar/node/9.11.1
To relink: brew unlink node && brew link node

$rm -rf /usr/local/lib/node_modules/npm

then,

$node install

but that does not work, either.

$echo $NODE_PATH

does come up empty, so I may need to added the following to my .bashrc.

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

That does not work either.

回答1:

Uninstall node brew uninstall --force node
Remove the /usr/local/lib/node_modules folder
Install it again brew install node

回答2:

Assume this happens on MacOS, below solution works for me.

brew uninstall --force node
Visit https://nodejs.org/en/ and download the LTS version and install, the error was gone

回答3:

This happened to me after installing yarn.

in a terminal:

brew uninstall --force --ignore-dependencies node
brew install node

if you have trouble symlinking node, in the same terminal:

sudo chown -R `whoami`:admin /usr/local/include
sudo chown -R `whoami`:admin /usr/local/bin
sudo chown -R `whoami`:admin /usr/local/share
sudo chown -R `whoami`:admin /usr/local/lib
brew link --overwrite node

Check that your re-installation worked by typing the following in the terminal:

node -v

I had an issue after upgrade my mac. I tried different solutions available on stack overflow and nothing work for me.

This solution works for me.

Uninstall node all version brew uninstall --force node
Install it again by this brew install node

First point remove all node versions if available.

Done. Enjoy coding.

Try this one: https://gist.github.com/DanHerbert/9520689

"If you're a Homebrew user and you installed node via Homebrew, there is a major philosophical issue with the way Homebrew and NPM work together."

Kudos to Dan Herbert for the solution.

回答6:

Remove all file from following folder

A)C:\Users\\AppData\Roaming\npm

B)C:\Users\\AppData\Roaming\npm-cache

and install node again

then execute command "npm install -g @angular/cli"

回答7:

None of the other answered solved my issue. After reinstalling Node, I still got the same error (even when I just wrote npm -v).

I followed this answer here (removing everything called node and npm), which solved it for me.

回答8:

In my case, the solution to the problem was reinstalling the node using the official installer from https://nodejs.org (Mac OS).

Solution:

Download node installer from https://nodejs.org
Install it

P.S. The problem appeared after yarn installation.

回答9:

I'm sorry, but in my case I get the same error, because, my index.js is inside de src folder, make sure that you are in the seme directory of your index.js to run

回答10:

In my case, this happened after I performed a machine-wide clean-up of all node_modules folders. I had node installed with nvm and I started getting this error, no matter what node-related action I wanted to trigger:

Error: Cannot find module '../lib/utils/unsupported.js'

I solved it by doing the following:

Restarted my computer
Uninstalled nvm
Installed a different node version

回答11:

One other suggestion after trying these that finally worked for me was simply upgrading my node by downloading the latest via the download and package installer from here:

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

Before doing this trying to run any npm command gave me the same error brought in OP's question

npm commands started working for me after that.
