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

Question

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;
    ^

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

    at tryModuleLoad (internal/modules/cjs/loader.js:506:12)

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.

do you have `require('../lib/utils/unsupported.js')` somewhere in your code? — Bryan Chen, Apr 06 '18 at 05:13
No, I don't have any reference to unsupported.js. NPM commands don't work on any project or directory. — bigmugcup, Apr 06 '18 at 05:22
Looks like I was able to fix the issue by downloading and installing Node from https://nodejs.org. Did $brew uninstall --ignore-dependencies node, then downloaded and installed from nodejs.org. I have no idea why the brew installation of Node and NPM stopped working. If anyone has any idea, please let me know. — bigmugcup, Apr 06 '18 at 05:41

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

Same here, only worked after removing the`/usr/local/lib/node_modules` folder. @Lucas Lopes, maybe update your answer to add that? – Ioanna Nov 19 '19 at 05:58

i had to remove `/usr/local/lib/node_modules/npm` only and not the whole folder `/usr/local/lib/node_modules` – Zorox Feb 21 '20 at 23:25

First should install the brew command : sudo apt install linuxbrew-wrapper After run the 1. uninstall node command then remove the folder using this command : sudo rm -r /usr/local/lib/node_modules. finally run the 3 and press Enter – Dilshan Dilip Feb 23 '20 at 17:55

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

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

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.

His suggestion of --without-npm did not work for me. That is an invalid option – tettoffensive Feb 27 '19 at 17:06

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.

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.

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.

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

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
