use this method to remove npm and node: https://stackoverflow.com/questions/20711240/how-to-completely-remove-node-js-from-windows

then install nodejs LTS from nodejs.org

prasannaballal commented 5 years ago

@subhrajitroy1989 npm i core-util-is

doing this only worked for me.

gireeshpunathil commented 5 years ago

@subhrajitroy1989 - is this resolved?

radurentea commented 5 years ago

What worked for me is to make sure the webpack-dev-server is up to date, so run the following command: npm install webpack-dev-server

gireeshpunathil commented 5 years ago

resolved, closing

Struggled with this error all day using a MERN stack. I fixed it by adding this line to my package.json in on the server side.

I want to run my Vue.js using npm on localhost:8080 but they give me this error. Is there a way to solve this issue?

This error only occurs when I tried to install node_modules and package-lock.json in my Vue folder containing .babelrc, package.json and webpack.config.js. For my other Vue folders, I still can run my localhost:8080 by using the same method for all folders which is

npm install
npm run dev

The code below is the Error.

My error was:

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module 'theFilePath'

I think I had some other error number at some point also.

Using: Win 10 nodejs v10.16.3 typescript, express, mongoose, (more modules that are not relevant)

Scenario: I was trying to use a file outside src folder. When compiling and trying to run I got that error.

My solution was: I moved the file from outside src in to the src folder and the error was gone.

Hope this helps someone doing the same thing as me. 🙂

How you solved it?? I have the same problem

QuentinIcky commented 4 years ago

Verify your hierarchy. I already had this issue, my server.js was in the wrong directory. Everything worked after

server.js?? What's this file? But the scaffold is builded by nestjs-cli generator.

QuentinIcky commented 4 years ago

@Zacknero in your case I think ScrapeExample.js is the file corresponding to my server.js

Zacknero commented 4 years ago

@QuentinIcky i never created the ScrapeExample.js...this create the cli of nestjs....Because i don't find this on my pc :S :S

chavychaze commented 4 years ago

Mostly this error's occured when the nestjs wasn't installed correct globally, the best option to fix this, is try to reinstall it, in case, that after creating the file manually to fix one issue, you'll got to do it each time, when generating new modules with nest. Hope this help someone

DhritishRoy commented 4 years ago

I am also having the same problem just like @Zacknero , the same error and I tried by reinstalling npm globally also I checked my directory also and the npm installed is also of latest version. Can someone kindly sort out this problem, will be a real help.

I solved my issue by removing single quotes ' from my package.json config.

ex, from

"scripts": {
 "dev": "webpack-dev-server --config './webpack.config.js'",

to

"scripts": {
 "dev": "webpack-dev-server --config ./webpack.config.js",

If this doesn't work, make sure your "main": {..} actually points to the main file, and delete node_modules/, package-lock.json and install everything npm i

Zacknero commented 4 years ago

ackage.jso

My package.json have this scripts:

"scripts": { "prebuild": "rimraf dist", "build": "nest build", "format": "prettier --write \"src/**/*.ts\" \"test/**/*.ts\"", "start": "nest start", "start:dev": "nest start --watch", "start:debug": "nest start --debug --watch", "start:prod": "node dist/main", "lint": "tslint -p tsconfig.json -c tslint.json", "test": "jest", "test:watch": "jest --watch", "test:cov": "jest --coverage", "test:debug": "node --inspect-brk -r tsconfig-paths/register -r ts-node/register node_modules/.bin/jest --runInBand", "test:e2e": "jest --config ./test/jest-e2e.json" }

I don't have your dev script, or must add it? Thanks!

samayo commented 4 years ago

Nah, dev is just an identifier to start the webpack dev server, in your case it is start:dev your should probably delete node_modules, package-lock.json and run npm i

Had the same problem under macOS Catalina. A reinstall of the latest Node LTS version from (https://nodejs.org/de/download/) solved my problem.

What worked for me is to make sure the webpack-dev-server is up to date, so run the following command: npm install webpack-dev-server

This worked out well !

Hi Guys,

If you have a project dependency on a particular version of npm, please don't update it. It's hectic to update the dependencies and resolve them one by one. So, it would be wise to uninstall the existing core-util.js which got corrupt. Please install the compatible core-util.js for the npm version and the issue will get resolved.

Thanks & Regards

Subhrajit Roy
