I am upgrading from vuetify version 1.0.5 to 2.3.10. I have removed node-sass and using sass as per the documentation. I am getting this error as below. I have included my package.json file. Any idea where I could be wrong?

Error update
yarn remove node-sass
yarn remove v1.21.1
[1/2] 🗑 Removing module node-sass...
error This module isn't specified in a package.json file.
It seems one of your other dependencies has a dependency on node-sass. It's probably #rails/webpacker as you are using very old version 3.2.0 (current is 5.2.1) and they switched to sass (dart-sass) recently
Result is you have both packages installed - sass and node-sass
From the docs of sass-loader (which is used by Webpack when building Vue app) it seems that when both packages are installed, they prefer sass over node-sass but at the same time warn not to install both. Seems strange to me. Also the error suggests that sass-loader is in your case preferring node-sass.
You have 2 options:
upgrade #rails/webpacker to newer version which is using sass
configure sass-loader to use sass as documented here
I'm realtively new to react-native. All my projects were running fine in the morning, but somehow they stopped working. When I run react-native start and the react-native run-android, the app gets installed on the device but then this error props up which was not happening before.
Loading dependency graph, done.

Ciao, this problem is connected to graceful-fs package. Plase, reinstall graceful-fs:
npm install graceful-fs --save-dev
And problem should be solved.
For me, npm cache clean —force was not working, and graceful-fs is not direct dependency in my project.
OS: Ubuntu
Node: 14.6.0
Npm: 6.14.7
I am still not sure why this error exits, but it works. I found this solution on Flavio Copes's post.
open file /node_modules/graceful-fs/polyfills.js, where the error comes from.
Here’s the function that gives the problem:
function statFix (orig) {
if (!orig) return orig
// Older versions of Node erroneously returned signed integers for
// uid + gid.
return function (target, cb) {
return orig.call(fs, target, function (er, stats) {
if (!stats) return cb.apply(this, arguments)
if (stats.uid < 0) stats.uid += 0x100000000
if (stats.gid < 0) stats.gid += 0x100000000
if (cb) cb.apply(this, arguments)
})
}
}
comment out these lines (line 62-64):
// fs.stat = statFix(fs.stat)
// fs.fstat = statFix(fs.fstat)
// fs.lstat = statFix(fs.lstat)
I've run into this problem while trying to start a react-native development server on one of my old projects - (React Native version 0.59.x). For me, the fix was downgrading the node version from 14 to 10 using nvm
Go to C:\Users(your username)\AppData\Roaming
Delete npm and npm-cache
Try running again if it gives the error again uninstall and delete Nodejs completely, check that those two files above are still nonexistent and then redownload Nodejs.
On one of my computers the first way worked no problems the second one needed to have Nodejs completely replaced and then worked.
here is the solution for it.
Option 1:
Follow this directory
C:\Users(your username)\AppData\Roaming
Delete the npm folder and if there is one mom cache folder.
Run npm clean cache —force ( — force is now required to clean cache)
You should be good now if not do option 2.
Option 2:
Follow this directory
C:\Users(your username)\AppData\Roaming
Delete the npm folder and if there is one mom cache folder.
Run npm clean cache —force ( — force is now required to clean cache)
Make sure everything to do with Nodejs is deleted and uninstalled.
Reinstall Nodejs.
You should be good now
I had to use node 12.3.1 and npm 6.9.0 to fix this error
nvm use 12.3.1
This installed both. npm install working again.
I've got a problem with my build process in relation to my React app.
I always get the following error:
Module not found: Error: Can't resolve 'core-js/es6'
if I use this in a polyfill.js:
import 'core-js/es6';

Can someone help here?
The imports have changed for core-js version 3.0.1 - for example
import 'core-js/es6/array';
and
import 'core-js/es7/array';
can now be provided simply by the following
import 'core-js/es/array';
if you would prefer not to bring in the whole of core-js
I found possible answer. You have core-js version 3.0, and this version doesn't have separate folders for ES6 and ES7; that's why the application cannot find correct paths.
To resolve this error, you can downgrade the core-js version to 2.5.7. This version produces correct catalogs structure, with separate ES6 and ES7 folders.
To downgrade the version, simply run:
npm i -S core-js#2.5.7
In my case, with Angular, this works ok.
Change all "es6" and "es7" to "es" in your polyfills.ts and polyfills.ts (Optional).
From: import 'core-js/es6/symbol';
To: import 'core-js/es/symbol';
After Migrated to New Angular Version or Version changed for core-js, core-js/es6 or core-js/es7 Will not work.
You have to simply replace import core-js/es/ in your polyfills.ts file.
For ex.
import 'core-js/es6/symbol'
to
import 'core-js/es/symbol'
This will work properly.
Change all es6 and es7 to es in your polyfills.ts
example:
import 'core-js/es6/reflect';
becomes
import 'core-js/es/reflect';
If you use #babel/preset-env and useBuiltIns, then you just have to add corejs: 3 beside the useBuiltIns option, to specify which version to use, default is corejs: 2.
presets: [
[
"#babel/preset-env", {
"useBuiltIns": "usage",
"corejs": 3
}
]
],
For further details see: https://github.com/zloirock/core-js/blob/master/docs/2019-03-19-core-js-3-babel-and-a-look-into-the-future.md#babelpreset-env
Sure, I had a similar issue and a simple
npm uninstall #babel/polyfill --save &&
npm install #babel/polyfill --save
did the trick for me.
However, usage of #babel/polyfill is deprecated (according to this comment) so only try this if you think you have older packages installed or if all else fails.
Ended up to have a file named polyfill.js in projectpath\src\polyfill.js
That file only contains this line: import 'core-js'; this polyfills not only es-6, but is the correct way to use core-js since version 3.0.0.
I added the polyfill.js to my webpack-file entry attribute like this:
entry: ['./src/main.scss', './src/polyfill.js', './src/main.jsx']
Works perfectly.
I also found some more information here : https://github.com/zloirock/core-js/issues/184
The library author (zloirock) claims:
ES6 changes behaviour almost all features added in ES5, so core-js/es6
entry point includes almost all of them. Also, as you wrote, it's
required for fixing broken browser implementations.
(Quotation https://github.com/zloirock/core-js/issues/184 from zloirock)
So I think import 'core-js'; is just fine.
Just change "target": "es2015" to "target": "es5" in your tsconfig.json.
Work for me with Angular 8.2.XX
Tested on IE11 and Edge
I got this error today (13 April 2022) after upgrade core-js version from 2 to 3 and after I tried to find the answer for several Hour, finally I can solved it after update my babel.config.js and make it like this:
Before:
presets: [ "#vue/app" ]
After:
presets: [ [ "#vue/app", { useBuiltIns: "entry" } ] ]
Notes
I'm using Vue in my project
I already try almost all question regarding npm uninstall core-js and tried to re-install it again npm install core-js --save or delete node_modules, package-lock.json, and yarn-lock.json but still failed to solved it
I can solved it if I downgrade core-js version using this line : npm install core-js#2.6.5, but it is not a good solution for long term condition
Explanation for this problem: this problem happens because the path for core-js/es6 in version 3 is already changed to core-js/es that's why your project can't find it the right path for the directory where it pointed to core-js/es6
It is vital that Webpack is able to resolve the import statements prepended to source files by Babel, for example
import "core-js/modules/es.object.freeze.js";
If such an import statement is inserted into a file which does not reside in a package which has core-js as a dependency, then Webpack may not be able to resolve its location on disk, resulting in a ModuleNotFoundError.
The solution for me was to specify the application's node_modules directory in the resolve section of my webpack.config.cjs:
module.exports = {
resolve: {
modules: [
path.join(__dirname, "node_modules"), // Contains core-js.
"node_modules" // Webpack's default.
]
}
}
And of course core-js is listed as a dependency in my application's package.json:
{
"dependencies": {
"core-js": "^3.19.3"
}
}
For Angular 14 I had to run npm i --save core-js
I kept the polyfills the same as in the Amplify docs:
import 'core-js/es/typed-array';
import 'core-js/es/object';
Im not sure why I'm getting this error:
Unable to resolve module `#expo/vector-icons` from `...(directory path here)...` : Module does not exist in the module pack
I have tried the following things suggested on other forums/sites:
Clear watchman watches
Deleting the node_modules folder
Reset packager cache
package.json
{
"name": "app name",
"version": "0.0.0",
"description": "Hello Expo!",
"author": null,
"private": true,
"main": "node_modules/expo/AppEntry.js",
"dependencies": {
"babel-plugin-module-resolver": "^2.5.0",
"babel-preset-expo": "^4.0.0",
"expo": "^21.0.0",
"firebase": "^4.5.1",
"geofire": "^4.1.2",
"moment": "^2.19.1",
"react": "16.0.0-alpha.12",
"react-native": "https://github.com/expo/react-native/archive/sdk-21.0.2.tar.gz",
"react-navigation": "^1.0.0-beta.13"
}
}
But still nothing, still getting this error
I resolved the issue by this command npm install #expo/vector-icons --save
I ran into the same issue. It's the babel-preset-expo. uninstall that and do the following
npm i metro-react-native-babel-preset --save-dev
delete the babel.config.json and create a new file called .babelrc
then specify the preset
{
"presets": ["module:metro-react-native-babel-preset"]
}
Sounds like vector-icons is another library you should be declaring in your package.json (https://www.npmjs.com/package/#expo/vector-icons)
Command npm install #expo/vector-icons --save do the trick !
The reason why I had this error, was because when I put useState in my app, VS Code auto imported it from react-native-vector-icons/node_modules/#types/react, instead of from "react"
I'm trying to learn react-native by creating an app using the expo development environment. I had a working app (little more than the code that shipped with expo) until installing redux. Currently I am getting the following error from the XDE:
Problem checking node_modules dependencies: Unexpected end of JSON input
and the following from the ios simulator:
undefined is not an object (evaluating 'ReactPropTypes.string')
Package.json:
{
"name": "myApp",
"version": "0.0.0",
"description": "Hello Expo!",
"author": null,
"main": "main.js",
"scripts": {
"test": "node node_modules/jest/bin/jest.js"
},

"react-redux": "^5.0.5",
"redux": "^3.6.0"
},
"devDependencies": {
"jest-expo": "~1.0.1"
}
}
I believe my node modules contain valid JSON. It should be noted that I'm using a more current version of react-native than expo. Is this an issue with the packages I have installed? Which files would be helpful in solving this?
Although I haven't been able to fix this particular error. This one and many others can be avoided by using yarn instead of npm when working with expo (I have no affiliation with either tool).
I believe this is due to a bug in the current release of npm 5. As mentioned in the other answer here, using npm 4 or yarn will resolve this problem.
