SyntaxError: Unexpected end of JSON input in npm run command - npm

I'm working on Laravel project where using node version: v8.12.0 and npm version: 6.4.1. When I ran npm run watch command, I get error referenced to attached picture.

Ohh after a hard job finally got the solution: Just deleted : public/mix-manifest.json And then run : npm run watch It is working fine for me.

Error "Cannot read property "matches" of undefined" when using "npm install"

I'm trying to install expo globally on my Windows 10 machine for a school assignement.
As the doc says, I've been trying the following command in my terminal :
$ npm install --global expo-cli
but it always gives me the same error :
npm ERR! Cannot read property 'matches' of undefined
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\User\AppData\Local\npm-cache\_logs\2021-04-07T13_43_16_562Z-debug.log
I've tried running $ npm install -g expo-cli instead but the same thing happens.
I haven't tried reinstalling node or anything yet because I need my pc up and running for this week and I'm not too accustomed to all that, I'd like to keep that a last resort if possible.
Has anyone ever encountered this error before ?
Thanks to those who replied but I "accidentally" fixed it myself.
Through my searching I ended up actually uninstalling node with $ nvm uninstall v15.0.0 and I found myself obligated to download it again here.
Must've been a problem with the version I was using as suggested before.
Try removing the node_modules folder and package-lock.json file and run command npm install.

NPM Error: EPERM: operation not permitted. Tarball data for <package> seems to be corrupted

I've been trying to create a new angular app with the cli, but I keep getting this error.
At first I thought it was something related to the version of cli I had installed( the latest one), so I uninstalled it and tried with the same version(6.0.8) that is used in the course I'm following along, but I get the same error :
Do you have any idea how I can figure out what is causing this issue?
Is there any log I can check?
I'm using :
Node: v8.11.3
Npm: 6.4.1
Windows 10 Pro.
I resolved it using this command:
npm install --registry https://registry.cnpmjs.org

npm ERR! Unexpected end of JSON input while parsing near '...":{"shasum":"ae6c2edf'

npm ERR! Unexpected end of JSON input while parsing near '...":{"shasum":"ae6c2edf'
getting this error while npm install.
Steps i had done
1. create a new project
2. done npm install
getting this error for all new projects.
Cleaning the corrupted local npm cache may fix this error.
npm cache clean --force
Just run your npm command again after executing the above command in your terminal.
There could be few other reasons for the invalid JSON, as described in the official documentation here.
The official npm website has well documented most of the common errors. But unfortunately they don’t appear on the top results when you google the error.
updating angular cli to latest worked for me.

skeleton-typescript-webpack fails when running npm start or npm run build on Windows 7

I'm running Windows 7 64bit with Node v6.5.0 and NPM 3.10.3. I ran npm install in the skeleton-typescript-webpack folder and all the packages installed fine. When I run any commands that call webpack though, I get the errors below.
When I run npm run build I get this error:
When I run npm start I get this error:
As you can see, the command that is run before the npm build error happens is concerning webpack, and same with the command that is run before the npm start error happens.
Anyone have an idea on how to fix this?
The skeleton skeleton-typescript-webpack uses TypeScript 2.0 for compilation.
This gives tries to compile adm-zip which is in the selenium-webdriver node module. And this gives an error on a break statement after a return statement.
The file .\nodes_modules\selenium-webdriver\node_modules\adm-zip\zipEntry.js gives the issue. You have to comment out two break; statements in the file on line 96 and line 115. After this you get a correct build.
