🚀 Fixing the NPM Install Error: Unexpected end of JSON input 🚀

So you're trying to create a new Angular 5 project, but you're facing a pesky error that says "Unexpected end of JSON input while parsing near '...nt-webpack-plugin":"0'". Don't worry, you're not alone! This error often occurs when there is a problem with the JSON file NPM is trying to read during the installation process. Lucky for you, I've got some easy solutions to get you back on track!

Possible Causes 🤔

Behind this error could be a few different issues, such as:

1. A corrupted or incomplete package.json file.

2. A network interruption or slow internet connection during installation.

3. An outdated or incompatible version of NPM or Node.js.

Easy Fixes 💡

Now that we know what might be causing the error, let's dive into some solutions!

1. Remove package-lock.json and node_modules

Sometimes, the error can be resolved by simply deleting the package-lock.json file and the node_modules folder within your project directory. These files will be regenerated when you run the npm install command again.

To do this, open your terminal and navigate to your project directory using the cd command. Then run the following commands:

rm -rf package-lock.json
rm -rf node_modules

After deleting these files, try running npm install again and see if it works!

2. Clear NPM cache

The next solution is to clear your NPM cache. This can help resolve issues related to outdated or corrupted cached data. To clear the cache, run the following command:

npm cache clean --force

Once the cache is cleared, try running npm install again and see if the error persists.

3. Update NPM and Node.js

Sometimes, an outdated or incompatible version of NPM or Node.js can cause this error. To update NPM, run the following command:

npm install -g npm@latest

To update Node.js, visit the official Node.js website (https://nodejs.org) and download the latest stable version. Follow the installation instructions specific to your operating system.

After updating NPM and/or Node.js, try running npm install again and see if the error disappears.
