npm "Invalid response body while trying to fetch". npm can't install any dependencies

Question

Good day everyone! I recently worked through this error message:

npm WARN config global --global, --local are deprecated. Use --location=global instead

by editing the 4 necessary files (npm, npm.cmd, npx, npx.cmd). Problem is, now I can't install any dependency and I can't use npx (for example for npx create-react-app my-app).

When trying to install a dependency

Running npx

What I have tried so far:

• npm cache clean –force
• npm chache verify
• Deleted the npm-cache folder under 'C:\Users\reaga\AppData\Local\
• Completely uninstalled Nodejs and reinstalled the LTS
• Completely uninstalled Nodejs and reinstalled the current version
• Changed the npm-cache folder's location using npm config set cache C:\reaga\nodejs\npm-cache --global
• Deactivated antivirus

On the flip side yarn seems to be working so I have no problems running yarn add express for example. Any help would be very much appreciated!

Answer 1

The solution I followed to solve this problem:

1 - Go to folder C:\Program Files\nodejs

2 - You have to edit 4 files named : npm, npm.cmd, npx, npx.cmd

3 - Open the files in a text editor, like [ Visual Studio Code ]

4 - Replace prefix -g with prefix with location=global in all 4 files, make sure didn't use -- and Save all (if asked, save as administrator)

Like a picture.

Good to go!
