Cannot download node-sass HTTP error 404 Not found --- Node Gyp error

Question

I am working on a project for an internship on Angular and after trying to install a few modules from NgPrime I m getting the following errors every time I run an npm install regarding:

1. node-sass(cannot download)
2. node-gyp

Here is what I get after running npm install:

> [email protected] install C:\Users\flaviu.cristian\Desktop\BSS\TrackGPS.BSS.Web\node_modules\@angular-devkit\build-angular\node_modules\node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.10.0/win32-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.10.0/win32-x64-72_binding.node":

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

Initially after downloading the project and running for the first time npm install everything worked fine.I have tried to get back to my previous commit on git where everything was working but it did not solve my problem.

If there is any file that would might help you get a better understanding of the errors I will gladly post it

Answer 1

v4.10.0/win32-x64-72_binding.node - simply does not exist.

As far as I can tell - you can only use a certain node-sass version range with a specific Node.Js version.

https://github.com/sass/node-sass#supported-nodejs-versions-vary-by-release-please-consult-the-releases-page-below-is-a-quick-guide-for-minimum-support

So in your case: When you are using Node 12 - you must update to [email protected]

This should get rid of the errors.

This is explained in the repos FAQ:

https://github.com/sass/node-sass/blob/master/TROUBLESHOOTING.md#404s

Answer 2

NPM version is outdated.

That is the reason that not find the dependency.

After searching all over the places finally I found the solution

npm install -g npm@latest
