node-sass and python ERROR during npm install

Question

I cannot run a project, here is the console log, could you please help me? It seems there is an issue with node-sass and Python... How can the node-sass URL be 404... I do not know where I should configure this

$ npm install

What I did, I'm not sure what solved the issue, but now it is working:

• Install Python Download and install python for windows (accept the option to add to PATH) from: https://www.python.org/downloads/windows/ Add python folder to your PATH, the one to python/python39. I also added an other variable names python2 in my own windows env variables

• re Install Nodejs then execut the following commandes:

  • npm link @angular/cli
  • npm rebuild node-sass
  • npm --add-python-to-path='true' --debug install --global windows-build-tools
  • npm install --global node-gyp

Finaly I add a new package.json file into my lib projet:

{
   "name": "menuT",
    "version": "1.0.0"
}

And at the end, I was able to execute the last commande:

ng build menuT

ouf I'm save...

This same issue I faced few days ago. Believe on me their is no need to install or uninstall other dependencies in your project or system.

How I resolve this issue let me share my experience.

• Please go to package.json file
• Scroll down all the below or search for optionalDependencies Object
• Just remove this whole object & save the file
• try npm install, it will work

Please Check out this screenshot of package.json file
