npm install is giving so many errors-CodePudding

I have installed windows 11 in my newly bought laptop, and installed Nodejs, Angular Cli, but when I run npm install in my project everything is giving error, I tried a lot , but could not solve it.

upgrade downgrade node. update all node packages. clear cache etc.

Note:

node version: v16.13.0
npm version: 8.1.4
angular cli version: Angular CLI: 10.1.7

tried all these, but could not solve it.

help me with step by step solutions.

CodePudding user response：

How much more clear can npm be?!

Error: not found: c:\python27\python.exe

some packages require python2.7; others look for python and will accept Python 3. It's a pain; especially for those of us that don't use Python otherwise. But your problem is basic - install Python and try again

CodePudding user response：

This is related to version mismatch between node.js and node-sass in package.json. You can check here all supported versions. https://github.com/sass/node-sass

You will either need to change node.js or node-sass version and do npm install again.
