Angular-cli: "ng new" throws an error while installing dependencies, dependency "error-ex" not found

[akmalnawfer]

I installed angular 9 cli, my node.js is on latest version. While I try to create a new angular project im getting the following error.

This seems like a problem with your node/npm and not with Angular CLI.

Please have a look at the fixing npm permissions page, common errors page, npm issue tracker, or open a new issue in that issue tracker if the problem you are experiencing isn't known.

Note this line in your log:

npm ERR! 404 Not Found - GET https://registry.npmjs.org/error-ex

Try going to that URL and see if you can access it. For me the request does not 404. If it does then there is some problem with you npm registry connection.

[AbdelAbdelAli]

the request does error 404
i just updated my npm, node and angular cli

[EMProduct]

the url get 404
i installed the npm an angular cli and same problem

as a temporary fix you can manually install "error-ex" module directly from GitHub then install your dependencies as mentioned here https://github.com/facebook/create-react-app/issues/8465#issuecomment-585135338

$ npm i https://github.com/Qix-/node-error-ex
$ npm i

I had a similar problem. It appears to be an npm problem. Then I changed my package manager for Angular by running ng config -g cli.packageManager yarn. I literally shouted, "Thank you Yarn"
