NPM is failing to install any scoped packages

Question

I'm on Node v6.10.3 and NPM v3.8.6.

My issue is that I'm unable to install any scoped packages. Everything returns with a 404 Not Found.

Here's some examples to list:

24 silly fetchPackageMetaData Error: Registry returned 404 for GET on http://registry.npmjs.org/@types%2fjasmine

So far, I've tried setting a registry on the scope (as shown below), changing npm versions, clearing the cache, and deleting the node modules.

npm config set @types:registry http://registry.npmjs.org/

So far nothing has worked. I feel like it may be some kind of encoding issue that occurs when npm tries to access scoped packages. I'm still able to install all unscoped packages.

Another thing, I've noticed is that this issue only occurs on the npmjs registry. I have another scoped registry set up for @progress (https://registry.npmjs.telerik.org), and I'm actually able to install packages from there.

Any advice or tip would be appreciated.

Answer 1

Found out this was caused by my Company's proxy.

The redirection causes the escaped '/' to become un-escaped, so it was hitting https://registry.npmjs.org/@angular/core rather than https://registry.npmjs.org/@angular%2fcore
