Here is the full error, which appears to happen upon using any npm install command:

npm error code ETARGET
npm error notarget No matching version found for @types/react-icons@^5.0.1.       
npm error notarget In most cases you or one of your dependencies are requesting   
npm error notarget a package version that doesn't exist.
npm error A complete log of this run can be found in: <...>

I have tried just about every solution from this similar post:
Npm Error – No matching version found for. However, I’m still running into this error.

The npm cache clean --force command in particular seems to be a popular solution across multiple similar posts, but it doesn’t fix anything for me.

Using npm view react-icons versions, I can see that react-icons version 5.0.1 exists, so what is going on?

I’m a beginner, so I’m really lost here. Let me know if more information is needed.
