NPM：找不到模块“../lib/utils/unsupported.js”

Question

I'm getting the following error when trying to do anything with npm:

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module '../lib/utils/unsupported.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15)

    at tryModuleLoad (internal/modules/cjs/loader.js:593:12)

I can't run npx create-react-app or any npm commands including uninstalling or updating npm. Yesterday I installed yarn , could that be part of the problem? I also updated my Mac to Catalina 10.15.5 recently. I'm not sure if either/both of these caused the npm issue or not.

What's causing this and how can I fix it?

Found a solution. A modified version of this answer worked.

I ran:

brew uninstall --force node

sudo rm -r /usr/local/lib/node_modules

brew install node

and that did the trick.
