[BUG] cb.apply is not a function

[mssngr]

What / Why

NPX fails with cb.apply is not a function error every single time I try to use npx.

When

• Anytime I try to use NPX
• First noticed after I successfully ran npx create-react-app <project-name> --typescript
• All npx commands afterward failed

Where

• All npm packages

How

Current Behavior

 ~ npx hello-world-npm
npm ERR! cb.apply is not a function

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/p2813835/.npm/_logs/2021-01-14T22_24_12_119Z-debug.log
Install for [ 'hello-world-npm@latest' ] failed with code 1

Reinstalling npx does not solve

Steps to Reproduce

• Unsure. Maybe try to use npx to create a react app with the typescript template?
• Then try to use npx after that?

Expected Behavior

• npx should work

Also, reinstalling with npm globally gives this error?

Those errors are in your npm ls -g, and have nothing to do with npx.

[mssngr]

Ok. You can ignore that, then.

As for the cb.apply is not a function error, I found a workaround:

 ~ npx --npm /usr/local/bin/npm hello-world-npm
npx: installed 1 in 2.554s
Hello World NPM

It seems the npm supplied by npx has issues. Using my system's npm resolves the issues. Why does npx supply its own npm?

[mssngr]

Looks like this would solve it: #70

Issue is that the old version of npm that npx has in its /bin folder is not compatible with the lts version of node. Downgrading my node to node@10.23.1 resolves this issue.

 ~ node --version
v10.23.1                                                                                                                                                                     /0.1s
 ~ npx hello-world-npm
npx: installed 1 in 1.801s
Hello World NPM                                                                                                                                                              /2.0s

This is such a simple issue. Hope that PR gets merged soon (been open for 6 months.)

I downgraded npm to npm@6.14.11 and all is working again.
