npx fails with "cb.apply is not a function" error

[mssngr]

Current Behavior

 ~ npx tsdx create test
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_09_17_505Z-debug.log
Install for [ 'tsdx@latest' ] failed with code 1

Expected behavior

It to actually create the test library.

Suggested solution(s)

Unsure what the actual problem is.

Additional context

I cleared my npm cache, but I realize, now, that npx doesn't even use my system's npm. It has it's own npm in a bin folder it uses.

Your environment

 ~ npx envinfo --system OS --browsers --binaries --npmPackages tsdx,typescript --npmGlobalPackages tsdx,typescript
npm ERR! cb.apply is not a function

Well, that was unhelpful. Maybe this is an issue with npx, itself? I have also tried reinstalling npx, but I get the same results.

 ~ npx --version

Seems this is an issue solely with npx.
