Not able to install alias library

What I Wanted to Do

I want to install alias and babel-eslint library

What Happened Instead

babel-eslint failed as there was no dependent library "alias " found. Error: “Invalid dependency type requested: alias”

I tried installing alias library separately, then got following error,
npm ERR! typeerror Error: Argument #2: Expected string but got null

Reproduction Steps

  1. run “npm i alias”
  2. observe the error displayed


Following error is displayed,

(I think this is probably a problem package rather than an npm bug as such, moved topic to #support.)

I do not think the error you got when installing babel-eslint was referring to the alias package, I think it was referring to some text in the package.json.

Possibly because the package has been set up for yarn according to this post:

I was able to install babel-eslint without issue in a fresh project on Mac.

Thanks for the reply shadowspawn (y)

I will try again for babel-eslint, but I confirm, there is a no mention of alias in package.json file for babel-eslint library. That’s why it puzzled me and just with trial and error, I end up downloading alias library.
