npm-consider fails on "Impact"

[Themayu]

The issue is exactly as the title says: npm-consider seems to fail when selecting Impact. Associated command output with stack trace is below (tested using express with command npm-consider install --save express):

Note that this error also occurs if I attempt to use the module directly in the Windows command prompt.

Edit: accidentally hit CTRL+ENTER while writing, then realised what I was typing didn't even matter anyway so I removed it.

Just got the same error, it seems, on macOS. The following is what I tried exactly:

$ npm install -g npm-consider
/Users/xxx/.nvm/versions/node/v13.1.0/bin/npm-consider -> /Users/xxx/.nvm/versions/node/v13.1.0/lib/node_modules/npm-consider/bin/npm-consider.js

As this been fixed somehow?

Or maybe someone has any clue on the problem, so I could try and help myself?
