Running against .ts files fails with error: 'TypeError: p is not iterable' #688
Description
Bug Description
I'm trying to run depcheck against TypeScript code but it's failing with the error: TypeError: p is not iterable. I've tried installing with npm i -g depcheck and also npm i -g depcheck typescript.
The error was generated after running:
depcheck path/to/my/repo --json
I have tried:
depcheck path/to/my/repo --parsers="*.ts" --json
However, when I run this (^) command I get the error: Cannot read property 'split' of undefined. It does seem to be working as expected for .js files though.
Here's the stack trace for the error in the issue title.
