this package swallow errors, undebuggable

[Congrammers]

After installing package, I had problem on running the command, nothing happen, no error, no anything.

I used the code above instead. and then I figured out what's lacking; I need to install multiple npm package which is its dependencies. Now, I get the fixer running.

My only request is for this package to not swallow error.

Would you consider sending a pull request that prints the error message?
