react-native link occasionally errs with "str.replace is not a function", no way to debug

[j2kun]

Description

I have an xcode workspace set up with nonstandard configurations, and adding a new react-native ios dependency sometimes fails with str.replace is not a function. I have no idea how to debug this, as the linking command doesn't provide a --verbose option, or anything similar.

E.g.

react-native link react-native-image-crop-picker
rnpm-install info Android module react-native-image-crop-picker is already linked 
rnpm-install info Linking react-native-image-crop-picker ios dependency 
rnpm-install ERR! It seems something went wrong while linking. Error: str.replace is not a function 
Please file an issue here: https://github.com/facebook/react-native/issues 

str.replace is not a function

I cannot reproduce this issue from a fresh project install, and I have no idea where to look for the problem.

react-native-cli: 2.0.1
react-native: 0.40.0

I fixed one instance of this type of error in #13373 where .replace was called on packageName when it can be undefined.

If you want to dig into the source of an error in link you can dump the error to the console from here:

react-native/local-cli/link/link.js

Lines 176 to 182 in 0a712f5

	return promiseWaterfall(tasks).catch(err => {
	log.error(
	`Something went wrong while linking. Error: ${err.message} \n` +
	'Please file an issue here: https://github.com/facebook/react-native/issues'
	);
	throw err;
	});
