crashes on iOS launch: "undefined is not an object"

[lurui1029]

*the iOS release-mode app crashes at launch time if anywhere in code is importing 'react-native-svg'.
*Using:
React Native 0.50.2
react-native-svg 5.5.1
*The console error message: "undefined is not an object"

It turns out to be a problem related to color, color-string, color-convert.
Here's a similar issue: GeekyAnts/NativeBase#1348

Do you have anything more from the stack trace? Is this causing an RSOD? Also, have you tried upgrading to 6.0.x?

I believe it is not a problem of react-native-svg. It worked nice after I upgraded some of the packages in node_modules. Specifically, "color_converter" and "metro-bundler". The issue is now closed!
