国人的博客写的比较懒，个人从stack
over  flow 查找到这个问题，大概就是....

I‘m using npm install [email protected] --save to upgrade React Native, but I keep getting an error that I have an "UNMET PEER DEPENDENCY [email protected]".

This confuses me because I thought I had just installed [email protected]

 

Those error messages can be really poorly worded. I‘ve seen this same thing; it‘s reporting that you have [email protected] installed, but something else is requesting a different version.

I‘d suggest doing an npm ls; it will give you a better picture of all the peer dependency requirements and what‘s wrong.

 

Thanks, I‘ve tried npm ls, and it appears that I have two conflicting requirements: one for [email protected]^0.33.0 and another for [email protected]>=0.40. Is there any way this can be resolved? – user2421192 Jan 8 at 6:58
	Ouch. Unfortunately, I don‘t think you have a good way to resolve that short of finding dependencies that have compatible react-native dependencies. – Jacob Jan 8 at 6:59
