iOS Question

Unable to resolve module react/lib/ReactUpdates

I'm cloning a proyect:

The steps are:


  • npm i

  • react-native link



When i run it
react-native run-ios
i have a problem with
RCTWebSocket
library. This problem is easy to resolve if you search a little just need remove 2 compiler flags, in
Custom Compiler Flags
.

Later just i run again
react-native run-ios
and works fine, but when the app is open, show the next error:

enter image description here

Searching i found that is related to
upgrade
, source here

but i'm using that command and not works.


When this command is executed, it starts showing me some overrides to some files and at the end of this process, the problem persists.


My react info:

react-native-cli: 1.0.0
react-native: 0.32.1


I'm running in
Xcode 8
and ios
10.0



PDTA: When I start a new project works perfect


UPDATES:

When clone on another mac works, I am ensuring to have the same versions of both xcode and node.

Could it be some mac configuration problem?

The only difference between the 2 macs is the cli version:

`react-native-cli: 1.1.0` --> my mac
`react-native-cli: 1.2.0` --> the other mac


Will this be enough to cause all this problem?

Answer

The problem is most likely that you are using React 15.4.x instead of 15.3.x. One of the changes between 15.3 and 15.4 was that many of the modules under react/lib were moved to react-dom/lib, which is why the packager can't find react/lib/ReactUpdates.

Ensure that your package.json file locks React to 15.3.x:

"dependencies": {
  "react": "~15.3.2"
}

Then delete your node_modules folder and run yarn or npm install again. Verify that you installed React 15.3.x:

$ npm ls react
app@1.0.0 /code/app
└── react@15.3.2

Last, restart the React Native server and load your bundle again.
