Can you run react-native info and edit your issue to include these results under the Environment section?

If you believe this information is irrelevant to the reported issue, you may write [skip envinfo] under Environment to let us know.

Yes, I am having the same error.
"ERROR: Could not get unknown property 'mergeResourcesProvider' for object of type com.android.build.gradle.internal.api.ApplicationVariantImpl."

I am also using React Native 0.59.0-rc.1

I am trying to implement React Hooks with React_Native.
Also using Typescript, Win10, I5, 16GB ram, latest versions of node, android studio etc.

Breaks during build following instructions from here: https://facebook.github.io/react-native/docs/getting-started.html

using the Building Projects from Native Code variant.

Error msg reads:

In gradle-wrapper.properties
change distributionUrl to distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip
and in root build.gradle file change gradle classpath to this: classpath 'com.android.tools.build:gradle:3.3.0'

Can't wait for RN 0.59 (with hopefully hooks included ; )!

Edit: Wrote package.json instead of Environment ^^.

It can build package
it's not works on ubuntu 16 dev env, although i can build it but emulator error 500, like this image

[ABQJuan]

@webnah, I'm following Ben's project too. lol. I'm on a Windows 10 machine :( and got the same screen you are showing with the same 500 error code. Frustrating to say the least

I change to macos (PC installed) run-ios and the same error (benawad rnw tutorial) , the problem is they demo state in 0.59.x
anyway: rn 0.58.5 works

[DimitryDushkin]

Same error on run-android with RN 0.59.0-rc.2

I got it running by following the official _Get Started_ guidelines for _Building Projects with Native Code_ Linux / Android - had to downgrade my Java Version to 8 for this to work - and applying @alexandrius "patch" to android/gradle/wrapper/gradle-wrapper.properties - with com.android.tools.build:gradle:3.3.1 instead of 3.3.0 - and android/build.gradle respectively.
My exact package.json is:

{
  "name": "random",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.8.1",
    "react-native": "0.59.0-rc.2"
  },
  "devDependencies": {
    "@types/react": "^16.8.4",
    "@types/react-native": "^0.57.38",
    "babel-core": "^7.0.0-bridge.0",
    "babel-jest": "24.1.0",
    "jest": "24.1.0",
    "metro-react-native-babel-preset": "0.52.0",
    "react-test-renderer": "16.8.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

My package manager is yarn. Have a look at my react-native info in mine last comment for versions used.
Hope it helps anybody struggling : )!

[alexandrius]

There are issues with upgrading RN version. The easiest way to avoid issues is just to compare with "template" from react-native specific version branch. Here's the template from 0.59.0
https://github.com/facebook/react-native/tree/0.59-stable/template

Do cleanup after upgrading version.
rm -rf node_modules/
npm i or just yarn
then start with
react-native start --reset-cache

If you have CocoaPods don't forget to
pod update

[DimitryDushkin]

BTW I resolved issue by setting explicit (downgraded) metro version to 0.51.0: "metro": "0.51.0",

[marcelovicentegc]

It seems that this issue is related to the metro bundler not resolving to the right paths, thus Unable to resolve module...

Executing react-native start on one terminal at the project directory and react-native run-android on another terminal worked for me.

By the way, I got metro version 0.52.0 with react-native 0.59.0-rc.2.

Does it works for anyone else?

[ABQJuan]

@marcelovicentegc it doesn't work for me. I am still getting the Unable to resolve module error. I am on a Windows 10 machine.

[kimbui87]

@webnah @ABQJuan
Copy file 'metro.config.js' in 0.59-stable/template to your project.
Remove node_modules
yarn install
and run-android again.
(And make sure version of metro in package.json "metro-react-native-babel-preset": "0.51.0" is the same with current metro's version)
I solved by above steps

[krrskl]

@webnah The same error was happening to me after applying what @alexandrius indicated. the solution after running react-native run-android was to stop the command after the application was already running in the emulator and then run react-native start and the problem went away.

[shimesami]

After spending so much time.
Downgrading react-native version from 0.59.1 to 0.58.5 did it for me.

[supagu]

@shimesami solution works, downgrading react-native resolves the issue.

I suspect the real problem for me is that react-native-maps needs to be upgraded to uses newer libs?

[PraAnj]

@shimesami solution works for me as well.

paste /* eslint-env node */ at the top of metro.config.js

/* eslint-env node */
/**
 * Metro configuration for React Native
 * https://github.com/facebook/react-native
 *
 * @format
 */
module.exports = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,

    }),
  },
};

I was having similar issues, my antivirus was identifying things as false positive and blocking them. I've changed the antivirus. =P

[Andevelop1234]

In gradle-wrapper.properties
change distributionUrl to distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip
and in root build.gradle file change gradle classpath to this: classpath 'com.android.tools.build:gradle:3.3.0'

Love ya man, thanks!
