Description

According to the react-native CLI documentation we can specify custom configuration based on each platform for RN CLI. I want to change the default location of each platform folders so I added my custom react-native.config.js to the root of the project which you can find that here:

module.exports = {
  project: {
    ios: {
      project: './example/ios/example.xcworkspace',
    },
    android: {
      sourceDir: './example/android/',
    },
  },
};

If I run react-native config in the root folder, I can see the correct configuration:

{
...
  "project": {
    "ios": {
      "sourceDir": "path-to-project-directory/example/ios",
      "folder": "path-to-project-directory",
      "pbxprojPath": "path-to-project-directory/example/ios/example.xcworkspace/project.pbxproj",
      "podfile": "path-to-project-directory/example/ios/Podfile",
      "podspecPath": null,
      "projectPath": "path-to-project-directory/example/ios/example.xcworkspace",
      "projectName": "example.xcworkspace",
      "libraryFolder": "Libraries",
      "sharedLibraries": [],
      "plist": [],
      "scriptPhases": []
    },
    "android": {
      "sourceDir": "path-to-project-directory/example/android/",
      "isFlat": true,
      "folder": "path-to-project-directory",
      "stringsPath": "path-to-project-directory/example/android/app/src/main/res/values/strings.xml",
      "manifestPath": "path-to-project-directory/example/android/app/src/main/AndroidManifest.xml",
      "buildGradlePath": "path-to-project-directory/example/android/build.gradle",
      "settingsGradlePath": "path-to-project-directory/example/android/settings.gradle",
      "assetsPath": "path-to-project-directory/example/android/app/src/main/assets",
      "mainFilePath": "path-to-project-directory/example/android/app/src/main/java/com/example/MainApplication.java",
      "packageName": "com.example",
      "packageFolder": "com/example",
      "appName": "app"
    }
  }
}

The problem is whenever I run react-native run-ios I get this error:

error iOS project folder not found. Are you sure this is a React Native project?. Run CLI with --verbose flag for more details.

NOTE: I installed all the dependencies properly. Here is the result of the react-native --v command:

react-native-cli: 2.0.1
react-native: 0.62.0

Reproducible Demo

1. Create a RN project via react-native init
2. Create a subfolder in the project and move ios and android folders there
3. Create a react-native.config.js in the root directory and export project configuration as I provided in this issue(You can find in the Description section).
4. Try to run the project via react-native run-ios or react-native run-android

I'm having the same issue on iOS. Got it working by specifying the project-path: react-native run-ios --project-path example/ios. But I feel this shouldn't be needed?

module.exports = {
  project: {
    android: {
      sourceDir: './example/android',
    },
    ios: {
      project: './example/ios/example.xcodeproj',
    },
  },
};

[jenshandersson]

Looking at the code it looks like react-native.config.js is being ignored for iOS. The script simply looks for project/workspace in the root or --project-path.

cli/packages/platform-ios/src/commands/runIOS/index.ts

Line 52 in 4870ac5

const xcodeProject = findXcodeProject(fs.readdirSync('.'));

Oh we should fix that. Would you like to contribute @jenshandersson? cc @grabbou

[hamidhadi]

Thanks @jenshandersson 👍
What about Android? 🤔
It seems Android has the same issue. It gets AppFolder from args

cli/packages/platform-android/src/commands/runAndroid/index.ts

Line 127 in 4870ac5

const {appFolder} = args;

[jenshandersson]

@hamidhadi Android works fine for me. I think the args come from the react-native.config.js in this case.

cli/packages/cli/src/index.ts

Line 136 in 9e44835

const passedOptions = this.opts();

[hamidhadi]

@jenshandersson Strange! I have this issue with Android as well!

[thymikee]

@hamidhadi make sure you're on the latest version of the @react-native-community/cli.

Any updates on this bug? I've searched everywhere about how to not have to copy/paste my project into the "android" folder and instead tell the react-native module to look into a different directory instead. I also tried the same approach as the author and ran into the exact same error hmm..

[gaoxianglyx]

the same error in android for me
android studio sync error,

[ghasemikasra39]

same issue on android, any solution?

[ardagoc]

still same on android

[Easy-Ez]

hi guy, is there a solution?

[yatessss]

same issue

[yashNiflr]

same issue on ios

Steps to run the app from custom dir:

Imagine you have file structure like below:

Then you have to take those steps to have working iOS and Android Apps:

• specify custom sourceDir in react-native.config.js:

module.exports = {
  project: {
    ios: {
      sourceDir: 'example',
    },
    android: {
      sourceDir: 'example/android/',
    },
  },
};

Adjust paths for node_modules like so:

iOS:

• in Podfile change require_relative:

+ require_relative '../../node_modules/react-native/scripts/react_native_pods'
- require_relative '../node_modules/react-native/scripts/react_native_pods'
+ require_relative '../../node_modules/@react-native-community/cli-platform-ios/native_modules'
- require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

• change Bundle React Native code and images shell script:

- shellScript = "set -e\n\nWITH_ENVIRONMENT=\"../node_modules/react-native/scripts/xcode/with-environment.sh\"\nREACT_NATIVE_XCODE=\"../node_modules/react-native/scripts/react-native-xcode.sh\"\n\n/bin/sh -c \"$WITH_ENVIRONMENT $REACT_NATIVE_XCODE\"\n";
+ shellScript = "set -e\n\nWITH_ENVIRONMENT=\"../../node_modules/react-native/scripts/xcode/with-environment.sh\"\nREACT_NATIVE_XCODE=\"../../node_modules/react-native/scripts/react-native-xcode.sh\"\n\n/bin/sh -c \"$WITH_ENVIRONMENT $REACT_NATIVE_XCODE\"\n";

• change "Start Packager" shell script:

- echo "export RCT_METRO_PORT=${RCT_METRO_PORT}" > "${SRCROOT}/../../node_modules/react-native/scripts/.packager.env"
+ echo "export RCT_METRO_PORT=${RCT_METRO_PORT}" > "${SRCROOT}/../node_modules/react-native/scripts/.packager.env"
// ...
- open "$SRCROOT/../node_modules/react-native/scripts/launchPackager.command" || echo "Can't start packager automatically"
+ open "$SRCROOT/../../node_modules/react-native/scripts/launchPackager.command" || echo "Can't start packager automatically"

(remember to run bundle exec pod install command when you're done 😉 )

Android:

• in settings.gradle file:

- apply from: file("../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesSettingsGradle(settings)
include ':app'
- includeBuild('../node_modules/react-native-gradle-plugin')
+ apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesSettingsGradle(settings)
include ':app'
+ includeBuild('../../node_modules/react-native-gradle-plugin')

• in app/build.grade:

project.ext.react = [
    enableHermes: true,  // clean and rebuild if changing
+    cliPath: "../../../node_modules/react-native/local-cli/cli.js",
]
- apply from: "../../node_modules/react-native/react.gradle"
+ apply from: "../../../node_modules/react-native/react.gradle"
// ...
- apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)
+ apply from: file("../../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)

• in build.grade:

repositories {
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
-            url("$rootDir/../node_modules/react-native/android")
+            url("$rootDir/../../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
-           url("$rootDir/../node_modules/jsc-android/dist")
+           url("$rootDir/../../node_modules/jsc-android/dist")
        }

Similar adjustments have to be made for new architecture blocks in mentioned files.
