android - react-native 链接导致 Android settings.gradle 中的重复导入

Question

出于某种原因，当我调用 react-native link , 它将重复包含添加到 android/settings.gradle这又将重复导入添加到 android/app/src/main/com/<projectName>/MainApplication.java .

它并不总是这样做。当我手动添加一个特定的包时它开始这样做，因为有些东西不起作用，但我不记得是哪个。

我的直觉是react-native link假定包以某种顺序列出——它看起来像反向字母顺序——但由于 npm 包名称不一定与 settings.gradle 中的包含项目名称匹配这与 MainApplication.java 中的导入名称不匹配, 我很难弄清楚如何在 settings.gradle 中重新排序它们为了阻止这种行为。或者它可能完全是其他东西。

package.json

{
  // ...
  "dependencies": {
    "events": "^1.1.1",
    "flux": "^3.1.2",
    "react": "~15.4.1",
    "react-native": "0.42.0",
    "react-native-datepicker": "^1.4.4",
    "react-native-fs": "^2.1.0-rc.1",
    "react-native-navigation": "^1.0.30",
    "react-native-push-notification": "^2.2.1",
    "react-native-sound": "^0.9.1",
    "react-native-vector-icons": "^4.0.0",
    "redux": "^3.6.0"
  },
  "devDependencies": {
    "babel-jest": "19.0.0",
    "babel-preset-react-native": "1.9.1",
    "jest": "19.0.2",
    "react-test-renderer": "~15.4.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

文件应该是这样的...

android/settings.gradle

rootProject.name = // <projectName>
include ':react-native-vector-icons'
project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')
include ':react-native-sound'
project(':react-native-sound').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-sound/android')
include ':react-native-push-notification'
project(':react-native-push-notification').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-push-notification/android')
include ':react-native-navigation'
project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/android/app')
include ':react-native-fs'
project(':react-native-fs').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fs/android')

include ':app'

android/app/src/main/com/[项目名称]/MainApplication.java

package // com.<projectName>;

import android.app.Application;

import com.facebook.react.ReactApplication;
import com.oblador.vectoricons.VectorIconsPackage;
import com.zmxv.RNSound.RNSoundPackage;
import com.dieam.reactnativepushnotification.ReactNativePushNotificationPackage;
import com.reactnativenavigation.RnnPackage;

import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.shell.MainReactPackage;
import com.facebook.soloader.SoLoader;

import java.util.Arrays;
import java.util.List;

public class MainApplication extends Application implements ReactApplication {

  private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
            new VectorIconsPackage(),
            new RNSoundPackage(),
            new ReactNativePushNotificationPackage(),
            new RnnPackage(),
            new RNFSPackage(),
      );
    }
  };

  @Override
  public ReactNativeHost getReactNativeHost() {
    return mReactNativeHost;
  }

  @Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
  }
}

在我运行 react-native link 之后，文件更改为:

android/settings.gradle

rootProject.name = // <projectName>

project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')

project(':react-native-sound').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-sound/android')
include ':react-native-push-notification'
project(':react-native-push-notification').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-push-notification/android')
include ':react-native-navigation'
project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/android/app')
include ':react-native-fs'
project(':react-native-fs').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fs/android')
include ':react-native-vector-icons'
project(':react-native-vector-icons').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')
include ':react-native-sound'
project(':react-native-sound').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-sound/android')
include ':react-native-push-notification'
project(':react-native-push-notification').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-push-notification/android')
include ':react-native-navigation'
project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/android/app')
include ':react-native-fs'
project(':react-native-fs').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fs/android')

include ':app'

如果我运行 react-native-link再次，它添加了包的第三个副本。

有没有人知道如何react-native link有用吗？

这是 React Native 上的一个已知错误。目前有一个 PR 正在等待此错误:https://github.com/facebook/react-native/pull/18131

更新:错误已修复!

要解决此问题，您只需在运行 react-native-link 时手动梳理依赖项。我发现在运行它之前拥有一个干净的 git status 是很有帮助的，然后在之后使用 git diff 检查更改的文件。
