安装React Navigation和手势处理程序后出现错误

Question

我是React-native的新手，并尝试使用Windows版Android Studio中的本地本机构建android应用。安装react-navigation后，请按照react-navigation文档中的所有步骤操作，运行react-native run-android，然后在命令行中收到此错误：

PS C:\Users\comp\Desktop\work\reactnative\dansapp> react-native run-android
Starting JS server...
Building and installing the app on the device (cd android && gradlew.bat installDebug)...

FAILURE: Build failed with an exception.

* Where:
Settings file 'C:\Users\comp\Desktop\work\reactnative\dansapp\android\settings.gradle' line: 3

* What went wrong:
Could not compile settings file 'C:\Users\comp\Desktop\work\reactnative\dansapp\android\settings.gradle'.
> startup failed:
  settings file 'C:\Users\comp\Desktop\work\reactnative\dansapp\android\settings.gradle': 3: unexpected char:

     s\react-native-gesture-handler\android')
                                   ^

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

有人知道这个错误是什么以及如何解决？按照以下步骤安装react-navigation之后，似乎会发生这种情况：https://reactnavigation.org/docs/en/getting-started.html

我遵循了这些步骤，包括更改mainActivity.java文件。我也不知道gradle是什么。

任何帮助将不胜感激！

Answer 1

已知issue（请参阅：bug with react-native link in android and windows），希望很快会修复。

跳转到/ dansapp / android /中的settings.gradle文件，然后替换...

project(':react-native-gesture-handler').projectDir = new File(rootProject.projectDir, '..\node_modules\react-native-gesture-handler\android')

...与...

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

Answer 2

FAILURE：构建因异常而失败。

• 其中：设置文件'E：\ RN \ sc3 \ android \ settings.gradle'行：4

• 出了什么问题：无法编译设置文件'E：\ RN \ sc3 \ android \ settings.gradle'。

  启动失败：设置文件'E：\ RN \ sc3 \ android \ settings.gradle'：4：意外的字符：'\'@第4行，第133列。s \ react-native-gesture-handler \ android'）^可以解决plaese！
