android - react-native android-run 失败(全新安装)

Question

这是我的步骤:

react-native 初始化应用

cd 应用程序

react-native run-android

A problem occurred configuring project ':app'. java.lang.NullPointerException (no error message)`

cd android && ./gradlew installDebug --info

Parsing /Users/xxxx/Library/Android/sdk/tools/package.xml

file or directory '/Users/xxxx/Projects/personal/app/android/app/libs', not found

file or directory '/Users/xxxx/Projects/personal/app/android/app/libs', not found

file or directory '/Users/xxxx/Projects/personal/app/android/app/libs', not found

file or directory '/Users/xxxx/Projects/personal/app/android/app/libs', not found

Using incremental javac compilation.

Incremental java compilation is an incubating feature.

FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring project ':app'. java.lang.NullPointerException (no error message)

我不知道这里有什么问题。为什么 gradle 正在寻找一个不存在的库？为什么 react-native 不创建这个目录？

对于遇到此问题的任何人 - 对我来说，这是因为 SDK 路径在流程的某些部分不起作用。我有export ANDROID_HOME="~/Library/Android/sdk/"这失败了，而 export ANDROID_HOME="/Users/username/Library/Android/sdk/" 工作正常。
