找不到com.android.support:support-v4:23.2.1

Question

当使用react-native 0.28及更高版本(0.29,0.30-rc)时,react-native run-android在新react-native init app项目中执行时会出现以下错误.

Could not find com.android.support:support-v4:23.2.1.

我安装了最新的android工作室,甚至手动安装了过时的库.

我究竟做错了什么？谢谢!

Answer 1

要完成Tonithy的答案 - .jar可能还不够,你需要复制两个完整的目录,否则gradle会抱怨失踪.aar.在这种情况下,我认为这些是由Android Studio安装的: {USER}/Library/Android/sdk/extras/android/m2repository/com/android/support/support-v4/23.2.1/

不要忘记依赖: {USER}/Library/Android/sdk/extras/android/m2repository/com/android/support/support-annotations/23.2.1/

我在升级时遇到了完全相同的问题react-native 0.30,这解决了这个问题.

谷歌似乎已经停止包含每个支持库的版本而没有sources/javadoc/etc,而React正在寻找这个特定的文件.假设您手动安装了过时的版本,那么{YOUR_ANDROID_LOCATION}/extras/android/support/v4/android-support-v4.jar最好将其手动复制到:

cp {YOUR_ANDROID_LOCATION}/extras/android/support/v4/android-support-v4.jar {YOUR_ANDROID_LOCATION}/extras/android/m2repository/com/android/support/support-v4/23.2.1/support-v4-23.2.1.jar

这是一个React Native(版本,可能是OSX特定的bug),很快就会被修复.对于后代,你的完整错误是这样的,在所有错误的地方寻找支持:
