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，在新的react-native run-android项目中执行react-native init app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。

我做错了什么？ 谢谢！

Answer 1

要完成Tonithy的回答 - .jar可能还不够，你需要复制两个完整的目录，否则gradle会抱怨丢失的.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/

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

升级到react-native 0.30时我遇到了完全相同的问题，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，它将在{YOUR_ANDROID_LOCATION}/extras/android/support/v4/android-support-v4.jar中。您最好的选择是手动将其复制到：

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：

Answer 3

我也遇到了这个错误，安装Android支持库后错误消失了。 从Extras安装Android支持库

Answer 4

第一个解决方案可能是添加此

    compile 'com.android.tools:sdklib:23.2.1'

到下一个文件

  

机器人/应用/的build.gradle

第二个解决方案是安装 Android支持存储库

Answer 5

完成Tonithy和Simon的回答，是的，jar本身还不够，两个目录的所有文件 -
    extras/android/m2repository/com/android/support/support-v4/23.2.1/和    需要extras/android/m2repository/com/android/support/support-annotations/23.2.1/。在我的Windows PC上，我无法在任何地方找到这些目录的文件。

所以我做的是，我从googlesource

下载了这些文件夹

<强> 1。 support/support-annotations/23.2.1

下载上述文件夹的tgz并将文件解压缩到{YOUR_ANDROID_LOCATION}/extras/android/m2repository/com/android/support/support-annotations/23.2.1/

<强> 2。 support/support-v4/23.2.1

下载上述文件夹的tgz并将文件解压缩到{YOUR_ANDROID_LOCATION}/extras/android/m2repository/com/android/support/support-v4/23.2.1/

现在转到命令propmt或终端并运行react-native run-android

希望能节省几个小时!!
