无法在Android设备上构建react-native应用程序:找不到带有哈希字符串"android-23"的目标

这是完整的错误:failed to find target with hash string 'android-23' in: /Users/username/Library/Android/sdk

Here is the full error: failed to find target with hash string 'android-23' in: /Users/username/Library/Android/sdk

这是我的android/app中的build.gradle文件:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.mobile"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

我运行了Android SDK Manager，并且安装了Android SDK Build-Tools Rev 23.0.1，以及所有适用于Android 6.0(API 23)的文件.

I ran the Android SDK Manager, and I have the Android SDK Build-Tools Rev 23.0.1 installed, along with all the files for Android 6.0 (API 23).

我在网上搜索了此问题，并尝试了许多解决方案；重新启动终端，删除根目录中的gradle文件，确保ANDROID_HOME指向正确的目录(当我关注ReactNative文档时，我在~./bashrc和~./bash_profile中都复制了以下行: # If you installed the SDK via Homebrew, otherwise ~/Library/Android/sdk export ANDROID_HOME=/usr/local/opt/android-sdk.

I searched online for this problem and have tried many solutions; restarting the terminal, deleting the gradle file in the root directory, making sure ANDROID_HOME points to the correct directory (As I am following the ReactNative docs, I have copied in both ~./bashrc and ~./bash_profile the following line: # If you installed the SDK via Homebrew, otherwise ~/Library/Android/sdk export ANDROID_HOME=/usr/local/opt/android-sdk.

到目前为止，对我来说什么都没有用，而且我不断遇到同样的错误. 我应该补充说，在安装Android Studio之前一切正常，然后开始出现此错误.从那以后，我天真地卸载了Android Studio，以为它可以解决问题.

Nothing has worked for me so far and I keep getting the same error. I should add that everything was working fine until I installed Android Studio, after which point I started getting this error. I have since then uninstalled Android Studio naively thinking it would solve the problem.

请帮助我，你是我唯一的希望.

Please help me SO, you're my only hope.
