在你的项目目录中有一个名为“android”的文件夹,其中有一个本地。属性文件。 删除该文件,构建应该会成功运行

您可以尝试添加ANDROID_PATH
export ANDROID_HOME=/Users/<username>/Library/Android/sdk/
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
我能找到的最佳解决方案如下:
Download Android Studio and SDK of your choice (Even if you think you don't need it trust me that you would need it to release the apk file and some manual changes to the android code). File > New > Import , point to the location where your react native android project is. If it ask you to download any specific SDK then please download the same. It can ask you to update gradle etc... Please keep on updating where required. If you have an existing Android SDK and you know the version then all you have to do is match that version under build.gradle of your android project.
这是gradle文件看起来的样子:
如果你的机器设置一切顺利,你可以使用Android Studio编译项目,那么没有什么会阻止你通过react-native cli build Android命令构建你的应用程序。
使用这种方法,您不仅可以解决SDK的问题,还可以解决与Android开发的机器设置相关的许多问题。导入将自动找到SDK位置并创建local.properties。因此,您不需要担心人工干预。
转到react-native项目的android/目录 创建一个名为local的文件。这一行的属性:
sdk.dir = /Users/USERNAME/Library/Android/sdk
USERNAME是你的macOS用户名
这对我来说很有效:如果你安装了Android Studio,你可以在Android Studio中打开项目的Android文件夹。当地的。当Android Studio打开该文件夹时,会自动创建properties文件,您的项目应该在此之后构建。
Open Android Studio 点击“打开现有项目” 在项目文件夹中选择“android”文件夹 按“打开”
我认为不建议更新本地。属性文件获取,以添加缺失的环境变量。
更新环境变量:

sdk可以安装在/Library/Android/sdk或/usr/local/以确保检查它
which sdkmanager
出口ANDROID_HOME
export ANDROID_HOME=$HOME/Library/Android/sdk
or
export ANDROID_HOME="/usr/local/share/android-sdk"
然后将其添加到$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/build-tools/28.0.1:$PATH
android-23
export ANT_HOME=/usr/local/opt/ant
export MAVEN_HOME=/usr/local/opt/maven
export GRADLE_HOME=/usr/local/opt/gradle
export ANDROID_HOME=/usr/local/share/android-sdk
export ANDROID_SDK_ROOT=/usr/local/share/android-sdk
export ANDROID_NDK_HOME=/usr/local/share/android-ndk
export INTEL_HAXM_HOME=/usr/local/Caskroom/intel-haxm
