React Native Android 打包出错 Could not get unknown property 'MYAPP_RELEASE_STORE_FILE'

今天从同事那里拷贝了一个 React Native 项目，打包的时候出错了，错误信息如下

Build file '/Users/yufei/Downloads/xxx/android/app/build.gradle' line: 202

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not get unknown property 'MYAPP_RELEASE_STORE_FILE' for SigningConfig_Decorated{name=release, storeFile=null, storePassword=null, keyAlias=null, keyPassword=null, storeType=jks, v1SigningEnabled=true, v2SigningEnabled=true} of type com.android.build.gradle.internal.dsl.SigningConfig.

原因是打包的签名文件配置没找到，修复方法就是使用 keytool 重新生成一个（或者你已经生成了）然后修改

android/gradle.properties

文件添加以下属性

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=123456
MYAPP_RELEASE_KEY_PASSWORD=123456

具体的属性值要按照你的来
