上面写着 build.gradle 文件的第 22 行，如下所示：

apply plugin: 'com.android.library'

欢迎提出任何建议！谢谢！

Answer 1

您需要将 Gradle 版本升级到 5.1.1

在android/gradle/wrapper/gradle-wrapper.properties

改变

distributionUrl=https://services.gradle.org/distributions/gradle-4.10.2-all.zip

到

distributionUrl=https://services.gradle.org/distributions/gradle-5.1.1-all.zip

在android/build.gradle 在 buildscript --> 依赖项 下，更改，

类路径'com.android.tools.build:gradle:3.3.2'

到

类路径'com.android.tools.build:gradle:5.1.1'

然后再试一次。
