尝试使用 android 运行我的 react-native 应用程序时出现以下错误，我不确定为什么，有什么想法吗？

*哪里：构建文件 '/Users/ahmeeyagoldman/Documents/TikTok/android/app/build.gradle' 行：123

出了什么问题：评估项目“:app”时出现问题。

无方法签名：build_26i9j525hbm41pwpexiy08g68.android() 适用于参数类型：(build_26i9j525hbm41pwpexiy08g68$_run_closure1) 值：[build_26i9j525hbm@6ee_8g68fcclosure1] 我的 build.gradle 文件：

到目前为止，我已经尝试过：

升级和降级我的gradle， -清理并重建项目， - 使缓存无效/重新启动， - 注释掉新的代码行，
编辑我的配置（没有太大变化）

如果我尝试另一个项目，我可以使用 react-native 运行一个 android 应用程序，但这个项目抛出错误。需要注意的事情我不确定这是否重要，但这与 AWS 相关。

 * bundle directly from the development server. Below you can see all the possible configurations

解决方法

错误是在“multidexEnabled true”中发现的，它应该是“multiDexEnabled true”，Dex中的大写字母D。

如果有人再次遇到同样的错误，我建议您开始注释掉属于 android 的每一行代码，直到找到错误为止。

该错误只是指您代码中的某些语法错误，这些错误可能会延迟其他人的程序，并具有相同的错误响应。
