react-native版本0.81，create-react-native-library版本0.54.3
按照官方文件执行

npx create-react-native-library@latest --local

执行完成后，直接运行项目会报错

The NODE_ENV environment variable is required but was not specified. Ensure the project is bundled with Expo CLI or NODE_ENV is set. Using only .env.local and .env

解决方案

1.在module.kt文件中添加代码

import com.facebook.fbreact.specs.NativeTestModuleSpec

2.在module.kt中添加代码并配置模块中的package.json

import com.testmodule.NativeTestModuleSpec

"codegenConfig": {
    "name": "TestModuleSpec",
    "type": "modules",
    "jsSrcsDir": "src",
    "android": {
       // 这里指定java包名
       "javaPackageName": "com.testmodule"
     }
  },
