Question

在我不得不重新安装计算机上的所有内容之前，项目运行正常。我先运行npm install然后运行expo start

，会收到以下错误

internal/modules/cjs/loader.js:296
      throw err;
      ^

这是我的package.json

Answer 1

安装此软件包。

npm i @react-native-community/cli

Answer 2

使用npm install @ react-native-community-cli并再次运行，否则删除package-lock.json和node_modules，再次安装npm，请在运行项目之前先进行清理

Answer 3

删除了package-lock.json和node_modules，然后重新运行npm install，现在可以正常使用了。

Answer 4

尝试删除 node_modules/ 然后运行 npm install

Answer 5

免责声明：可能偏离主题，与 AppCenter 问题相关

如果您在 App Center 构建中遇到错误 Error: Cannot find module '/node_modules/react-native/local-cli/cli.js'，那么您需要：

从您的 @react-native-community/cli 中删除 package.json
删除package-lock.json并运行npm i（或rm -rf yarn-lock.json && yarn）
将更改推送到分支并运行 App Center 构建

希望它会帮助某人，因为我没有找到解决该问题的任何方法
