未计算文件的 React-Native Bundle Error 错误 SHA-1

Question

我在创建 react-native 应用程序包时遇到了这个错误。

我正在执行命令 react-native bundle –dev false –entry-file index.js –bundle-output ios/main.jsbundle –platform ios

 error SHA-1 for file /usr/local/lib/node_modules/react-native/node_modules/metro/src/lib/polyfills/require.js (/usr/local/lib/node_modules/react-native/node_modules/metro/src/lib/polyfills/require.js) is not computed. Run CLI with --verbose flag for more details.

Answer 1

为了解决我的问题，我使用 –force 选项运行命令。

npm install -i -g –force react-native-cli

由于使用旧的 react-native 版本配置旧项目而引发了此问题。然后尝试使用新项目运行最新的 react-native ver。

我认为这是关于 react-native-cli 的版本。

你应该尝试更新。

 npm i -g react-native-cli
