我不明白哪里出了问题。我该如何解决？与同时包含在开发和生产中的行有关吗？

运行npm run dev时，我得到：

sh: cross-env: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! whisper-chat-example@1.0.0 dev: `cross-env NODE_ENV=development webpack-dev-server --hot`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the whisper-chat-example@1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

如错误所述，您已经在dev和production依赖项中定义了程序包。

如果只需要在开发中使用该程序包，则只能在dev依赖项中对其进行定义。如果在生产中需要，则将其从devDependencies中删除，并仅在dependecies中对其进行定义。

关于cross-env，您需要使用npm install cross-env -g将其作为全局软件包安装。这样，命令将被识别并且不会返回错误。

作为开发和生产依赖项而包含的npm安装错误
