我无法运行react项目，npm安装也不起作用

Question

如果npm安装，我会收到以下错误

​

我也尝试过像这样清理缓存

​

如果我直接运行这个项目，它显示的是react，它显示的是“react脚本”不被识别为内部或外部命令。

​

​

这是我的项目中使用的package.json代码，我不知道问题是什么，因为我对react.let来说还是新手，我知道如何运行这个项目。提前谢谢..。

您看到的试图运行构建的错误消息是有意义的。如果尚未首先安装依赖项，则无法运行build脚本--因为您还没有编译项目所需的库！npm run build是根据package.json文件" react -scripts build“的同义词，因此您需要作出反应(这是依赖列表的一部分)。您必须先解决依赖冲突，然后才能运行构建。

npm所依赖的冲突信息告诉您解决这些冲突的步骤，阅读并遵循这些步骤。在尝试了这些官方步骤之后，如果它们没有帮助的话，作为最后的手段，我将尝试手动升级自动重定位器为v10.0.2~似乎您在开发过程中手动安装了它，而不知道顺风会在内部使用它。

希望这能有所帮助。
