从一个react项目切换到另一个项目后，npm start抛出错误：系统找不到指定的路径。npm错误！代码ELIFECYCLE

Question

嘿，伙计们觉得这个地方很可能能帮到我。所以我有两个反应项目A和B

每当我运行项目B，然后完成并尝试运行项目A(npm start)，我就会得到错误react-scriptserror。

此外，它只发生在项目A，项目B可以重新运行多次，我想没有错误。

我得到以下错误：

$ npm start

> react-only-template@0.1.0 start E:\projects\project-a
> react-scripts start

The system cannot find the path specified.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! react-only-template@0.1.0 start: `react-scripts start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the react-only-template@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

节点版本10.24.0NPM:6.14.11

同样，react脚本也不是全局安装的！

项目A：CRA是应用程序吗

"react": "^17.0.1",
"react-scripts": "^4.0.0",

项目B：也是CRA app

"react": "^16.13.1",
"react-scripts": "^3.4.3",

我能再次运行project A的唯一方法是，如果我重新启动我的PC机，这真的真的很紧张，因为我必须重新运行docker和很多其他应用程序。我将非常感谢任何人，谁有任何建议，如何解决这个永久或至少使它，使我不必重新启动我的计算机

这种事总是发生的。您是否尝试删除node_moduled,package-lock.json并运行此命令？NPM缓存清理--强制
