javascript - 在React应用程序中运行npm start之后，我遇到了这个错误: internal/modules/cjs/loader.js:834

Question

我下载了我的类(class)react项目，进入了该项目，安装了依赖项，并尝试运行npm start。我收到这个讨厌的错误:

PS C:\Users\Marcin & Joanna\Desktop\react-frontend-01-starting-setup> npm start

> frontend@0.1.0 start C:\Users\Marcin & Joanna\Desktop\react-frontend-01-starting-setup
> react-scripts start

'Joanna\Desktop\react-frontend-01-starting-setup\node_modules\.bin\' is not recognized as an internal or external command,
operable program or batch file.
internal/modules/cjs/loader.js:834
  throw err;
  ^

我尝试与其他项目，相同的结果。
我尝试运行npx-create-react-app my-app失败，但出现此错误:

PS C:\Users\Marcin & Joanna\Desktop\mernStack> npx create-react-app frontend
Error: EPERM: operation not permitted, mkdir 'C:\Users\Marcin'
System nie może odnaleźć określonej ścieżki.
Instalacja [ 'create-react-app@latest' ] nie udała się, kod błędu: 1
PS C:\Users\Marcin & Joanna\Desktop\mernStack> 

波兰语中的这些行仅表示:
系统找不到指定的路径。
安装['create-react-app @ latest']失败，错误代码1。
我最近将Node升级到了版本14，此后我就遇到了这个问题。
不管安装哪个节点版本，都仍然会出现相同的错误。

您是否在项目目录中尝试过:

npm install

要么

npx autofix

或尝试在其他目录中创建您的应用。
