为什么在尝试安装我的React App时总是收到错误消息

Question

这是我第一次尝试React，让我一次又一次看到相同的错误非常令人沮丧。我分别尝试了所有这三个代码
npx create-react-app myapp
npm init react-app myapp
npm install -g create-react-app然后create-react-app myapp

所有给我的东西：

npm ERR! Unexpected end of JSON input while parsing near '...:"^5.0.0 || ^6.0.0"},'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\{hiddenForPrivacyReasons}\AppData\Roaming\npm-cache\_logs\2020-04-18T14_12_44_513Z-debug.log

Aborting installation.
  npm install --save --save-exact --loglevel error react react-dom react-scripts cra-template has failed.

Deleting generated file... package.json
Deleting my-app/ from D:\{hiddenForPrivacyReasons}\codes\app
Done.

帮助！

您不需要react-app和其他脚本

简单地：

npx create-react-app my-app
cd my-app
npm start
