为什么我在尝试安装我的 React 应用程序时不断收到错误消息

Question

这是我第一次尝试 React，一次又一次地看到同样的错误让我非常沮丧。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

所有这些给了我：

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\_logs20-04-18T14_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.

求助！！！
