node.js - 安装reactjs时出错: Error unexpected end of JSON input while parsing near

Question

我尝试在终端中使用两个不同的命令通过 Node 安装reactjs，使用1) npx create-react-app my-app和 2) npx create-react-app app

但是两者都产生了相同的错误，如下所示:

Installing packages. This might take a couple of minutes.

Installing react, react-dom, and react-scripts with cra-template...

npm ERR! Unexpected end of JSON input while parsing near '....1","object-hash":"^1'

npm ERR! A complete log of this run can be found in:

npm ERR! C:\Users\David\AppData\Roaming\npm-cache_logs\2020-02-12T03_53_37_836Z-debug.log

Aborting installation.

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

我尝试卸载并重新安装 Node ，还尝试安装不同旧版本的reactjs，但仍然遇到相同的错误。另外，我尝试清除 Node 缓存，然后通过npm cache clear --force再次验证它。然后npm cache verify但仍然没有任何运气。任何帮助将不胜感激。

更详细的日志显示在底部:
