reactjs - 我无法使用 npx create-react-app 安装 React？

Question

我正在尝试使用 npx create-react 应用程序，但出现如下错误:

npm ERR! Unexpected end of Json input while parsing near
'...eact-app/-/create-rea'

npm ERR! A complete log of this run can be found in: npm ERR!
C:\Users\dp\AppData\Roaming\npm-cache\_logs\2018-12-06T18-42-56-293Z-debug.log

Install for create-react-app@latest failed with code 1** 

错误的日志文件在这里......!

我怎样才能摆脱这个麻烦？
