我已经尝试使用命令npx create-react-app有一段时间了，但我一直以这种方式遇到错误。
我正在开发一个windows 10，npm版本-7.6.3和节点-12.18.2
npm WARN registry Unexpected warning for http://registry.npmjs.org/: Miscellaneous Warning ERR_SOCKET_TIMEOUT: request to http://registry.npmjs.org/universalify failed, reason: Socket timeout

我尝试过的：
我也尝试了这个流行的解决方案，我在网上找到了npm cache clean --force，我得到了这个作为输出：
npm WARN using --force Recommended protections disabled.
我不确定是否与它显示的输出一起工作。
我去了C:\Users\Habib\AppData\Roaming\npm目录，手动删除node_modules文件夹和一些与创建反应应用程序相关的文件，然后我尝试了npm cache clean --force，它成功地给出了消息npm WARN using --force I sure hope you know what you are doing.
然后我运行命令npm install -g create-react-app，我认为它成功地给出了响应：
C:UsersHabibAppDataRoamingnpmcreate-react-app -> C:UsersHabibAppDataRoamingnpmnode_modulescreate-react-appindex.js
+ create-react-app@4.0.3
added 67 packages from 25 contributors in 51.721s
然后我尝试了npx create-react-app tutorial1，但它给出了以下错误：
