创建反应新项目时出错。 使用 create-react-app

Question

我在创建React的新项目时遇到问题。 这是我如何创建反应项目的命令。

npx create-react-app helloworld

但是项目没有成功创建。 下面是错误React 创建新项目的屏幕截图

我在图片中突出显示的区域每次都在变化。 有时使用不同的文件显示此错误。 有时会出现下面提到的响应时间错误：响应时间错误

我尝试了以下解决方案：

• npm config set registry="http://registry.npmjs.org/"
• npm cache clean --force
• 重新安装 node.js

我在这篇文章中附加了几行日志文件。 请帮助我解决这个问题。
