我刚刚创建了一个 react js 项目.然后我运行npm start"来运行项目.这个错误来了，我现在被困在这里 1 天了.我已经有其他的 reactJS 项目了.此错误适用于所有其他项目.这就是为什么我在新项目中尝试了它.所以我通过创建新项目来确认.错误不在我的项目中.

I just created a react js project. Then I run "npm start" for run the project. this error come and I am stuck here for 1 day now. I have already have other reactJS projects. This error came for all other projects. That's why I tried it with new project. So I confirmed by creating new project. Error is not in my project.

我已经试过了.

• 减少'react-script'的版本
• 卸载node.js，删除c盘所有名称为node"的文件
• 安装旧版本的 node.js
