当我重新启动计算机时，这才刚刚开始发生...为什么

我找不到我正在调用require（）的地方...也许我安装了一个插件？

Answer 1

删除nodes_modules
npm install -g npm
npm install & npm install -D
npm run start

Answer 2

就我而言，已经在项目级别创建了setupProxy.js文件，后来我删除了其中的配置，但没有删除该文件。因此，引发了上述错误。要解决此问题，请根据需要尝试以下方法之一，

更新setupProxy.js中的正确配置
如果不需要，请删除setupProxy.js
不要将setupProxy.js保留为空文件

Answer 3

感谢@Srinivas 在问题评论中的回复。

删除生成的 setupProxy.js 文件。如果您想使用代理，请将其添加到您的 package.json 文件中。

  "proxy": "http://localhost:3000",

对于像这样的 setupProxy.js 文件：

const proxy = require('http-proxy-middleware');

// tells the browser to direct any relative reference paths to the below 
// domain instead of our own
module.exports = function(app) {
  app.use(proxy('/api/*', { target: 'http://localhost:3000' }));*/
};

npm开始抛出错误状态1要求不是函数
