所以几个月来我一直在开发一个完整的 React 应用程序。出于某种原因，当我尝试npm run start在命令行上运行时，似乎不知从何而来，它产生了以下错误；

// npm run start

> pair@0.1.0 start /Users/eden/Documents/GitHub/Pair./pair
> react-scripts start

/Users/eden/Documents/GitHub/Pair./pair/node_modules/react-dev-utils/WebpackDevServerUtils.js:166

我尝试了以下方法；

  • 卸载/重新安装节点
  • 卸载/重新安装 npm
  • 确保 node 和 npm 是版本 6 或更高版本
  • 删除node_modules并package-lock.json重新运行npm-i
  • 卸载/重新安装反应脚本
  • 降级反应脚本
  • 跑步npm install --save react react-dom react-scripts
  • 卸载/重新安装 react-dev-utils

WebpackDevServerUtils.js我什至尝试将 react-dev-utils的GitHub 主页中的内容复制/粘贴到我的本地node_modules/react-dev-utils/WebpackDevServerUtils.js以解决语法错误。

我不知道为什么会这样。下面是这次运行的日志；

我查看了 WebpackDevServerUtils.js 的第 166 行，并使用 ESLint 来识别语法错误，但找不到任何东西。

因此，我的问题是：如何解决这个晦涩的错误？

错误似乎在异步上，您使用的是不支持异步/等待的节点 6。更新到支持它的最新版本的节点（7.6），你应该很好。
