node.js - Nuxt js开发环境中CPU使用率高

Question

由于很少更新我的 docker 容器中的应用程序前端部分无法正常工作
它使用了 100% 以上的 Docker CPU，我的笔记本电脑 CPU 的 60/70%(风扇以 100% 运行)
而且 HMR 很慢

此问题不会出现在生产和其他笔记本电脑上

我尝试了来自不同论坛类似问题的很多东西，但没有任何效果

我将 Docker 重置为出厂默认设置，允许更多内存和 CPU
我更新了我的依赖项
我删除并恢复了我的 Node 模块

我不知道我应该检查什么来解决这个问题
MacOS Catalina 10.15.4Node v13.12.0

可能是 webpack 的 watch 模式有问题。
如前所述here :

For some systems, watching many file systems can result in a lot of CPU or memory usage. It is possible to exclude a huge folder like node_modules

module.exports = {
  //...
  watchOptions: {
    ignored: /node_modules/
  }
};

在您的情况下(nuxt.js)，只需添加到 nuxt.config.js

 watchers: {
    webpack: {
      ignored: /node_modules/
    }
  }
