Nuxt js开发环境中CPU使用率高

Posted 2023-03-08

【中文标题】Nuxt js开发环境中CPU使用率高

【英文标题】：Nuxt js high CPU usage in dev environment

【发布时间】：2020-09-06 16:13:14

【问题描述】：

由于更新很少，我在 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

我在不同论坛尝试了很多类似问题的东西，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节点模块

我不知道我应该检查什么来解决这个问题

MacOS Catalina 10.15.4

Node v13.12.0

【问题讨论】：

在 Mac 的 Docker Desktop 上有带有主机目录绑定挂载的 known performance issues。对于基于浏览器的应用程序，安装原生 Node 可能比尝试使用 Docker 模拟原生开发环境效果更好。

【参考方案1】：

可能是 webpack 的 watch 模式有问题。 如here所述：

对于某些系统，查看多个文件系统可能会导致大量 CPU 或内存使用。可以排除像 node_modules 这样的巨大文件夹

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

在你的情况下（nuxt.js），只需添加到 nuxt.config.js

 watchers: 
    webpack: 
      ignored: /node_modules/
