今天在使用vscode进行前端页面开发时，不能正常进行热更新，每当进行热更新的时候会报内存溢出错误，如下

网上的解释都不太对，
一种说是写的前端代码中有死循环，可能不大
还有一种是因为程序过大导致的，感觉这个原因的概率大一点

解决方法也大概有两中：

// 修改div的分配的内存大小，即修改8192的值，增大
"scripts": {
    "dev": "node --max-old-space-size=8192 build/dev.js"
  },

还有一种就是添加插件

在package.json中进行配置
"dependencies": {
    "increase-memory-limit": "^1.0.3",
    "cross-env": "^5.0.5"
  },

执行npm install 来安装组件 npm install increase-memory-limit

然后再添加如下：

在package.json中进行配置
"scripts": {
    "fix-memory-limit": "cross-env LIMIT=3072 increase-memory-limit"
  },

LIMIT是你想分配的内存大小，然后执行npm run fix-memory-limit
然后在项目执行之前先执行fix-memory-limit，在正常执行dev就OK了
