vue项目热更新内存溢出问题

vue项目启动后，每次修改部分代码，再编译和打包时会频繁内存溢出，都会导致项目运行中断。有的同事是时不时会中断，我是每次都会中断

报错信息如下：

> node –max_old_space_size=4096 webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

module.js:549
    throw err;
    ^

但对于我的电脑不适用，除了安装fix-memory-limit插件之外，还另外做了以下配置

// 找到以下路径
./node_modules/.bin/webpack-dev-server.cmd

// 在node后面增加    --max-old-space-size=4096
@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe"  "%~dp0\..\webpack-dev-server\bin\webpack-dev-server.js" %*
) ELSE (
  @SETLOCAL
  @SET PATHEXT=%PATHEXT:;.JS;=;%
  node  --max-old-space-size=4096 "%~dp0\..\webpack-dev-server\bin\webpack-dev-server.js" %*
)

至此解决项目热更新时，每次保存会报错的问题。

哦豁.jpg

但直到上周调试项目，删除了node_modules，并重新安装依赖后又开始出现热加载内存溢出的问题，但是之前安装的插件和修改的配置依旧在（无语）。

各种百度后，大多建议安装fix-memory-limit，或者在package.json文件的script调试中，增加--max-old-space-size=4096。
因为fix-memory-limit已经存在，尝试直接执行npm run fix-memory-limit命令，再启动项目发现又可以了。
