js文件过大运行报错JavaScript heap out of memory

解决办法：

1、增加内存

在命令前加上：--max_old_space_size=8192，如下

  "scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "unit": "jest --config test/unit/jest.conf.js --coverage",
    "e2e": "node test/e2e/runner.js",
    "test": "npm run unit && npm run e2e",
    "lint": "eslint --ext .js,.vue src test/unit/specs test/e2e/specs",
    "build": "node --max_old_space_size=8192 build/build.js",
    "serve": "node --max_old_space_size=8192 node_modules/.bin/webpack-dev-server serve"
  },

2、使用 increase-memory-limit 插件，增加node服务器内存限制

安装后运行命令仅可，然后安装正常方式运行start命令即可。

npm install -g increase-memory-limit
increase-memory-limit
