vue+webstrom JavaScript heap out

开发过程中的问题描述：

本地开发环境，添加新页面 或者 修改代码后，webstrom就自动终止npm run了，提示‘JavaScript heap out of memory’，如下：

95% emittingFATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

重点及解决方案

• 本地开发环境
• 使用的版本 vue@2.5.2
• package.json 中 dev的原始配置如下

"scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js --host 192.168.1.93",
    "start": "npm run dev",
    "build": "node build/build.js",
    "pro": "node --max_old_space_size=9000 build/build.js "
  },

• 最终解决方案为 修改package.json：注意，修改的是dev ↓↓

"scripts": {
    "dev": "node --max-old-space-size=4096 ./node_modules/.bin/webpack-dev-server --inline --progress --config build/webpack.dev.conf.js --host 192.168.1.93",
    "start": "npm run dev",
    "build": "node build/build.js",
    "pro": "node --max_old_space_size=9000 build/build.js "
  },
