1、问题描述：
目前在压缩前端代码的时候，出现了node的内存泄漏，错误如下：Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

2、错误如下：

WARNING: The callback-based version of packager() is deprecated and will be removed in a future major version, please convert to the Promise version or use the nodeify module.

3、解决方案
方案一：

在package.json里面：加上这一句：--max_old_space_size=8192// 或  --max_old_space_size=4096（建议先设置成4G看看，如果不行在设置为8G）

"scripts": {
    "dev": "node build/dev-server.js",
    "start": "node build/dev-server.js",
    "build": "node --max_old_space_size=8192 build/build.js"
},

方案二：

删除npmrc文件（不是nodejs安装目录npm模块下的那个npmrc文件，而是C:\Users\{账户}\下的.npmrc文件）
