解决：1.设置环境变量node运行内存 2.设置hbuildernode运行内存
1.Windows 永久有效(仅用户级别)
cmd中执行setx NODE_OPTIONS --max-old-space-size=8192
或直接在环境变量窗口中编辑用户级别的环境变量。
命令执行后对本cmd窗口之外的所有环境，即刻生效(本cmd窗口开始运行时，还没配置这个环境变量)。
Windows 永久有效(系统级别)
在环境变量窗口中编辑系统级别的环境变量。新增配置：
name: NODE_OPTIONS
value: --max-old-space-size=8192
2. hbuilder -- 工具--设置--运行配置---node启动内存参数：2048
