二、解决方法

1）升级安装最新npm - 控制台执行“npm install -g increase-memory-limit”命令，操作如下

PS D:\project\protal-ui-1> npm install -g increase-memory-limit@b@C:\Users\Administrator\AppData\Roaming\npm\increase-memory-limit -> C:\Users\Administrator\AppData\Roaming\npm\node_modules\increase-memory-l@b@imit\index.js@b@+ increase-memory-limit@1.0.7@b@added 12 packages from 5 contributors in 4.863s

2）当前项目运行increase-memory-limit 命令，操作如下
