看了很多解决办法：

解决方案1：通过 increase-memory-limit 插件
安装插件：npm install -g increase-memory-limit
执行命令：npx cross-env LIMIT=4096 increase-memory-limit

解决方案2：设置max-old-space-size即可。在工程目录node_modules.bin下找到umi.cmd文件，替换下面代码，重新启动即可。

@IF EXIST "%~dp0\node.exe" ("%~dp0\node.exe" --max_old_space_size=8192 "%~dp0\..\umi\bin\umi.js" %*
) ELSE (@SETLOCAL@SET PATHEXT=%PATHEXT:;.JS;=;%node  --max_old_space_size=8192 "%~dp0\..\umi\bin\umi.js" %*
)
