**解决方案**：  
在node\_modules下找到.bin文件夹下的webpack-dev-server.cmd文件，并在node命令后添加参数代码：

--max_old_space_size=4096

@IF EXIST "%~dp0\node.exe" (
      "%~dp0\node.exe"   --max_old_space_size=4096 "%~dp0\..\webpack-dev-server\bin\webpack-dev-server.js" %*
    ) ELSE (
      @SETLOCAL
      @SET PATHEXT=%PATHEXT:;.JS;=;%
      node   --max_old_space_size=4096  "%~dp0\..\webpack-dev-server\bin\webpack-dev-server.js" %*
    )
