修改webpack-dev-server.cmd文件，内容如下：

@ECHO off
SETLOCAL
CALL :find_dp0

IF EXIST "%dp0%\node.exe" (
  SET "_prog=%dp0%\node.exe"
) ELSE (
  SET "_prog=node"
  SET PATHEXT=%PATHEXT:;.JS;=;%
)

"%_prog%" --max-old-space-size=4096 "%dp0%\..\webpack-dev-server\bin\webpack-dev-server.js" %*
ENDLOCAL
EXIT /b %errorlevel%
:find_dp0
SET dp0=%~dp0
EXIT /b

文件存放路径如下

end.
