Phpstudy的apache启动失败

1，dos下执行检查命令:如f:\phpStudy\PHPTutorial\Apache\bin\httpd.exe
2,显示报错信息:
C:\Users\Administrator>f:\phpStudy\PHPTutorial\Apache\bin\httpd.exe
AH00526: Syntax error on line 223 of F:/phpStudy/PHPTutorial/Apache/conf/httpd.c
onf:
DocumentRoot must be a directory
3,处理报错的问题
4,txt文件下显示选择查看状态栏，光标点在哪下方就会显示当前行数，用来解决http.conf具体哪一行报错
