Apache Internal Server Error

今天我在安装php项目时，老是出现这样的错误：

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, admin@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

我在网上搜了搜，解决的办法是把.htaccess删掉
