遵循以下步骤:

Open your XAMPP control panel then click its "Config" Choose the "Apache (httpd.conf)" and find this code below and change it into this one: #Change this to Listen on specific IP addresses as shown below #to prevent Apache from glomming onto all bound IP addresses. #Listen 0.0.0.0:80 #Listen [::]:80 Listen 80 # Dynamic Shared Object (DSO) Support Save it (Ctrl + S) After that, go back to the XAMPP control panel and click its config again. Choose "Apache (httpd-ssl.conf)", find this code below, and change it again: # Note: Configurations that use IPv6 but not IPv4-mapped addresses need two # Listen directives: "Listen [::]:443" and "Listen 0.0.0.0:443" # #Listen 0.0.0.0:443 #Listen [::]:443 Listen 443 Save it (Ctrl + S) Then, click the "config" (note: above the netstat) and click the "service and port settings". Change "Main Port" to 8080 and "SSL Port" to 4433, then save it. Finally, go to the "control panel" -> "Programs & Features" -> "Turn Windows On or Off". Uncheck your "Internet Information Services", and then click OK.

只需等待它，您的计算机/笔记本电脑将自动重新启动，并尝试再次打开XAMPP控制面板，然后启动Apache。

我通过停止“Web部署代理服务”解决了这个问题。打开:System -> Computer Management -> Services -> Web部署代理服务。停止此服务并启动XAMPP工作。 我想这是MS Webmatrix提供的一项服务。

我试图在cmd中执行httpd.exe，得到错误，在httpd-vhosts.conf中有语法错误。 我检查了文件，发现了什么问题，现在工作正常。

所以，如果你面临这个错误，那么它可能是因为httpd-vhosts或任何其他文件。

尝试通过cmd执行程序，您将得到错误细节和语法错误所在行。

祝你好运

如果上面所有的答案都不奏效，那么就这么做。注释掉php.ini文件中的所有扩展名。

In xampp control panel, click on Apache config. click on php.ini In php ctrl + F (extension) to find all extensions in your php.ini Comment out each and every active extension by adding a ; at the start of each extension line. example ;;;extension=bz2 i put 3 ;;; because i wanted to know ones i commented out so that when i come back to deburg which one had a problem, it was easy for me to see which ones i commented out. Make sure all extensions=whatever are commented out. Run your apache server. To pickup which extension was the problem, one by one un-comment your extensions while restarting your server until you catch the culprit.

即使我也有这个问题，我解决了，在我的情况下，它是不同的。

首先，我尝试卸载skype，但没有工作。但是在我的windows 10桌面中，我默认安装了IIS(Internet Information Server)，指向80端口。

我所做的就是将端口号更改为8081，并重新启动XAMPP，这对我来说很有效。

但是我没有使用IIS。

如果你正在使用Skype，你会得到这个错误。

只需按Ctrl+Alt+Del goto任务管理器选择Skype，然后单击结束任务，然后返回并启动Apache，一旦Apache启动成功。然后再打开Skype现在都将工作良好。

无需更改任何端口。
