问题描述
我在使用 Xdebug 运行测试时遇到问题。 Xdebug 没有停止到断点，它说在我尝试 PHPStorm 后，在左下角“未建立连接无法使用 'Xdebug 2.8.1' 启动调试器会话
关于我的环境的一些信息：
- PHP 7.4.20（我从自制软件安装了这个版本）
- Xdebug 2.8.1
在我的 PHPinfo 中：
Runtime: PHP 7.4.20 with Xdebug 2.8.1

如果我在这里运行 /usr/local/Cellar/PHP@7.4/7.4.20/bin PHPize 说（我不知道它是否已连接）：
Cannot find config.m4.
Make sure that you run '/usr/local/opt/PHP@7.4/bin/PHPize' in the top level source directory of the module
在我的 PHP.ini 中，我没有添加任何关于 Xdebug 配置的内容，但是我可以找到 xdebug.ini：
zend_extension=xdebug.so
我错过了什么？
解决方法
根据您的 Xdebug 日志，您需要将 Xdebug 端口从默认的 9000 更改为其他数字（例如 9003 - 在 Xdebug 3 中默认使用）。在 PHP（我猜是 xdebug.ini）和 PhpStorm 中执行此操作。
在您的计算机上，php-fpm 似乎已经在使用 TCP 9000 端口（它也默认使用该端口 + 在这种情况下您可以看到的典型响应）或其他一些服务知道 Xdebug 协议。
Homebrew 的意思是 Mac，对吧？ PhpStorm 在 Mac 上检测已在使用的端口时存在问题（因此 IDE 不会发出警告：在 Windows 和 Linux 上，您会在这种情况下看到警告）。您可以使用 netstat 或类似程序（例如 Mac 上的 sudo lsof -nP -iTCP -sTCP:LISTEN）检查哪个进程使用该端口。
