PHP 7.3 找不到 curl

Question

我在 ma​​cOS Big Sur (11.2.1) 上使用 PHP 7.3。
输入 php -version 时，我收到以下错误消息：

    php --version                                                                                                                                                        11:12:02

我的电脑出了点问题。
当我键入 php --ini 时，我收到以下消息：

php --ini                                                                                                                                                            11:33:04

那里已经缺少 curl 扩展。
当我查看 php.ini 时，扩展名被激活。
除非需要额外的步骤？
vi /usr/local/etc/php/7.3/php.ini

这是输出：
