我在我的macbook pro上安装了php 7.3.4，并且我正在尝试启用一个作者需要（intl）的php扩展。我已经在php.ini中启用了扩展intl，我收到了一条错误消息，说它无法找到 - 所以我假设这意味着我需要安装它。我在网上找到了关于如何安装扩展的教程（链接在底部），我遵循了这一点。在我运行sudo pecl install intl的阶段，我收到一个错误; make：*** [php_intl.lo]错误1错误：`make'失败
有没有人有办法解决吗？

我按照在线教程进入这个阶段，这是http://budiirawan.com/install-php-intl-extension-os-x/
我已经通过使用macports而不是pecl安装扩展来解决这个问题。
