因此，对于magento2，我需要安装：PHP Extension intl。
现在，抬起头后，我正在尝试执行此操作，但是我一直在出错。我在MAC上并且正在使用XAMPP，当我运行“ sudo pecl install int”时太可惜了，我得到以下错误。
Starting to download intl-3.0.0.tgz (248,200 bytes)
.....done: 248,200 bytes

我也尝试使用'sudo pecl update-channels'，但这会给我以下消息：
Updating channel "doc.php.net"
Channel "doc.php.net" is not responding over http://, failed with message: File http://doc.php.net:80/channel.xml not valid (redirected but no location)

我该怎么解决？我在PHP 7.2中使用XAMPP
