我正在尝试安装Laravel Valet,这需要PHP 7.1,但是当我运行brew install PHP71时,我收到以下错误：
==> Pouring PHP71-7.1.10_21.high_sierra.bottle.tar.gz Error: The `brew link` step did not complete successfully The formula built,but is not symlinked into /usr/local Could not symlink sbin/PHP-fpm /usr/local/sbin is not writable.
当我运行brew链接PHP71时,我得到了同样的错误.如果我运行PHP -v,我实际上看到我正在运行PHP 7.1.7.
但是,当我运行valet安装时,我得到：
[DomainException] Unable to determine linked PHP.
我甚至在/usr/local中都没有sbin目录.
有什么建议？
