我正在尝试使用MAMP在本地设置一个新的CakePHP3项目。
当我使用composer安装时，我收到此错误，但应用程序仍会创建：
Your requirements could not be resolved to an installable set of packages.
Problem 1
- cakephp/cakephp 3.2.5 requires ext-intl * -> the requested PHP extension intl is missing from your system.
- cakephp/cakephp 3.2.4 requires ext-intl * -> the requested PHP extension intl is missing from your system.
- cakephp/cakephp 3.2.3 requires ext-intl * -> the requested PHP extension intl is missing from your system.
- cakephp/cakephp 3.2.2 requires ext-intl * -> the requested PHP extension intl is missing from your system.
- cakephp/cakephp 3.2.1 requires ext-intl * -> the requested PHP extension intl is missing from your system.
- cakephp/cakephp 3.2.0 requires ext-intl * -> the requested PHP extension intl is missing from your system.
- Installation request for cakephp/cakephp ~3.2 -> satisfiable by cakephp/cakephp[3.2.0, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.2.5].
这是我的问题吗？
我已按照此处的所有步骤无效：http://book.cakephp.org/3.0/en/installation.html#url-rewriting
我已将文档根目录设置为appname / webroot
我得到的浏览器中的错误是：
The localhost page isn’t working
localhost is currently unable to handle this request.
500
我可以尝试什么？
