installing CakePhp: "Your requirements could not be resolved to an installable set of packages" error
我正在尝试通过此 tutorial 使用 composer 安装 cakephp 但是在我 运行 命令之后：
sudo composer create-project --prefer-dist cakephp/app my_app_name
我收到错误：

我使用 curl 和 composer 安装了 codeSniffer。我仍然无法摆脱错误。知道我做错了什么吗？
codeSniffer 似乎需要 squizlabs ^3.0.0。
而且您似乎还需要在 .ini 文件中启用扩展。
您需要安装一些扩展，即：
sudo pear install PHP_CodeSniffer
并且还为作曲家启用 php 扩展，即 curl,intl
sudo apt-get update
sudo apt-get install curl php-cli php-mbstring git unzip
额外选项：
全局安装 composer :
sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
我曾经有过类似的错误。它已通过安装 php-xml 修复。确保你也安装了 waris 所说的。
sudo apt-get install php-xml

第一个 php 版本
php -v
和
sudo apt-get install <your php version>-xml
