我有一个新安装的Symfony，除了我的供应商目录是空的之外，其他所有东西都在看？也就是说，它已经作曲家和学说目录，但它们是空的。如果我站在我的根并运行命令：
$ composer install

在前端浏览到http://symfony.local/web/
Warning: require(C:Apache24htdocssymfony.localapp/../vendor/autoload.php): failed to open stream: No such file or directory in C:Apache24htdocssymfony.localappautoload.php on line 11

很明显，它正在寻找/vendor/autoload.php，但这并不存在。为什么我的供应商目录是空的？我如何确保安装库？
$ composer update返回：

嗯，您的PHP配置不正确。
调整您的/etc/php5/php.ini并启用"ZIP"扩展名。
剩下的可能是权限问题，因为您将Cygwin与Composer结合使用。作曲家和赛文并不是真正的好朋友。
我的建议是：在本机Windows CLI上运行Composer，只针对供应商获取部分。
您想要的是composer update。它将读取您的composer.json以安装所有必需的软件包。composer install用于部署。
下载并启用PHP的zip扩展如果您正在使用PHP7.0并使用debian基本发行版（例如：Ubuntu），请使用以下命令自动安装并启用它
apt-get install php-zip
