Question

我尝试使用命令

在Windows 7上通过composer安装symfony

$ composer create-project symfony/framework-standard-edition www1

我收到错误

[ErrorException]
Use of undefined constant STDIN - assumed 'STDIN'

我需要做些什么来解决这个问题？

另外在应用程序中有3个空文件在“web / bundles”文件夹中，其中必须是包含css文件和图像的文件夹。因此，浏览器中的“web / app_dev.php”页面上没有图像。然后我执行了命令

php app/console assets:install web

并在“web / bundles”中出现图像和css文件，然后图像出现在“web / app_dev.php”页面上，以便正确显示。

Answer 1

可能会出现此错误，因为您的php已安装CGI binary模式，而不是CLI。对此的解决方法可能是放在AppKernel.php文件的顶部以下行：

define('STDIN',fopen("php://stdin","r"));

Answer 2

我发现如果手动STDIN声明解决方案无法实现，以非交互模式（composer -n update）启动编辑器会有所帮助。

您可能需要删除生成提示的供应商文件夹，或者使用--prefer-source，但这是另一个故事。
