Symfony在我的wamp服务器上安装异常

Question

E:wampwww>composer create-project symfony/framework-standard-edition myproject 

当从CMD

运行上述命令时，我得到了以下错误

[SymfonyComponentDependencyInjectionExceptionInvalidArgumentException]
  $id must be a string, or an Alias object.

Script SensioBundleDistributionBundleComposerScriptHandler::clearCache handl
ing the post-install-cmd event terminated with an exception

  [RuntimeException]

o-scripts] [--no-progress] [--keep-vcs] [--no-install] [--ignore-platform-reqs]

当我尝试在浏览器中打开它时，它显示以下内容

( ! ) Fatal error: Uncaught exception 'SymfonyComponentDependencyInjectionExceptionInvalidArgumentException' with message '$id must be a string, or an Alias object.' in E:wampwwwjiccvendorsymfonysymfonysrcSymfonyComponentDependencyInjectionContainerBuilder.php on line 684

有人能帮我解决这个问题吗?

Answer 1

如果在新安装Symfony时发生这种情况，请考虑运行稳定且长期支持的Symfony版本，目前为2.7:

composer create-project symfony/framework-standard-edition my_project_name "2.7.*"

如果这对你有用，那么请在symfony/symfony-standard中发布一个bug报告。可能在最新版本中引入了错误

Answer 2

我也遇到了同样的问题。尝试在命令中使用-v switch。"php app/console cache:clear -v"查看回溯。

更多关于我的案例:我把所有参数从参数中移走。yml文件到PHP环境变量，然后有这个问题。基本上SwiftMailer停止查看参数值。使用-v开关，我找到了原因。

更新:

我注意到，如果我清除我的缓存手册，例如使用linux的rm -rf app/cache/*命令，我得到了一个错误。但是，如果我使用app/console cache:clear命令清除缓存，一切工作正常。
