Php Composer不下载

我安装了作曲家，所有作品都很好。当我运行

composer-V

时，我只收到一个关于Xdebug的警告

You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug
Composer version 1.0-dev (4c0e163977f8289288df7b37e0fd0469d3e8cbc6) 2016-02-20 19:28:03

我尝试使用

composer require Slim/Slim“^3.0”

安装Slim Framework，但收到以下错误：

Loading composer repositories with package information                                                                               
  [Composer\Downloader\TransportException]

我不确定，但我认为问题在于代理，所以我尝试了提出的解决方案并进行了验证

还是不行。我也在GitHub上找到了，但任何东西都可以

下面是composer diag的结果：

diagnose

还有什么我可以试试的吗

注:

---

我的操作系统是Ubuntu 14.04，我用它来处理Windows代理（TMG）。除了composer，一切都很好（浏览器、apt get、npm等）

此错误是ssl错误，如果您的Web服务器是apache，操作系统是centos 7，则可以通过以下步骤修复此错误： 1.下载并放入~/.cacert

2.将php.ini添加到此

openssl.cafile= ~/.cacert/cacert.pem

3.重新启动apache

systemctl restart httpd.service

希望能帮助你

啊!！一年前我也遇到了同样的问题，一次尝试了很多方法，不确定哪种方法有效，但包括更新一些关于证书的php设置，以及从Mozilla下载cacert.pem。看看这个，它可能会有所帮助，谢谢，但它对我不起作用。。。

systemctl restart httpd.service
