作曲家不下载

Question

我安装了作曲家，一切都很好。当我运行composer -V时，我只收到一个关于X调试的警告。

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

我尝试用composer require slim/slim "^3.0"安装Slim，并收到以下错误：

Loading composer repositories with package information                                                                               
  [Composer\Downloader\TransportException]                                     
  The "https://packagist.org/packages.json" file could not be downloaded: SSL  
  : Connection reset by peer                                                   
  Failed to enable crypto                                                      
  failed to open stream: operation failed

我不确定，但我认为问题是代理，所以我尝试了提出的解决方案这里和这里。

export HTTP_PROXY="http://127.0.0.1:3128"
export HTTP_PROXY_REQUEST_FULLURI=0 
export HTTPS_PROXY_REQUEST_FULLURI=0

还是不起作用。我也在GitHub上找到了GitHub，但是任何东西都能工作。

以下是composer diag的结果

还有什么我可以试试的吗？

备注：

我的操作系统是Ubuntu14.04，我使用CNTLM来处理Windows (TMG)。除了作曲家，一切都很好(浏览器，apt-get，npm……)；

这个错误是SSL错误，如果您的you服务器是Apache，并且os是centos 7，那么您可以在接下来的步骤中修复它：

1. 下载http://curl.haxx.se/ca/cacert.pem并将其放入~/..cacert
2. 添加php.ini openssl.cafile= ~/..cacert/acert.pem
3. 重新启动Apache 重新启动httpd.service
