Symfony 3新项目错误[GuzzleHttp Exception]

I'm on OpenSUSE Leap 42.1 and I installation went without any issues. But when I tried to create new Symfony project running command

symfony new project

I get 2 following exceptions inside the terminal:

[GuzzleHttp\Exception\RequestException]                                          
  No system CA bundle could be found in any of the the common system locations.    
  PHP versions earlier than 5.6 are not properly configured to use the system's    
  CA bundle by default. In order to verify peer certificates, you will need to     
  supply the path on disk to a certificate bundle to the 'verify' request          
  option: http://docs.guzzlephp.org/en/latest/clients.html#verify. If you do not   
  need a specific certificate bundle, then Mozilla provides a commonly used CA     
  bundle which can be downloaded here (provided by the maintainer of cURL):        
  https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt. Once    
  you have a CA bundle available on disk, you can set the 'openssl.cafile' PHP     
  ini setting to point to the path to the file, allowing you to omit the 'verify'  
  request option. See http://curl.haxx.se/docs/sslcerts.html for more              
  information.

I read on symfony github that I need to download this certificate but when I open it, it says that it's already installed.

Edit: Php version is 5.5.14
