php - 无法使用 PHP 5.6.3 与 Composer 建立 SSL 连接

Question

在使用 PHP 5.6.3 在 Ubuntu 14.04 上克隆存储库后，我无法运行 php composer.phar selfupdate 和 php composer.phar update。我收到此消息:

  [Composer\Downloader\TransportException]                                     
  The "https://getcomposer.org/version" file could not be downloaded: SSL ope  
  ration failed with code 1. OpenSSL Error messages:                           
  error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify   
  failed                                                                       
  Failed to enable crypto                                                      
  failed to open stream: operation failed

我认为问题应该出在我本地拥有的证书上，但我无法想象如何解决它。

这是 composer.json:

{
"name": "zendframework/skeleton-application",
"description": "Skeleton Application for ZF2",
"license": "BSD-3-Clause",
"keywords": [
    "framework",
    "zf2"
],
"homepage": "http://framework.zend.com/",
"require": {
    "php": ">=5.3.3",
    "zendframework/zendframework": "2.3.*",
    "evandotpro/edp-module-layouts": "1.*",
    "tecnick.com/tcpdf": "~6.0@stable",
    "phpoffice/phpexcel": "1.7.*"
},
"require-dev": {
    "phpunit/phpunit": "4.1.*",
    "phpunit/phpunit-selenium": ">=1.2"
},
"autoload": {
    "psr-0": {"BOZA\\": "vendor/BOZA/"},
    "classmap": ["vendor/tecnick.com/tcpdf"]
}

其中一个原因可能是证书丢失或 PHP 找不到。

是否安装了 ca-certificates 包？

如果没有:apt-get install ca-certificates 或者直接从这里下载证书包:

• http://curl.haxx.se/ca/cacert.pem
• https://github.com/bagder/ca-bundle/blob/master/ca-bundle.crt

然后检查并编辑您的 php.ini，以便这些证书用于 PHP 建立的 SSL 连接。

curl.cainfo=/path/to/ssl/certs/ca-bundle.crt
openssl.cafile=/path/to/ssl/certs/ca-bundle.crt
