在带有 Wampserver 2.5 的 Windows 7 64 位上安装 Composer 时出错

Question

我正在尝试在 W7 64x 上安装 Composer。使用 Composer 网站提供的 Windows 安装程序 (Composer-setup.exe)。

我已经安装了带有 php5.5.12 和 Apache2.4.9 的 Wampserver 2.5。 openssl 在 php.ini 中启用。

我在安装过程中遇到以下错误：

Download failed: file_get_contents(): SSL operation failed with code 1. OpenSSL Error
messages:

file_get_contents(): Failed to enable crypto

The download failed repeatedly, aborting.

我安装了xampp和WPN XM，但是使用两者的php.exe都显示如下错误：

Connection Error [ERR_CONNECTION]: Unable to connect to getcomposer.org
Request to https://getcomposer.org/installer failed with errors:
SSL operation failed with code 1. OpenSSL Error messages:

failed. Failed to enable crypto. Failed to open stream: operation failed

确保 SSL 证书已安装并由 PHP 找到。

在php.ini:

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

如果缺少证书：从http://curl.haxx.se/ca/cacert.pem 下载证书包并保存为ca-bundle.crt。

（或者简单地使用 Windows 的服务器堆栈，它提供了开箱即用的 Composer：WPN-XM）
