安装Composer OpenSSL问题

嗨伙计们我想安装composer但是当我去安装它时我得到这个错误:

Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The openssl extension is missing, which means that secure HTTPS transfers are impossible.
If possible you should enable it or recompile php with --with-openssl

我目前有php 5.4.31,我正在运行WAMP2.2我已经检查了我的php.ini文件,bin/php/php5.4.31/并确保取消注释以下行:

extension=php_openssl.dll

错误仍然解决,我不知道如何解决它.正如我想的那样,通过取消注释它将被启用.

此外,当我在终端窗口中运行此命令时,php --ini我收到以下消息:

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\php_openssl.dll' - The specified module could not be found
