wamp安装composer不成功

Question

wamp安装composer不成功

1. 我下载了composer的exe文件，但是运行的时候报错了错误如下
   >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
2. 然后我更改了wamp里的apache、php的openssl扩展，安装后又报错了错误如下
   >
   >
3. 之前我的wamp安装好后我改过虚拟域名和www目录配置，改改后还是很好用，改完重启wamp也是可以用的，但是过了几天又没法用了，是不是和这个有关呀。
