以前都在linux环境使用php composer。今天尝试在win7下运行composer却出现SSL报错：
E:\data\www\symfony-2.5.6>php -f D:/wamp/php-5.6.2-x64/composer.phar install Loading composer repositories with package information Installing dependencies (including require-dev) SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed”
没有安装CA证书导致的！！！
CA证书下载地址：http://curl.haxx.se/docs/caextract.html
然后修改php.ini文件
openssl.cafile= D:/wamp/php-5.6.2-x64/verify/cacert.pem
就OK了~
