这个是报的错
[Composer\Downloader\TransportException]  The "http://packages.zendframework.com/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:  error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed  Failed to enable crypto

将证书安装到~$ mkdir ~/tools/https-ca ~$ cd ~/tools/https-ca ~$ curl http://curl.haxx.se/ca/cacert.pem -o cacert.pem地址在/Users/jackluo/tools/https-ca/cacert.pem然后修改php.ini文件openssl.cafile=/Users/jackluo/tools/https-ca/cacert.pem这样至少不报错了gitconfig 证书:export GIT_CURL_VERBOSE=1 ~$ git config --global http.sslCAInfo /Users/jackluo/tools/https-ca/cacert.pem可打开~/.gitconfig确认cainfo配置成功写入git配置文件
