windows下安装PrestaShop报错

Unable to generate private keys using openssl_pkey_new. Check your OpenSSL configuration, especially the path to openssl.cafile.

这里只说解决办法，不讨论程序运行

不论是xampp, wamp, wnmp, PHPstudy，还是宝塔，都可能产生这个问题

In Windows you need to go in "Environment Variables" in "System Variables" Add Variable name: "OPENSSL_CONF" Variable Value: "X:\XXX\XXX\XXX\openssl.cnf" path where you installed xampp, wamp, wnmp . Restart PC It will work. 

打开系统属性，找到环境变量

在系统变量中添加OPENSSL_CONF，变量值为你安装环境下对应配置文件位置，比如我的D:\BtSoft\php\74\extras\ssl\openssl.cnf，找不到可以搜索openssl.cnf

确定后重启服务器，提示错误会消失
