我有以下设置：
我正在尝试使用pip安装py-bcrypt。最初安装失败，因为找不到vcvars.bat
通过修改指令here，我能够在VS2012编译器上指向python，但是，当我第一次尝试安装时，我得到一系列错误（参见下面的日志）。当我重复安装以将输出通过管道传输到日志文件时，安装报告成功。
但是，看起来安装的版本缺少一些关键功能 - 例如bcrypt.genSalt()方法存在且工作正常但bcrypt.hashpw()未定义。
我会很高兴使用预编译的二进制文件，但是我还没有能够找到任何晚于2.7的python版本
如何让py-bcrypt工作？
（为了简洁，我已经剪断了它跳过的链接）
