我有以下设置:

  • Win7 x64
  • 蟒蛇 3.3
  • Visual Studio 2012 终极版

我正在尝试使用 pip 安装 py-bcrypt。最初安装失败,因为它找不到vcvars.bat

通过修改此处的说明,我能够将 python 指向 VS2012 编译器,但是,当我第一次尝试安装时,我得到了一系列错误(见下面的日志)。当我重复安装以管道输出到日志文件时,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,该bcrypt.genSalt()方法存在并且工作正常但bcrypt.hashpw()未定义。

我很乐意使用预编译的二进制文件,但是,我找不到任何高于 2.7 的 python 版本

如何让 py-bcrypt 工作?
