An error occurred while installing hiredis (0.5.2), and Bundler cannot continue.
Make sure that `gem install hiredis -v '0.5.2'` succeeds before bundling.

人们说Windows不受支持，但extconf.rb有mswin option ...

关于我应该做什么的任何想法？

坏消息：

hiredis目前无法在Windows上运行，Windows特定代码只是样板代码。虽然已经完成了一些工作并且有一些拉取请求（#52似乎是最相关的）但看起来这是一项艰巨的任务。

不幸的是，即使拉动请求也需要使用Visual Studio（而不是MinGW）进行编译，因此将来必须捆绑二进制文件并随hiredis Ruby gem一起提供。在使hiredis与Windows兼容之前，维护者还需要维护人员的长期承诺。

总而言之，它看起来不像hiredis可以很快安装在Windows上。

好消息：

hiredis gem是Ruby version of the Redis client的高效替代。如果无法加载，则会自动使用较慢的实现。您所要做的就是强制安装hiredis gem以实现gem依赖性。

在gem install hiredis调用失败后，您可以按照in the gem install documentation所述手动编写gem规范：

例如，在lib\ruby\gems\2.2.0中，您可以运行：

gem spec cache\hiredis-0.5.2.gem --ruby > specifications\hiredis-0.5.2.gemspec

启动Rails 5应用程序时会收到警告，但除此之外应该有效。

Windows上的Hiredis 0.5.2
