need configuration options.

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有一个mswin option...

我该怎么做你有什么建议吗？

坏消息：

hiredis目前不能在Windows上工作，Windows特定的代码只是样板代码。尽管已经完成了一些工作，也有一些pull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，即使是拉取请求也需要使用Visual Studio (而不是MinGW)进行编译，因此在将来，二进制文件必须与hiredis Ruby gem捆绑在一起。此外，维护人员需要维护人员的长期承诺，才能使其与Windows兼容。

总而言之，看起来短期内不太可能在Windows上安装hiredis。

好消息：

hiredis gem是Ruby version of the Redis client的高性能替代。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以满足gem依赖项。

在失败的gem install hiredis调用之后，您可以按照in the gem install documentation的说明手动编写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

当启动一个Rails 5应用程序时，你会得到一个警告，但除此之外，它应该可以工作。
