    An error occurred while installing dnssd (2.0), and Bundler cannot continue.
    Make sure that `gem install dnssd -v '2.0'` succeeds before bundling.

我已安装gem install dnssd -v'2.0'，但问题仍然存在。帮我解决一下。

Answer 1

dnssd gem依赖于具有dnssd库的操作系统。假设你没有使用我认为内置了这个库的OS X，你应该安装libavahi-compat-libdnssd-dev。

在Ubuntu上，它是sudo apt-get install libavahi-compat-libdnssd-dev

Answer 2

我猜你不在OSX上。如果您使用的是Ubuntu，则可以运行

$> sudo apt-get install libavahi-compat-libdnssd-dev

安装缺少的库。

使用ruby 1.9.2安装gem'frank-cucumber'时出错
