ruby-on-rails - 在 Mountain Lion 上安装 zmq gem

Question

通过 Homebrew 软件安装了 zmq。

然后尝试运行:

$ sudo gem install zmq -- --with-zmq-dir=/usr/local
Building native extensions.  This could take a while...
ERROR:  Error installing zmq:
    ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb --with-zmq-dir=/usr/local
checking for zmq.h... yes
checking for zmq_init() in -lzmq... no

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/zmq-2.1.4 for inspection.

有什么想法吗？

Answer 1

问题是 the current gem does not work with 3.x.x .
但是，您可以使用 brew install zeromq22 安装 ZeroMQ 2.2.0，之后 gem 将安装得很好。
