英文:
Unable to run zmq for golang on a mac os X, unknown issue
问题
我正在尝试在我的Go项目中使用gozmq和ZMQ，但是遇到了一些问题，不太确定问题出在哪里。
当我像这样运行我的应用程序时：
$ go run main.go
我得到了以下结果：
# pkg-config --cflags libzmq libzmq libzmq libzmq
exec: "pkg-config": 在 $PATH 中找不到可执行文件
我实际上不知道这是什么意思，为什么会出现这个问题。然而，我猜想可能是我没有安装zmq，或者无法找到它之类的问题...所以我使用brew安装了它：
brew install zmq
但是我得到了以下结果：
Warning: zeromq-4.0.4 already installed
所以我知道我已经安装了它。即使它已经安装了，它仍然无法工作，很奇怪吧？
在gozmq的说明中，确实提到了使用以下命令来安装4.x版本：
go get -tags zmq_4_x github.com/alecthomas/gozmq
我确实运行了：
go get -tags zmq_4_x github.com/alecthomas/gozmq
和
go get -tags zmq_4_0 github.com/alecthomas/gozmq
和
go get -tags zmq_4_0_4 github.com/alecthomas/gozmq
我以为最后一个命令会生效，因为它与我安装的版本匹配，但是以上所有命令都没有生效。
实际上，它们都返回了熟悉的错误信息：
# pkg-config --cflags libzmq libzmq libzmq libzmq
exec: "pkg-config": 在 $PATH 中找不到可执行文件
作为最后的尝试，我尝试访问（官方网站）：
http://zeromq.org/docs:source-git
来安装它，但是他们针对MAC OS X和类Unix系统的说明在我的电脑上不起作用。有人知道发生了什么吗？我还应该尝试什么？
英文:
I was trying to use gozmq for my go project with ZMQ however, I was having some problems and wasn't really sure what the problem was.
When I run my application with zmq as in:
$ go run main.go
I get back:
# pkg-config --cflags libzmq libzmq libzmq libzmq
exec: "pkg-config": executable file not found in $PATH
I don't actually know what it means or why it comes up. However, I guessed that I didn't install zmq or it cannot find it or something...so I brew installed it with
brew install zmq
But I get:
Warning: zeromq-4.0.4 already installed
So I know that I already installed it. Even though its installed it doesn't work, weird?
The instruction at gozmq do say to run for 4.x install with:
go get -tags zmq_4_x github.com/alecthomas/gozmq
I literally ran:
go get -tags zmq_4_x github.com/alecthomas/gozmq
and
go get -tags zmq_4_0 github.com/alecthomas/gozmq
and
go get -tags zmq_4_0_4 github.com/alecthomas/gozmq
I thought the last one would work since it matches the version I had but non of the above worked.
In fact they all just returned the familiar error:
# pkg-config --cflags libzmq libzmq libzmq libzmq
exec: "pkg-config": executable file not found in $PATH
As a last resource I tried to go to (the official site) at:
http://zeromq.org/docs:source-git
to install it but the instruction they have for MAC OS X and Unix-like systems does not work for my computer. Does anyone know whats going on? What else should I try?

pkg-config的问题很容易解决。我只需按照建议中的重复安装它。
然而，如果你仔细看一下，我安装的是4.0.4版本的zmq，这似乎是gozmq不完全支持的版本（或者它不工作，因为编译器抛出错误）。
然后我不得不去安装zmq的3.2.4版本，并安装适用于该版本的gozmq。
要做到这一点，请参考https://stackoverflow.com/questions/3987683/homebrew-install-specific-version-of-formula，该链接展示了如何在brew中安装特定版本的任何软件。
英文:
The problem for pkg-config was easy to solve. I just brew installed it as the duplicate suggested.
However,if you look a little closer, I had 4.0.4. Which seems to be a version of zmq that is not properly supported by gozmq (or it doesn't work because it has errors thrown by the compiler).
I had to then go and brew install zmq but version 3.2.4 and then install the gozmq version for that zmq version.
To do that read https://stackoverflow.com/questions/3987683/homebrew-install-specific-version-of-formula that shows you how to install a specific version of anything in brew.
