Problems installing gozmq with go get
问题
我正在尝试使用常规的go get命令安装gozmq：
go get github.com/alecthomas/gozmq
然而，我遇到了以下错误：
# pkg-config --cflags libzmq libzmq libzmq libzmqexec: "pkg-config": 在$PATH中找不到可执行文件
我不太理解这个错误的含义。这是不是意味着它正在尝试运行命令# pkg-config --cflags libzmq libzmq libzmq libzmq，但由于$PATH中没有pkg-config，所以失败了？pkg-config到底是什么，为什么我需要它？我该如何安装它？
我尝试使用brew安装pkg-config，但它没有起作用，并且抛出了以下错误：
# pkg-config --cflags libzmq libzmq libzmq libzmq在pkg-config搜索路径中找不到包libzmq。也许你应该将包含`libzmq.pc`的目录添加到PKG_CONFIG_PATH环境变量中。找不到包'libzmq'在pkg-config搜索路径中找不到包libzmq。也许你应该将包含`libzmq.pc`的目录添加到PKG_CONFIG_PATH环境变量中。找不到包'libzmq'在pkg-config搜索路径中找不到包libzmq。也许你应该将包含`libzmq.pc`的目录添加到PKG_CONFIG_PATH环境变量中。找不到包'libzmq'在pkg-config搜索路径中找不到包libzmq。也许你应该将包含`libzmq.pc`的目录添加到PKG_CONFIG_PATH环境变量中。找不到包'libzmq'退出状态1
不确定为什么会发生这种情况。
编辑：
正如第一个回答者建议的那样，我执行了以下操作：
brew install --devel zeromq
然而，在我执行go get github.com/alecthomas/gozmq之后，我遇到了以下错误：
错误：
# github.com/alecthomas/gozmq37: error: use of undeclared identifier 'ZMQ_SWAP'37: error: use of undeclared identifier 'ZMQ_RECOVERY_IVL_MSEC'37: error: use of undeclared identifier 'ZMQ_MCAST_LOOP'38: error: use of undeclared identifier 'ZMQ_HWM'
这些似乎是"go"的正常错误/警告。但它们来自我从网上获取的一个库。我不确定该怎么办，是否应该自己修复它们，或者应该采取什么措施来解决问题，或者向原始开发者/社区发送电子邮件或提交问题到git等。
英文:
I was trying to install gozmq with the usual go get:
go get github.com/alecthomas/gozmq
However, I was having the following error:
# pkg-config --cflags libzmq libzmq libzmq libzmqexec: "pkg-config": executable file not found in $PATH
I don't really understand what this error means. Does it mean that its trying to run the command # pkg-config --cflags libzmq libzmq libzmq libzmqand its failing because pkg-config is not on $PATH? What is pkg-config anyway and why do I need it? how do I install it?
I tried brew installing pkg-config but it didn't work and it threw me the following error:
# pkg-config --cflags libzmq libzmq libzmq libzmqPackage libzmq was not found in the pkg-config search path.Perhaps you should add the directory containing `libzmq.pc'to the PKG_CONFIG_PATH environment variableNo package 'libzmq' foundPackage libzmq was not found in the pkg-config search path.Perhaps you should add the directory containing `libzmq.pc'to the PKG_CONFIG_PATH environment variableNo package 'libzmq' foundPackage libzmq was not found in the pkg-config search path.Perhaps you should add the directory containing `libzmq.pc'to the PKG_CONFIG_PATH environment variableNo package 'libzmq' foundPackage libzmq was not found in the pkg-config search path.Perhaps you should add the directory containing `libzmq.pc'to the PKG_CONFIG_PATH environment variableNo package 'libzmq' foundexit status 1
not sure why that happened.
EDIT:
As the first answerer suggested, I did:
brew install --devel zeromq
however, I get the following error after I do go get github.com/alecthomas/gozmq
Error:
# github.com/alecthomas/gozmq37: error: use of undeclared identifier 'ZMQ_SWAP'37: error: use of undeclared identifier 'ZMQ_RECOVERY_IVL_MSEC'37: error: use of undeclared identifier 'ZMQ_MCAST_LOOP'38: error: use of undeclared identifier 'ZMQ_HWM'
seem to be "normal" go errors/warning. But they come from a library I got online. I am not sure what to do, if I should fix them myself or what I should to to address it or e-mail the original developers/community or git issue etc.

你需要安装这些库的开发版本。
$ brew install --devel zeromq
根据问题98的说明，如果你使用的是zeromq v3.x，你需要使用：
go get -tags zmq_3_x github.com/alecthomas/gozmq# 或者如果你使用的是4xgo get -tags zmq_4_x github.com/alecthomas/gozmq
请查看README。
英文:
You need to install the development versions of those libraries.
$ brew install --devel zeromq
According to issue 98, if you're using zeromq v3.x you need to use :
go get -tags zmq_3_x github.com/alecthomas/gozmq# or if you're using 4xgo get -tags zmq_4_x github.com/alecthomas/gozmq
Check the README.
