安装gozmq的问题go get

Question

我试图用通常的go get安装gozmq:

go get github.com/alecthomas/gozmq

但是,我遇到以下错误:

# pkg-config --cflags libzmq libzmq libzmq libzmq
exec: "pkg-config": executable file not found in $PATH

我真的不明白这个错误意味着什么.这是否意味着它试图运行命令# pkg-config --cflags libzmq libzmq libzmq libzmq并失败,因为pkg-config它不在$ PATH上？什么是pkg-config反正,为什么我需要它？我该如何安装？

我尝试brew安装pkg-config但它没有工作,它给我扔了以下错误:

# pkg-config --cflags libzmq libzmq libzmq libzmq
Package 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 variable
No package 'libzmq' found
Package libzmq was not found in the pkg-config search path.

exit status 1

不知道为什么会这样.

编辑:

正如第一个回答者建议的那样,我做了:

brew install --devel zeromq

但是,我在执行错误后收到以下go get github.com/alecthomas/gozmq 错误:

# github.com/alecthomas/gozmq
37: 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'

似乎是"正常"去错误/警告.但他们来自我上网的图书馆.我不知道该怎么做,如果我自己应该修复它们或者我应该如何处理它,或者通过电子邮件发送原始开发者/社区或git问题等.

您需要安装这些库的开发版本.

$ brew install --devel zeromq

根据问题98,如果你使用zeromq v3.x你需要使用:

go get -tags zmq_3_x github.com/alecthomas/gozmq
# or if you're using 4x 
go get -tags zmq_4_x github.com/alecthomas/gozmq

检查自述文件.
