If you expected pyzmq to link against an installed libzmq, please check to make sure:

    * You have a C compiler installed
    * A development version of Python is installed (including headers)
    * A development version of ZMQ >= 2.1.4 is installed (including headers)
    * If ZMQ is not in a default location, supply the argument --zmq=<path>
    * If you did recently install ZMQ to a default location,
      try rebuilding the ld cache with `sudo ldconfig`
      or specify zmq's location with `--zmq=/usr/local`

You can skip all this detection/waiting nonsense if you know
you want pyzmq to bundle libzmq as an extension by passing:

    `--zmq=bundled`

I will now try to build libzmq as a Python extension
unless you interrupt me (^C) in the next 10 seconds...

I just went through the same process. As the PyZMQ Readme.md says:

我只是经历了同样的过程。PyZMQ Readme。医学博士说:

When compiling pyzmq (e.g. installing with pip on Linux), it is generally recommended that zeromq be installed separately, via homebrew, apt, yum, etc. If this is not available, pyzmq will try to build libzmq as a Python Extension, though this is not guaranteed to work.

在编译pyzmq(例如在Linux上安装pip)时，通常建议将zeromq单独安装，通过homebrew、apt、yum等。如果这是不可用的，pyzmq将尝试将libzmq构建为Python扩展，尽管这不能保证工作。

So as in my case, in your case it didn't work. You can either use Cygwin to install zeromq or download it yourself: http://zeromq.org/intro:get-the-software (I went for the latest, Stable Release 4.0.4)

在我的例子中，在你的例子中它不起作用。你可以使用Cygwin来安装zeromq或者自己下载:http://zeromq.org/intro:get-the-software(我去了最新的，稳定版4.0.4)

unztar, configure (--prefix=/my/home/local if you wish), make install

unztar, configure(-前缀=/my/home/local if you wish)，进行安装。

Then you need to export PKG_CONFIG_PATH=/my/home/local/lib/pkgconfig (or whatever your default lib directory is, e.g. /usr/local/lib/pkgconfig).

然后需要导出PKG_CONFIG_PATH=/ home/local/lib/pkgconfig(或者任何默认的lib目录，例如/usr/local/lib/pkgconfig)。

Make sure this path exists:

确保这条路径存在:

/my/home/local/lib/pkgconfig/libzmq.pc

Finally pip install pyzmq and it should pick up the libzmq.pc file you've just built.

最后，pip安装pyzmq，它应该接收libzmq。你刚刚建立的pc文件。

Install a pre-compiled windows binary if you are using windows.

如果您正在使用windows，请安装预编译的windows二进制文件。

For example from Gohlke's great directory of windows binaries: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyzmq

例如，从Gohlke的大目录的windows二进制文件:http://www.lfd.uci.edu/~ Gohlke /pythonlibs/#pyzmq。
