Question

我正在尝试在cygwin中运行ipython notebook。为此我需要安装pyzmq。然而，这不起作用。我已经附上了问题，有人可以帮忙吗？

Did not find libzmq via pkg-config:
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

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...

如果您使用的是Windows，请安装预编译的Windows二进制文件。

例如来自Gohlke的Windows二进制文件的精彩目录：http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyzmq

Answer 2

我刚刚经历了同样的过程。正如PyZMQ Readme.md所说：

编译pyzmq时（例如在Linux上使用pip安装），通常建议通过自制软件，apt，yum等单独安装zeromq。如果这不可用，pyzmq将尝试将libzmq构建为Python扩展，虽然这不能保证有效。

在我的情况下，在你的情况下，它没有工作。您可以使用Cygwin安装zeromq或自行下载：http://zeromq.org/intro:get-the-software（我选择了最新的稳定版本4.0.4）

unztar，如果你愿意，可以配置（--prefix=/my/home/local），make install

然后你需要export PKG_CONFIG_PATH=/my/home/local/lib/pkgconfig（或者你的默认lib目录，例如/usr/local/lib/pkgconfig）。

确保此路径存在：

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

最后pip install pyzmq，它应该选择您刚刚构建的libzmq.pc文件。

easy_install pyzmq，cygwin。错误：安装脚本退出并显示错误：命令'gcc'失败，退出状态为1
