Trouble installing ZeroMQ / pyzmq in Windows, using pip

Question

I'm kinda new to python and I'm using pip to install packages via console. Worked well with previous installs, but when I try to install pyzmq I receive an error message. I thought the problem was realted to Cython (since I've previously seen something like that), but then I installed Cython and the problem persists. This is the full message I get:

      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 >= 3.2 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...

Since I've noticed an error about MS C++, I downloaded and installed basically everything I could related to Microsoft visual C++, but the error persists.

Also tried to install pyzmq via the msi file, but I'm not sure about the correct path.

Answer 1

I figured it out!

I installed Visual Studio, but that was not enough. I needed the Build Tools too, more specifically, everything that had "C++" on the optional packages during the install. After that I could install the packages with no problem.
