However Python 3.4 x86 ("C:\\Python34") works fine. The error looks like a problem with a compiler setup (just guess):

      File "C:\Python34-x64\lib\distutils\msvc9compiler.py", line 287, in query_vcvarsall
        raise ValueError(str(list(result.keys())))
    ValueError: ['path']

The failed job: https://ci.appveyor.com/project/tarantool/tarantool-python/builds/3...

There is the discussion regarding a problem with Python 2.7.10 that looks similar and was resolved.

I guess the problem can be reprodured with the following appveyor.yml (it is my appveyor.yml, but stripped):

    - PYTHON: "C:\\Python34-x64"

  - "%PYTHON%\\python.exe -m pip install pyyaml"

build: off

  - echo This will not be executed

    Worked around by explicitly requiring PyYAML version that has wheel on PyPI for given platform and Python version / build.
