`pip install pyyaml` fails in AppVeyor on 64-bit Python 3.4 with the
following message (full log is in [1]):

 | Collecting pyyaml
 |   Downloading <...>/PyYAML-5.3.1.tar.gz (269kB)
 | <...>
 | building '_yaml' extension
 | Traceback (most recent call last):
 |   <...>
 |   File "C:\Python34-x64\lib\distutils\msvc9compiler.py", line 287, in query_vcvarsall
 |     raise ValueError(str(list(result.keys())))
 | ValueError: ['path']

It is cumulative effect of several problems.

The first one is that pip does not choose a PyYAML version, which
supports given Python version (it is PyYAML 5.2, see [2]), but tries to
install a last one (it is PyYAML 5.3.1 ATM). There are PyYAML issues
[3], [4] and [5], which are not exacly about this, but looks tightly
related. Despite Python 3.4 is not officially supported in PyYAML, it
works on 3.4 in fact, so it is not the problem per se.

Next, there are no wheels for Python 3.4 for PyYAML 5.3.1 on PyPI (which
is logical), so pip downloads the source tarball and tries to build it.
And the exception shown above is raised.

It looks similar to [6], so I would guess that it is a compiler setup
problem within an AppVeyor Windows image. I started the discussion [7]
regarding it, but we need to work the problem around.

Side note: 32-bit Python 3.4 works fine, the problem appears only for
the 64-bit Python 3.4 build.

In order to workaround the compiler setup problem we can just choose a
PyYAML version for which PyPI provides wheels for the corresponding
platform / Python version / Python build. It is 5.2b1, see [8].

Python 3.4 reaches EOL 2019-03-18 with releasing 3.4.10 (see [9]). I
would not consider it as the reason to drop support of it on our side,
especially when we're tell about a library (our users has its users,
etc) and it is hard to estimate the impact. The problem we meet here is
just about a testing dependency in a particular environment. So let's
keep Python 3.4 support until there will be a better reason to stop.
