Failure with Python 2.7 about appveyor-ci HOT 4 OPEN

The same issue with openalea.core:

conda.exe build --python=2. ..\conda

The PYTHON VERSION is wrong (2. rather than 27)
Use the CONDA_PY env var instead:
doc

from appveyor-ci.

@pradal Normally PYTHON_VERSION should be formatted as 2.7 while CONDA_PY should be 27.
CONDA_PY should be set as env variable while PYTHON_VERSION is passed as argument to conda build --python.
It seems that default detection of PYTHON_VERSION is buggy and should not gives 2.

from appveyor-ci.

Look at upstream repo:
Pierre add a file python_version.py.

And it call the generated script in the build_script

from appveyor-ci.

But if I set PYTHON_VERSION, I have yet the error.
It is just afer

Configuring Windows SDK "v7.0" for Python 2 on a 64 bit architecture
Setting SDK environment relative to C:\Program Files\Microsoft SDKs\Windows\v7.0.
Targeting Windows 7 x64 RELEASE

Perhaps this disable the conda env?

from appveyor-ci.
