build recipe just for python2.7?

[Chris Barker]

I"m tryin gto specify that a recipe for aqpyton padakge only support py2 (or py2.7)

I find I can do:

requirements:

  build:

    - python ==2.7.10

but It doesn't seem to like:

 - python ==2.7

I dont want to do:

 - python >= 2.7

as that would imply py3 as well, which I really don't want.

Given that python2.7 is at the end of it's life, specifying 2.7.10 is probably fine, but how to do this in general? Like what about python3.4, but not 3.5??

can I do a >= and a < ???

Thanks,

  -Chris

I think I answered my own question:

requirements:

  build:

    - python >=2.7,<3 

seems to be working.

In your conda build recipe, you shouldn't specify any Python version.  Simply:

requirements:

  build:

    - python

By default conda-build will use Python version of the Python in the root environment, but this can also be changed by setting the CONDA_PY environment variable, or using the --python option.

This way the recipe is independent of the Python version, and can be used to build multiple packages against different versions of Python.

well, that's a nice theory ,but if if it can't be built / won't work with certain python versions, it's nice to be able to specify that in the yaml...

though I've found a work-around for the issue at hand.

You can specify this in the `meta.yaml`, if you really want.  By:
```

build:

  skip: True        [py == 27]

```

cool -- though woulnd't that be:

  skip: True        [py != 27]

?

Yeah!  It would skip, unless the python version is 2.7.  Good catch.
