I did the usual brew cask cleanup and brew cask doctor but still no success. It is just me?

@ccordoba12 mentioned in #8130 that Spyder is released in both Python2 and Python3 versions but Cask only seems to have a formula for the Python2 version.

The most recent release appears to be 2.7-only; I am not sure whether future versions will remain so.

Here, we would welcome feedback from the Spyder maintainers to decide on a course of action, since switching payloads between versions is highly undesirable.

I'm sorry for not releasing more dmg's for Python 3. They are only working correctly on 10.7, which is where I generate them.

On other Mac versions, it's not possible to start Python nor IPython consoles, which is a major drawback for our users.

We think that's caused by a bug in py2app, but we're still investigating about it :-)

@ndr-qef The fix above did not solve the problem when I made that change to /usr/local/Cellar/brew-cask/0.53.3/Casks/spyder.rb and tried the install again.

@ccordoba12 An alternative to py2app is PyInstaller which makes .exe on Windows and .app on Macs.

@ccordoba12, thanks for your reply, and not to worry. It is certainly sensible to only provide releases which work on recent OS X versions.

We will keep our package on Python 2 for the near future; later on, we can reconsider the problem according to your recommendations.

@cclauss, the cask works on my machine. Could you run brew update and attempt the conventional brew cask install spyder?

[cclauss]

That works! Thanks much!

Hey guys, I released a new dmg for Python 3 which, according to two different sources, is working correctly now.

But I'd like to ask you to demand for this one a Mac version higher than or at least equal to 10.9. It won't work on older versions, so I don't want to deal with bug reports for them :-)

However, our Python 2.7 dmg works with 10.7 and higher :-)

Thanks.
