Can you please post the full output: from the line where you created the virtualenv down to where your shell resumed control after installing Cactus?

Thanks!

[foxmask]

I updated the original post

@foxmask:

`Successfully installed cactus colorama argparse keyring tornado colorlog boto django-markwhat Django six markdown2 backports-abc``

The error you're seeing is a warning. It's not an error. Try running cactus, it should work just fine.

Cheers,

[foxmask]

so you ignore the line 42 in the plugin file haml.disabled.py ?

[krallin]

@foxmask

If you do try using the haml plugin, then that will not work. You'll get a syntax error and a crah.

However, unless you enable that plugin, that file is never going to be run, so the fact that it doesn't work under Python 3 isn't going to be a problem.

The reason why you're seeing an error is because pip attempted to compile all the py files it found when it installed Cactus, and that one failed because that one doesn't work in Python 3.

But in practice, you're probably not using the haml plugin, so you don't need to care.

Cheers,
