New in pytest 2.6.0, many setuptools tests are failing thus: https://travis-ci.org/jaraco/setuptools/jobs/31453603

In particular, the error occurs with this traceback:

c:\python\lib\distutils\log.py:44: in info
    self._log(INFO, msg, args)
c:\python\lib\distutils\log.py:30: in _log
    if stream.errors == 'strict':
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

self = <_pytest.capture.EncodedFile object at 0x0000000005C87128>
name = 'errors'

    def __getattr__(self, name):
>       return getattr(self.buffer, name)
E       AttributeError: '_io.FileIO' object has no attribute 'errors'

c:\python\lib\site-packages\pytest-2.6.0-py3.4.egg\_pytest\capture.py:242: AttributeError

Using Python 2.x or pytest 2.5.x works around the issue.

The capturing stream is a kind of a "pseudo" stream. The error probably goes away if you disable output capturing with -s. I guess we need to work harder and maybe provide an "errors" attribute on the capture-stream.

i have a fix which just sets "errors='strict'" on the EncodedFile internal stream. Could you try it out? you can install via "pip install --pre -i https://devpi.net/hpk/dev/ pytest" (should give you 2.6.1.dev3). Want to release pytest-2.6.1 anytime now so feedback very welcome.

the links you had don't seem to use 2.6.1.dev3 but rather 2.6.0 -- but could you elaborate in any case?

I failed to include --upgrade in the installation of pytest, so the dependency was satisfied and didn't get the patch.

It's definitely fixed now. (sorry for the noise)

fix issue555: just add "errors" attribute to internal Capture stream.
