Could you tell me the version of pypy you used?

[katsar0v]

PyPy3.3 v5.5

[tk0miya]

We’re pleased to announce the release of PyPy3 v5.5.0. Coming four months after PyPy3.3 v5.2, it improves compatibility with Python 3.3 (3.3.5). We strongly recommend updating from previous PyPy3 versions.
http://doc.pypy.org/en/latest/release-pypy3.3-v5.5.0.html

The release announcement of pypy3.3-5.5.0 says it has compatibility with python 3.3.
But Sphinx no longer supports python3.3 since Sphinx-1.5.
If you want to use Sphinx with pypy, please use Sphinx-1.4.x series.

Thanks,

[katsar0v]
