Hi, After installing pypy 4.0.1 on FreeBSD (from ports), I get the above exception when trying to install setuptools, or when installing anything with pip (after pypy -m ensurepip). This all worked with the previous version (2.6). I could find this problem elsewhere: http://stackoverflow.com/questions/34566676/failed-to-install-pip-for-pypy-o... so it doesn't seem to be related to FreeBSD. An example full trace: # pypy -m pip install --upgrade pip You are using pip version 6.1.1, however version 8.0.0 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

Returning None here is fine according to the docs, but the above code snippet doesn't handle the TypeError, which it gets when doing path.decode(None). How this could work? On pypy 2.6 on the same machine: Python 2.7.9 (295ee98b69288471b0fcf2e0ede82ce5209eb90b, Jun 12 2015, 19:25:58) [PyPy 2.6.0] on freebsd10 Type "help", "copyright", "credits" or "license" for more information.

'test'.decode(None) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: expected string, got NoneType object

Unhandled TypeError exception! python 2.7 works the same way:

...

...

'test'.decode(None) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: decode() argument 1 must be string, not None

Which installs setuptools just fine (although it doesn't get to the above snippet, because it doesn't return None to sys.getfilesystemencoding()). If I set fs_enc to None in the above snippet, even python 2.7 fails. So the key here (if I'm not completely lost) seems to be not returning None to the getfilesystemencoding to fix broken(?) software. What do you think about this? Thanks,
