#161 Pyserial 2.7 cannot be installed on a Python 3.3 installation

[Eric ALBER]

I'm trying to use pyserial 2.7 with Python 3.3 on Ubuntu 13.10.

I downloaded the sources and installed pyserial with the following command:

python3 setup.py install

I got the following warning:

/usr/lib/python3.3/distutils/dist.py:257: UserWarning: Unknown distribution option: 'use_2to3'

then when I 'import serial', I get the following error:

>>> import serial
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "./serial/__init__.py", line 21, in <module>
    from serial.serialposix import *
  File "./serial/serialposix.py", line 58
    except IOError, e:
              ^
SyntaxError: invalid syntax

It looks like 3to3 hasn't been applied

if I run

find serial -name "*.py" -exec 2to3 -n -w --no-diffs {} \;
python3 setup.py install

pyserial works properly

Installing using apt-get install python3-serial also works.

please try v3.0a0 from https://github.com/pyserial/pyserial/releases where Python 3 support was improved
