... a solution to this. I would suggest looking on PyPI, the Python
Package Index, to see what you can get for Python 3. In your case, you
may well be in luck:
https://pypi.python.org/pypi/pyserial
There's a version that claims to work with any Python version (though
there's some minor disagreement; the metadata says 2.3-2.7 and
3.0-3.3, but the Windows binaries say 2.4-2.7 and 3.0-3.4). I suspect
the "2.7" in the name is actually the version of PySerial, and it's
coincidental that that happens also to be a Python version.
I think that you are correct. pyserial-2.7 is supposed to be compatible
with python3.
Since you seem to be on a POSIX system, you shouldn't need to worry
about the provided binary installers. Use pip3 to install it for your
Python 3, and you should be all set.
On further investigation, it turns out that I installed pyserial from my
distro's package manager. The default python is 3, with python2 being
the alternative. Now, to go with this, I'd installed python-pyserial,
not python2-pyserial:
==================================================
[root@automate ~]# pacman -Ss pyserial
community/python-pyserial 2.7-4 [installed]
Multiplatform Serial Port Module for Python
community/python2-pyserial 2.7-4
Multiplatform Serial Port Module for Python
==================================================
So, yes, my understanding is that the pyserial-2.7 which I have
installed should be compatible with Python3.
Now I have to work out how to make the report to Chris Liechti - I'll
try his gmx.net email address.
Thanks for all your advice - I'm enjoying my project, and loving Python!
Regards,
Peter.
