Python 3: TypeError: __init__() got an unexpected keyword argument 'encoding'

[unix-junkie]

I'm trying to run compiledb (the Python 3 version) on a Debian 9 box:

$ compiledb make
## Building [make]...
cc -I/usr/local/include   -c -o xpickrgb.o xpickrgb.c
cc -o xpickrgb -L/usr/local/lib xpickrgb.o -lX11 -lm -lc

Traceback (most recent call last):

    sys.exit(cli())

    return Popen(cmd, encoding=encoding, **kwargs)

Python version is:

$ python3 -V
Python 3.5.3

When using the Python 2 version, there's no such error, and compiledb works correctly.

Just to clarify, what version of compiledb are you running?

pip3 freeze | grep compiledb

[unix-junkie]

It's version 0.9.8:

$ pip3 freeze | grep compiledb
compiledb==0.9.8

Strangely, the Python 2 version is slightly newer:

$ pip freeze | grep compiledb
compiledb==0.10.1

[agnjunio]

There were a recent patch to fix the issue you mentioned. Probably the fix is in the latest version (0.10.1). Try to have it installed on your python 3 version:

pip3 install compiledb --upgrade

[unix-junkie]

@agnjunio Unfortunately, it's still version 0.9.8:

$ pip3 install compiledb --upgrade --no-cache-dir

So, I made some initial testing and saw that your Python 3.5.x version is currently not supported by the versions listed in setup.py. Maybe that's why you can't upgrade to 0.10.1.

I will dig a little bit more to find out why versions 3.0-3.5 aren't passing in the tests.
