New ticket #4762 by jeffdn
For Beanbag, Inc. > RBTools

Status: New
Tags: Priority:Medium, Type:Defect


------------------------------------------------------------------------------
The encoding argument to subprocess.Popen was only added in Python 3.6
==============================================================================

# What version are you running?
1.0.1

# What steps will reproduce the problem?
1. using a version of Python 3 before Python 3.6 (Python 3.5 in our case)
2. try to call RBTools
3. watch it blow up!


# What is the expected output? What do you see instead?
The RBTools code checks for Python 3, and if it exists, calls 
`subprocess.Popen` with an encoding keyword argument. This argument can only be 
used in version Python 3.6 and later.

# What operating system are you using?
MacOS X 10.14

# Attach the debug out from the command.

```
