Description

What steps will reproduce the problem?

Installed spyder-terminal, via anaconda3 64b, to spyder4, and started spyder. Startup ends with Spyder Terminal Error popup. Followed instruction to debug spyder; got an error file, terminal output in terminal window, and an empty terminal_out.log file.

Terminal Edrror log:
