[FIXED] Spyder reports invalid alias when running any script

Issue

I can't tell why this is happening but it seems to have started when I updated (everything - conda update --all). It had been about 1 year since I last had updated. Something must have changed.

Here is the script:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
"""
Created on Sun Mar  3 11:25:22 2019

@author: pitosalas
"""

print("hello")

And here is the output from pressing the green triangle in spyder:

Python 3.6.6 |Anaconda, Inc.| (default, Jun 28 2018, 11:07:29)
Type "copyright", "credits" or "license" for more information.

IPython 7.3.0 -- An enhanced Interactive Python.

Solution

As indicated on the issue tracker, IPython 7.7.0 sorted out this problem. I can confirm updating to 7.7.0 worked for me (conda 4.7.10 on Ubuntu 18.04, Spyder 3.3.6).
