Description of your problem

What steps will reproduce the problem?

1. as clean an install of this spyder version as i can make it, spyder --reset, spyder --default, etc.
2. run any code from the editor via F5 key (or button, etc) e.g. print("test") in temp.py

What is the expected output? What do you see instead?

the code in the editor should run but the following is generated:

runfile('/path/to/temp.py', wdir='/path/to')
Traceback (most recent call last):

File "", line 1, in
runfile('/path/to/temp.py', wdir='/path/to')

NameError: name 'runfile' is not defined

Please provide any additional information below
"import spyder.widgets.externalshell" from the console will fix this bug (something missing in an init.py file?)
