sh: test: argument expected and os.environ

[Iván Cabria]

Hi, 
 
thanks to Jeff Epler for the answer. 
 
I have tried his suggestion and I have added two lines after the  
first line in the python script: 
import os 
os.environ['SHELL'] = "/bin/bash" 
 
 
The first three lines of the python script are now: 
#!/usr/bin/env python 
import os 
os.environ['SHELL'] = "/bin/bash" 
 
 
I have run the script and I have got the same message error than before: 
sh: test: argument expected
