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
