open python script in virtualenv from python script

Question

I want to open a python script from an other python scrip but in the virtualenv I tried os.system and subprocess.call but they couldn't open the virtualenv

os.system("workon cv") warning:

sh: 1: workon: not found

cmd = 'workon cv'

subprocess.call(cmd.split())     error:

    OSError: [Errno 2] No such file or directory

you could wrap it in a module, place the module in the script folder or add the path to the module to the python path and import it. — Moritz

Have you tried adding the full path to the 'workon' binary ? Or if it's an alias for something else like virtualenv activate then do os.system('/usr/bin/virtualenv activate cv') ? — Alan Kavanagh

workon is not a program but a shell function from virtualenvwrapper. You cannot call it in a subprocess because it changes the current shell environment.

I solved the problem:

the python script where I want to call the other python script should be opened in the virtualenv
put all the code in main function and import the file: import FileName

then call the main function: FileName.main()
