Install Subprocess Module Python

Sep 18, 2017 - Hi All, Thank for the recent replies. I want to use the module b/c per the docs os.system is antiquated and cannot use more than.


Pip is not able to find this module, as well as me on pypi website. Could you please tell me the secret, how to install it? I need the module to spawn new shell process via I have seen a lot of examples, where people use import subprocess, but no one shows how it was installed. Error, that i got (just in case i've lost my mind and does not understand what is going on): Microsoft Windows [Version 6.3.9600] (c) 2013 Microsoft Corporation. All rights reserved. C: Users Alexander Desktop tests-runner>python Traceback (most recent call last): File '', line 165, in main() File '', line 27, in main'py.test') File 'C: Python27 lib', line 522, in call return Popen(*popenargs, **kwargs).wait() File 'C: Python27 lib', line 710, in __init__ errread, errwrite) File 'C: Python27 lib', line 958, in _execute_child startupinfo) WindowsError: [Error 2] The system cannot find the file specified.

There is no need to install this module in Python 2.7. It is a standard module that is built in. The shows that it was added to the library for Python version 2.4.

It's been with us for a long time now. The error that you show in your question update is nothing more prosaic than a file not found error.

Likely the executable file that you are attempting to call Popen on cannot be found. That traceback indicates that subprocess is installed and has been imported. The problem is simply that the call to'py.test') is failing. For future reference, this is the type of traceback you encounter when attempting to import a module that has not been installed: >>> import foo Traceback (most recent call last): File ', line 1, in ImportError: No module named foo.
