ModuleNotFoundError: No module named '_posixsubprocess' when creating virtual enviroment

Question

i'm trying to set a virtual enviroment with:

$ python3 -m venv cv2

But when trying it, i'm getting this exception:

    Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 183, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/lib/python3.6/runpy.py", line 142, in _get_module_details
    return _get_module_details(pkg_main_name, error)

    import _posixsubprocess

Error in sys.excepthook:

  File "/usr/lib/python3.6/subprocess.py", line 136, in <module>
    import _posixsubprocess
ModuleNotFoundError: No module named '_posixsubprocess'

Original exception was:
Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 183, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)

    import _posixsubprocess
ModuleNotFoundError: No module named '_posixsubprocess'

I've trying reinstalling subprocess32, but i haven't solved anything. I'm using Python 3.6.3 Anaconda on Ubuntu 18.04.1 LTS. Any suggestions?

Answer 1

1. pip uninstall subprocess32.
2. Use the built-in subprocess module: In your Python code, just import subprocess directly. The built-in module has all the functionality you need.
3. pip3 install virtualenv or pip3 install virtualenvwrapper.
4. python3 -m venv my-project-env.
5. And it should be activated on virtualenv in source my-project-env/bin/activate
