Python - No module named 'fabric.api - Windows 10

Question

I just installed Python 3.7 and Fabric.

It works perfectly on my laptop, but not on my desktop.

The error :

Traceback (most recent call last):
File "C:\Program Files (x86)\Python37-32\lib\runpy.py", line 193, in _run_module_as_main

ModuleNotFoundError: No module named 'fabric.api'

But Fabric seem to be installed ?

C:\Users\MyUser>pip install fabric
Requirement already satisfied: fabric in c:\program files (x86)\python37 32\lib\site-packages (2.4.0)

However "fabric" didn't appear in the list when I do the following in idle (just Fabfile) :

>>> import pkgutil
>>> [name for _, name, _ in pkgutil.iter_modules()]
['fabfile', '_asyncio', '_bz2', ... 'enum', 'filecmp', 'fileinput', ...]

I also tried to uninstall/reinstall fabric, but it's still failing.

Do you have any idea why I cannot import fabric.api ?

Update :

I also created a virtual environment :

py -3 -m venv env 
code . 

Selected Python interpreter "venv" in Visual Studio code then :

python -m pip install fabric 

But i'm still facing the same error :-/

Well after few research I finally found a workaround by using fabric3 (a fork of Fabric, compatible python 3).

pip uninstall fabric
pip install fabric3

Link : https://pypi.org/project/Fabric3/

I see you have already installed fabric 2.4.0 which is great! Since you are using the fabric 2.4.0 you can't use from fabric.api import taks. fabric.api could be used if you use fabric1xx

If you want to import connection and task from fabric2.4.0 you have to do it like this

from fabric import Connection as connection, task

@task
def deploy(ctx):
    with connection(host=host, user=user) as c:
         c.run('ls -la')

Note: fabric 3 is not an official fork. I advise you to use fabric2.4.0
