[Fab-user] fabric practically not working after installation on Mac OS 10.13.5

[Johannes Techel]

Hello,

I have a very basic problem with the fabric library, after I installed it
on my mac via pip.

$ pip install fabric

(I already tried it with sudo. Makes no difference)

Installation worked fine I think.

Johannes$ fab -V

Fabric 2.2.2

Paramiko 2.4.1

Invoke 1.1.1

Johannes$ python

Python 2.7.15 (default, Jul 23 2018, 21:27:06)

[GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.2)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

import fabric

As you see, my computer does find the module. But I can't do anything with
it...

If I follow the fabric tutorial (
http://docs.fabfile.org/en/1.14/tutorial.html), and try the very first step
-creating the fabfile.py with the hello task- It always fails with:

$ fab hello

No idea what 'hello' is!

I am in the right directory and the file exits. I followed exactly the
steps given in the tutorial.

I also asked a colleague of mine if it works on his machine. It also
doesn't.

Does anybody have a clue what the problem might be? I wasn't able to find a
solution anywhere online.

Cheers

Johannes

Hi Johannes,

Try running: pip install "fabric<2" - to get Fabric 1 :) you apparently
haven't pip installed it since 2.0 released! It's a major new release and
is backwards incompatible - see http://www.fabfile.org/upgrading.html for
details. More info on getting 1.x only is at
http://www.fabfile.org/installing-1.x.html .

I highly suggest updating your setup procedures to use a requirements.txt
or similar tactic for recording what versions of your dependencies are
known to work with your codebase(s) or workflows - see e.g.
https://pip.pypa.io/en/latest/user_guide/#requirements-files or
https://packaging.python.org/tutorials/managing-dependencies/ .

Best,
Jeff
