Unfortunately, Fabric has not yet officilly been ported to Python 3. However, it is possible to get it to work. Here is how I did it.
First, create a virtual environment to run fabric in. (If you haven't
set up virtual environments
for Python, go ahead and do that now, then come back.) I have the
[fink environment] (http://finkproject.org) installed on my Mac, and
the Python 3 executable is in /sw/bin/python3. If you have Python3
from homebrew or elsewhere, just put the correct path to the python3
executable after the --python switch below:
$ mkvirtualenv --python=/sw/bin/python3 fabric
[ ... ]
Save the following lines in a file /tmp/requirements.txt:
Babel==1.3
Jinja2==2.7.3
MarkupSafe==0.23
Pygments==2.0.2
Sphinx==1.3.1
alabaster==0.6.1
docutils==0.12
ecdsa==0.13
fudge==0.9.6
invocations==0.10.0
invoke==0.10.1
nose==1.3.6
paramiko==1.15.2
pycrypto==2.6.1
pytz==2015.2
releases==0.6.1
semantic-version==2.4.0
six==1.9.0
snowballstemmer==1.2.0
sphinx-rtd-theme==0.1.7
wheel==0.24.0
[Added 20150509] If you don't care about running fabric's unittests, you can actually get by with this list:
ecdsa
paramiko
six
In the fabric environment, install these packages:
(fabric)$ pip3 install -r /tmp/requirements.txt
Now, all you need is the last two requirements, which are not available from PyPi, because they are forked from the main developement line. Go to the place you store your github clones:
(fabric)$ cd ~/github
First, clone and install the Python 3 version of rudolf:
(fabric)$ git clone --depth=1 [email protected]:mok0/rudolf.git
(fabric)$ cd rudolf
(fabric)$ python3 setup.py install
(The --depth=1 switch gives a shallow clone. It is sufficient for most
cases, unless you are interested in the history of the repo.)
Next, clone the git repository from Sergey Pashinin, who has
ported fabric itself to Python 3:
(fabric)$ cd ~/github
(fabric)$ git clone --depth=1 [email protected]:pashinin/fabric.git
(fabric)$ cd fabric
See the tests, most of them run ok, but a few do fail :-(
(fabric)$ python3 setup.py nosetests
Even though some tests fail, fabric seems to work fine for most things I have tried. Build and install:
(fabric)$ python3 setup.py install
Now, test out your fabric installation. From the documentation,
try the following example. Place in /tmp/fabfile.py:
from fabric.api import run
def host_type():
run('uname -s')
Now try to run it on localhost (requires ssh):
(fabric)$ fab -H localhost host_type
[localhost] Executing task 'host_type'
[localhost] run: uname -s
[localhost] out: Darwin
[localhost] out:
Done.
Disconnecting from localhost... done.
(fabric)$
Deactivate the fabric enviroment:
(fabric)$ deactivate
$
Whenever you need to use your fabric installation, just issue the command:
$ workon fabric
(The latter requires that you have also installed virtualenvwrapper).
That's all, good luck!
