目前fabric1.x还不支持python3。虽然fabric官方称fabric2.x 会支持python3, 但至少目前还没有看到确切的时间。
在fabirc2.x发布之前，可以使用fabric3.
具体操作：
# 建立一个python3 的 virtualenv 环境
[root@centos]# mkvirtualenv py3.6.1env2 -p /root/.pyenv/versions/3.6.1/bin/python --no-site-packages
Running virtualenv with interpreter /root/.pyenv/versions/3.6.1/bin/python
Using base prefix '/root/.pyenv/versions/3.6.1'
New python executable in /root/.virtualenvs/py3.6.1env2/bin/python
Please make sure you remove any previous custom paths from your /root/.pydistutils.cfg file.
Installing setuptools, pip, wheel...done.
# 进入到建立的env 环境中
[root@centos]# workon py3.6.1env2
/root/.virtualenvs/py3.6.1env2/bin/python: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
# 使用 pip 安装 fabric3
(py3.6.1env2) [root@centos]# pip install fabric3

后续就可以在python3 的环境中正常使用 fabric 了
如果在 python2 下安装 fabric2, 也可以正常使用

Python 3 support for fabric
简介：
So until Fabric 2.0 will be ready, this package can be used instead :)
pip3 install fabric3
http://www.fabfile.org/roadmap.html
简介：
fabirc2 的发布情况。
https://github.com/mathiasertl/fabric
简介：
Fabric3 is a Python (2.7 or 3.4+) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks. This is a fork of the original Fabric (git) with the intention of providing support for Python3, while maintaining support for all non-archaic versions of Python2. Please see below for known differences with the upstream version of Fabric. To switch to Fabric3, simply do:
pip uninstall Fabricpip install Fabric3
https://pypi.python.org/pypi/Fabric3/1.13.1.post1
简介：
pypi上的fabric3.
Fabric3 is a fork of Fabric to provide compatability with Python 3.4+. The port still works with Python 2.7.
The goal is to stay 100% compatible with the original Fabric. Any new releases of Fabric will also be released here. Please file issues for any differences you find. Known differences are documented on github https://github.com/mathiasertl/fabric/
.
To find out what’s new in this version of Fabric, please see the changelog of the original Fabric.
For more information, please see the Fabric website or execute fab --help
