Cygwin - How to install ansible?

Question

How to get / install ansible using Cygwin?

I tried the following steps but it's didn't work during bullet 5 (while running "python setup.py install"). Steps taken from: Taken from https://servercheck.in/blog/running-ansible-within-windows

1) Download and install Cygwin, with at least the following packages selected (you can select the packages during the install process):

libyaml
libyaml-devel
curl
python (2.7.x)
python-crypto
python-openssl
python-paramiko
python-setuptools
git (2.1.x)
vim
openssh
openssl
openssl-devel

2) Download and install PyYAML and Jinja2, as they're not available via Cygwin's installer:

1. Open Cygwin
2. Download PyYAML:
    curl -O https://pypi.python.org/packages/source/P/PyYAML/PyYAML-3.10.tar.gz
3. Download Jinja2:
    curl -O https://pypi.python.org/packages/source/J/Jinja2/Jinja2-2.6.tar.gz
4. Untar both downloads:
    tar -xvf PyYAML-3.10.tar.gz && tar -xvf Jinja2-2.6.tar.gz
5. Change directory into each of the expanded folders and run python "python setup.py install" to install each package.
6. Clone ansible from its repository on GitHub:
    git clone https://github.com/ansible/ansible /opt/ansible
    This was tested with Ansible version v1.6.6, change directory into /opt/ansible and checkout the correct tag: git checkout v1.6.6.
7. Add the following lines into your Cygwin .bash_profile:
    # Ansible settings
    ANSIBLE=/opt/ansible
    export PATH=$PATH:$ANSIBLE/bin
    export PYTHONPATH=$ANSIBLE/lib
    export ANSIBLE_LIBRARY=$ANSIBLE/library

8. At this point, you should be able to run ansible commands via Cygwin (once you restart, or enter source ~/.bash_profile to pick up the settings you just added). 
    Try ansible --version to display Ansible's version.

9. Passwordless ssh will need to be set up between your Windows machine and the deployment host(s)
    To enable passwordless ssh on Centos -  ssh-copy-id root@node
    To enable passwordless ssh on SuSE I followed the steps in this blog:
    http://www.firedaemon.com/blog/passwordless-root-ssh-public-key-authentication-on-centos-6
    install sshpass v1.05 on your Windows machine<br>

The error that I got during during bullet 5 is:

Answer 1

With later installer https://cygwin.com/setup-x86_64.exe you can install ansible and ansible-doc directly. Just select it from the list and set to install.

Answer 2

Steps for Ansible 2.7.6 and Python3 and Cygwin 2.11.2(0.329/5/3)

1. Having Cygwin installed
2. Install python3

c:\cygwin64-setup>setup-x86_64.exe -q -P python3
$ python3 --version

3. Install pip

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
$ python3 get-pip.py
$ pip --version

4. Install dev tools (for Ansible)

c:\cygwin64-setup>setup-x86_64.exe -q -P make
c:\cygwin64-setup>setup-x86_64.exe -q -P gcc-g++
c:\cygwin64-setup>setup-x86_64.exe -q -P python3-devel
c:\cygwin64-setup>setup-x86_64.exe -q -P libffi-devel
c:\cygwin64-setup>setup-x86_64.exe -q -P openssl-devel
c:\cygwin64-setup>setup-x86_64.exe -q -P openssh

5. Install ansible

$ pip install ansible
$ ansible --version

6. Check which ssh is used (https://serverfault.com/a/913435)

% which ssh
/cygdrive/c/WINDOWS/System32/OpenSSH/ssh

Note: if not cygwin ssh is used (like above) change env PATH variable for cygwin or change Ansible inventory hosts file items with flag ansible_ssh_executable=/usr/bin/ssh
