How to overcome - pip install ansible on windows f

Question

how to fix the pip install failures on windows with below error. Getting this error while trying to install ansible.

I suspect it is with issue with selected pip package for install. but the same is working fine with Linux based systems. Will there be any difference with OS for pip install

Exception:

Answer 1

I got ansible installed without using pip, which seemed pretty straight forward to me.

Steps:

• download compressed .tgz archive from https://pypi.org/project/ansible/

• open 7-zip with right-click run as administrator and extract. <- admin is necessary because of symbolic links

• opened an admin console in the folder and ran:

  python setup.py install

now ansible is installed on Windows.

Answer 2

Well, it seems to be a known bug:

https://github.com/ansible/ansible/issues/31419

In Ansible 2.4.0, the module copy use symbolic links in the tests suite: https://github.com/ansible/ansible/tree/devel/test/integration/targets/copy/files/subdir/subdir1

circles -> ../
subdir3 -> ../subdir2/subdir3

Windows 10, cannot create this directories tree because the path is too long. In fact the resolved path is:

test/integration/targets/copy/files/subdir/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir1/circles/subdir2/subdir3/

bug report ends with:

We do not support installing ansible directly on a windows machine. You will need a linux like operating system to install ansible on

Workaround

A possible workaround is to download the wheel on pypi, it doesn't depend on Linux or whatever, probably pure python:

https://pypi.python.org/pypi/ansible/2.5.0a

(the pip install ansible command downloads the "source" .tgz archive, performs tests, ... and the path issue is within the tests, so let's use a ready-to-use pre-built bundle)

Once downloaded, use pip install path/to/the/wheel/file.whl

Tested and installed successfully on my Windows 10 machine:

C:\Users\jotd>c:\Python27\Scripts\pip install C:\Users\jotd\Downloads\ansible-2.5.0a1-py2-none-any.whl
Processing c:\users\jotd\downloads\ansible-2.5.0a1-py2-none-any.whl
Requirement already satisfied: PyYAML in c:\python27\lib\site-packages (from ansible==2.5.0a1)

ok, installed, but let's try to import it:

C:\Users\jotd>c:\python27\python
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:24:40) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import ansible
>>>

works! yay!

Answer 3

I also ran into problems installing ansible on windows. Instead of trying to install ansible on a platform it isn't meant for I suggest enabling the windows ubuntu subsystem.

See https://tutorials.ubuntu.com/tutorial/tutorial-ubuntu-on-windows

Once you do that install ansible through apt-get or pip.

Installing with PIP:

Make sure you have python3-disutils first:

sudo apt install python3-distutils

and then install pip as per https://pip.pypa.io/en/stable/installing/

Try running ansible - if it cant be found you need to add site-packages directory to your $PATH.

To avoid all this installation work I suggest using apt-get.
