error using one-line installer

[MartijnZ]

Hi,

I tried to install the sr-ros-interface using the one line installer as indicated here "http://shadow-robot.readthedocs.org/en/latest/generated/shadow_robot/INSTALL.html"

I used the following command: curl -L bit.ly/dev-machine | bash -s -- -w ~{{ros_user}}/projects/shadow_robot/base

and expected that this would result in installing the project in my home folder.

During the installation process the following error appears:

 -------------------
 | Running Ansible |
 -------------------

ERROR! Unexpected Exception: No module named jinja2.exceptions
the full traceback was:

Traceback (most recent call last):

    mycli = getattr(__import__("ansible.cli.%s" % sub, fromlist=[myclass]), myclass)

    from jinja2.exceptions import UndefinedError
ImportError: No module named jinja2.exceptions

 | Install complete, please restart the machine |

Although the installer indicates that it is completed, I can't find the folder structure 'projects/shadow_robot/base' in my home folder. I also verified that the python module Jinja2 was installed (this was already the case).

Do anyone has any suggestions, what might went wrong?

Hi @MartijnZ Which version of Ubuntu do you have? What is your default Python version? What is default version of the PIP on your machine? Thank you

Hi AndriyPt,

Thank you for your quick response.

I use the following software: Ubuntu: 14.04.4 Python 3.4.4 Pip: 8.1.0 ROS: indigo 1.11.16

in our implementation of one-liner we are using Ansible which has following requirements http://docs.ansible.com/ansible/intro_installation.html#managed-node-requirements. "Python 3 is a slightly different language than Python 2 and most Python programs (including Ansible) are not switching over yet." So the easiest way is to switch to Python 2 and PIP for Python 2 by default and run one liner.
