I am trying build gym-ignition from source make command does NOT works, I am using Ros2-Dashing and Ros-Melodic on ubuntu 18 bionic

Can you please take the time to fill the information of the Bug report issue template first? I cannot guess what version you are trying to install against which Ignition distribution.

kashifzr · 2021-10-12T16:38:42Z

@diegoferigo my apologies for incomplete references
Actually i am trying to build gym-ignition package, for building ign_moveit2. When I am installing on Ubuntu 20.04 Focal Fossa using pip install gym-ignition then I am facing libignition-gazebo6.so.6 missing as Import Error. I am using Gazebo11

diegoferigo · 2021-10-13T07:08:49Z

ScenarIO is compatible only with Ignition Gazebo (Fortress) and not Gazebo Classic (11). They are two different piece of software, you can read more here.

Once you have Ignition (Fortress) installed in your system, you can build the project from sources. If you want to use the binary wheel distributed on PyPI, only Ubuntu Focal is supported. However, also in this case, you must install first manually Ignition Gazebo Fortress, otherwise you get the error about the missing shared library. Apparently the logic of #399 is not fully working.

kashifzr · 2021-10-18T10:11:15Z

@diegoferigo Please have a look at this issue

What is the output of: ign gazebo --versions?

kashifzr · 2021-10-18T11:33:59Z

My apology for being late, Actually I was installing it and it took so much time

I did installed ign gazebo which in the include path it is show as ign-gazebo-7 but when I try to see this command it does not work

isr@isr-MS-7A64:/usr/local/lib/ign-gazebo-7$ ls
plugins
isr@isr-MS-7A64:/usr/local/lib/ign-gazebo-7$

diegoferigo · 2021-10-18T11:59:07Z

It's yet not clear to me how you configured your system (exact sequence of commands you used to install the packages). You can use the osrf's ubuntu ppa to install Ignition Fortress (6), that is the only supported version for the Stable channel of ScenarIO / gym-ignition.

kashifzr · 2021-10-19T08:26:32Z

@diegoferigo
For the issue I did install ignition Fortress where the output of ign gazebo --version is given like this, Even the GUI for ign gazebo appear just like normal Gazebo.

However the problem to import gym_ignition and scenario is still. I personally remove both packages and install them

I am using https://ignitionrobotics.org/docs/fortress/install_ubuntu_src

From the error you posted in #403 (comment), it seems that the ign gazebo --versions output cannot be parsed by Python. I was suspecting to a strange output, but it looks good to me. Can you provide the output of the following? It is an extract of the logic that is failing on your setup.

import packaging.specifiers
import packaging.version


def supported_versions_specifier_set() -> packaging.specifiers.SpecifierSet:

    # If 6 is the Ignition distribution major version, the following specifier enables
    # the compatibility with all the following versions:
    #
    # 6.Y.Z.devK
    # 6.Y.Z.alphaK
    # 6.Y.Z.betaK
    # 6.Y.Z.rcK
    # 6.Y.Z.preK
    # 6.Y.Z.postK
    #
    return packaging.specifiers.SpecifierSet("~=6.0.0.dev")

Btw, from this log extracted from your previous comment it seems to me that you had two different Ignition distributions installed in your system:

Traceback (most recent call last):
  File "/home/isr/.local/lib/python3.8/site-packages/scenario/__init__.py", line 137, in check_gazebo_installation
    gazebo_version_parsed = packaging.version.Version(
  File "/usr/lib/python3/dist-packages/packaging/version.py", line 277, in __init__
    raise InvalidVersion("Invalid version: '{0}'".format(version))
packaging.version.InvalidVersion: Invalid version: '6.0.0
5.1.0'

Something that changed in #403 (comment).

From your list of steps, I would really recommend to use virtual environments and not the ~/.local folder. Furthermore, you can also install Ignition from debs if you prefer, no need to compile from colcon unless you need it for other reasons.
