Often happens that users don't read thoroughly the support policy and install the wrong Ignition distribution. When this happens, importing
scenario
fails with arcane error on shared libraries not found.This PR implements a new feature that should provide a more explanatory error message to the users in this case. It covers both cases in which the
ign
command does not exists in PATH (i.e. either Ignition is not installed or the environment is not properly configured) and ifign gazebo --versions
returns a failing exit code (to be future proof in case the command line changes in next versions).From the python side, we exploit the
packaging
package.
