However bundle finds the existing gems in the 2.0.0 path and does not try to install anything in the 2.3.0 paths. I would expect bundle to use the gem env to decide where to install things. However it does not seem to. [Later] I just realised that bundle is not one of the gems in 2.3.0, so I have just installed it.
