For example, when I want to use this tool for registration, there is an error. I have tried many cases and the data are the same. Could someone please help me solve it? The error code is as follows:

I am MAC version 5.50, and the elastix plug-in version is the latest.`

@xiangchaodong1 Does registration work with default settings on the `MRBrainTumor1` and `MRBrainTumor2` data sets?

@pieper, @jcfr or others who have access to a mac: could you check that Elastix (and in general, C++ modules in extensions) work well in Slicer-5.4/5.5 on macOS?  
Today I helped someone on a macOS computer and there were a number of errors about some shared libraries in extensions could not be loaded.

Yes, I’ve confirmed VMTK is broken too.

This is a very significant issue with the 5.4 release then.

@jcfr Could you have a look at this?

Yes, the default registration: General Registration (BRIAN) can be used, but I am not skilled in using it.
