Build: Python package conflicts stop build

[kwokcb]

Issue

It seems that if Python install finds conflicting packages to the current version of MaterialX that it will stop the build.
It might have previously silently let this go by before ?

Though it is possible to run a "clean" virtual env, is there a way to not stop the build if such conflicts are found ?

e.g. local log:

  Installing collected packages: MaterialX
EXEC : error : pip's dependency resolver does not currently take into account all the packages that are installed. This
 behaviour is the source of the following dependency conflicts. [D:\Work\materialx\bernard_MaterialX\build\install.vcxp
