Strangely, this demo works after kiwisolver is installed... this solution is not really described by the error raised... Currently, the error message mentioned that the "kiwisolver" is not installed, while also points to unable to import ConstraintsContainer from enable.api. Which is ok but a little confusing, should we change this or not?
Isn't this the exact same issue as #1018?

Yeah, correct. Almost forgot I was solving this issue. The new error message we introduced turned out to be useful then. : ) I will go ahead and close this
