NewConstraint returns nil

[fi0rini]

Hello, semver.NewConstraint returns err for >= 1.3.1 < 2

c, err := semver.NewConstraint(">= 1.3.1 < 2")

(Hope I'm not stepping on any toes here...)

I think you need a comma between the two constraints, i.e.

c, err := semver.NewConstraint(">= 1.3.1, < 2")

@nic-fio multiple constraints needs to be separated by a comma as @ae-dg pointed out. Since this has been answered I'm going to close the issue. If you have any further needs please feel free to open a new issue or re-open this one.
