Valid constraints fails to parse

[Andrew Henry]

When using the following valid semver range: 2 >=2.7.0, it fails to parse this as a constraint

package main

import (
	"fmt"
	"github.com/Masterminds/semver"
)

func main() {
	_, err := semver.NewConstraint("2 >=2.7.0")
	if err != nil {
		fmt.Println(err.Error())
	}
}

Outputs the following:

improper constraint: 2 >=2.7.0

But this range is valid and equates to >=2.0.0 <3.0.0-0 >=2.7.0 via semver check

The issue here is that you're using semver version 1. You needed a comma to separate them for that version. TO use v3, the current supported version try updating your imports to...

import (
	"fmt"
	"github.com/Masterminds/semver/v3"
)
