Invalid version string "~4.*"

[HuckinB]

After running composer require devdojo/chatter
I recieve
`[RuntimeException]
Could not load package luketowers/purifier in http://repo.packagist.org: [UnexpectedValueException] Could not parse version constraint ~4.: Invalid version string "~4."

[UnexpectedValueException]
Could not parse version constraint ~4.: Invalid version string "~4." `

Any ideas how to resolve?
