Missing Comma Should Warn/Error

[George-Ogden]

Description

Recently, I wanted to limit a plotly version, which I did with plotly>=5.24.0<6. This is missing a comma and should say plotly>=5.24.0,<6. However, it installed plotly>6 without error or warning.

Expected behavior

I think it would be best if this generated an error or warning. Ideally, this would be an error, but if 5.24.0<6 is a valid version, a warning would also be possible. This could be extended to other cases, such as plotly>=5.24.0<6.
