Cada vez que instales un **nuevo paquete** en ese entorno, **activa** el entorno de nuevo.

Esto asegura que si usas un programa de **terminal (<abbr title="command line interface">CLI</abbr>)** instalado por ese paquete, uses el de tu entorno virtual y no cualquier otro que podría estar instalado globalmente, probablemente con una versión diferente a la que necesitas.
