A powerful free-kick from Michel Bastos on 74 minutes cancelled out Cedric Barbosa's 57th-minute opener to move Lyon onto seven points from three games.
Evian, who finished ninth last May, won their first point of the season.

Both sides had chances to score a late winner but lacked the cutting-edge.
