Run React bug

[August7337]

Hello I have a problem with react when I tryto run my web application an error appears:

codespaces-react@0.1.0 start
BROWSER=none WDS_SOCKET_PORT=0 react-scripts start

'BROWSER' n’est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes.
Waiting for the debugger to disconnect...
