    Already up-to-date.
    Depuis GitHub - frappe/frappe: Low code web framework for real world applications, in Python and Javascript

    subprocess.CalledProcessError: Command ‘./env/bin/pip install -q -r ./apps/erpnext/requirements.txt’ returned non-zero exit status 127

Or if I execute Bench restart :

frappe-web: stopped
frappe-workerbeat: ERROR (abnormal termination)
frappe-worker: ERROR (abnormal termination)
frappe-web: started
