y el composer install me pide usuario:
guarani3b-desa:/usr/local/proyectos/g3w3/3.5.1# composer install
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Package operations: 1 install, 0 updates, 0 removals
–prefer-source Forces installation from package sources when possible, including VCS information.
–prefer-dist Forces installation from package dist even for dev versions.
Puede ser que con esta ultima no te pida las credenciales.
IMPORTANTE: Igualmente para mi se debe a un problema de disponibilidad, ya que hasta hace un rato el gitlab estaba caído.
