Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires biigle/auth-lslogin dev-master -> satisfiable by biigle/auth-lslogin[dev-master]. - biigle/auth-lslogin dev-master requires socialiteproviders/lifesciencelogin ^6.0 -> found socialiteproviders/lifesciencelogin[6.0.0] but the package is fixed to 5.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
