#17 1.879   Problem 1
#17 1.879     - Root composer.json requires sweetrdf/easyrdf 1.13.* -> satisfiable by sweetrdf/easyrdf[1.13.0, 1.13.1].
#17 1.879     - sweetrdf/easyrdf[1.13.0, ..., 1.13.1] require php ^8.0 -> your php version (7.4.3) does not satisfy that requirement.
#17 1.879 
#17 1.879 Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.
