    - You can only install one version of a package, so only one of these can be installed: netresearch/jsonmapper[v1.0.0, ..., v1.6.0, v2.0.0, v2.1.0, v3.0.0, v3.1.0, v3.1.1, v4.0.0, ..., v4.5.0, v5.0.0].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
