+Your requirements could not be resolved to an installable set of packages.

+  Problem 1
+    - Root composer.json requires symlinked/path-pkg * -> satisfiable by symlinked/path-pkg[2.0.0].
+    - symlinked/path-pkg 2.0.0 requires symlinked/transitive 2.* -> found symlinked/transitive[2.0.3] but the package is fixed to 1.0.0 (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.
