--EXPECT-OUTPUT--
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
- Required package "newly-required/pkg" is not present in the lock file.
This usually happens when composer files are incorrectly merged or the composer.json file is manually edited.
Read more about correctly resolving merge conflicts https://getcomposer.org/doc/articles/resolving-merge-conflicts.md
and prefer using the "require" command over editing the composer.json file directly https://getcomposer.org/doc/03-cli.md#require-r
