Why do I get significantly different `package-lock.json` files when I run` npm install` on different systems

In the same git repository, if I remove node_modules and package-lock.json , I expect that running npm install should generate the same package-lock.json every time (send or receive several modules that can get updated by the publisher in the interim period.

What I find is that I get significantly different files depending on whether I run this on an OSX machine compared to a Linux machine.

Can this be expected? If so, what is the value of package-lock.json , since it will be invalid on one of these systems. If not, what could happen here?

Some dependencies are removed on some platforms. Perhaps some of them can be installed on the OSX machine, but not on Linux. So every time you run npm i , package-lock.json updated

For example, as some other users have pointed out, there is a fsevents package that has strict os requirements
