Problem with `ps` not there when installing

I have a docker image which does not have ps installed (https://stackoverflow.com/a/26982502). When I run yarn add mongodb-memory-server I have such error:

I strongly believe this is because of mongodb-memory-server

node-gyp is not used by MMS, so this is not the place for questions about it (i could not help with it)

Excuse me, this is irrelevant to this package. My error I believe was because of my process manager.
