Pip has the same kinds of issues with transitive dependencies, but way way way worse since it doesn't allow multiple versions. When you have lib A requiring C ("A -> C1") and "B -> C2", the version of C you get depends on which of A or B was installed first, because the second's requirements are flat-out ignored. Probably like 90% of the python projects I've looked at have requirement-conflicts because pip doesn't even warn you about this.
