Add an --intransitive option. #775
Conversation
If specified, only the explicitly provided requirements are resolved. Their transitive requirements are not. Since pex checks that all requirements are satisfied, this means that a complete transitive set must be provided explicitly in order to use this flag. This is useful if you have a lockfile from some other source and want pex to just apply it.

Your comment is true, so lgtm, but, as of today, Resolvable.get is still a strict subset. You can pip install an url pointing at a package as well as a local directory containing a setup.py.

Interesting. That isn't mentioned in that pip documentation though.

It sortof is. The archive url/path one is explicit. The local project path less so, since they only talk about the editable (prefix with -e) case. You can install a local project without -e and it just never updates after that if edited.
Each line of the requirements file indicates something to be installed, and like arguments to pip install, the following forms are supported:
[[--option]...]
<requirement specifier> [; markers] [[--option]...]
<archive url/path>
[-e] <local project path>
[-e] <vcs project url>
For details on requirement specifiers, see Requirement Specifiers.
