pipenv install --deploy --system is not working when using an editable package location

[pmantica1]

Issue description

After the latest release, the pipenv install --deploy --system command started to fail in the CI of a repository I am working on.

Expected result

I expected it to succeed without error since we haven't change the Pipfile or our CI setup anytime within the last few weeks and we've run CI multiple times since then. I verified that pinning the pipenv version to the previous version fixed the issue.

Actual result

We get a TypeError: expected string or bytes-like object error. For more info please look at:
https://travis-ci.org/github/kensho-technologies/graphql-compiler/builds/692595964

Steps to replicate

The Pipfile below is not our original CI Pipfile, but a minimal test case that still displays the issue. I've discovered that the issue appears when we try to install from an "editable package location". (The GraphQL Compiler is the name of the repository I am working on).

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[packages]
# The below is necessary to make a few pylint passes work properly, since pylint expects to be able
# to run "import graphql_compiler" in the environment in which it runs.
graphql-compiler = {editable = true, path = "."}

[requires]
python_version = "3.8"

This is the Travis CI setup file.

[techalchemy]

Thanks for reporting! FYI this failure due to using a function call (find_name()) to determine the name of your package (which, presumably, you know as the given file belongs to only one package)

It's nearly fixed as of #4302 but I just tested and the local editable dependency doesn't actually land in the Pipfile.lock with the current fix.
