pip install doesn't work when requirements.txt has an editable dependency from git

Question

I have the following Pipfile with a single dependency from git:

[packages]
requests = {editable = true, git = "https://github.com/requests/requests.git",ref = "v2.20.1"}

Then I run:

pipenv install
pipenv run pip freeze >requirements.txt

Which generates this requirements.txt:

certifi==2020.6.20
chardet==3.0.4
idna==2.7
-e git+https://github.com/requests/requests.git@6cfbe1aedd56f8c2f9ff8b968efe65b22669795b#egg=requests
urllib3==1.24.3

Now this works fine: pipenv run pip install -r requirements.txt

But this doesn't: pipenv run pip install -r requirements.txt --target dist

Error:

If I remove editable = true, it will work, but I need it to be editable so transitive dependencies are added to the Pipfile.lock as described here.

So my question is: why the --target flag doesn't work when requirements.txt has an editable dependency from git?

I'm using python 3.8.2 and pip 20.2.2.
