Git dependency with sepcified branch gets overriden by dependency of other package.

This issue is simillar to #1779, but the solution stated there is not working for me.

I need to install specific version of a PyInstaller package, but PyInstaller is also a dependency of PyUpdater which is also required in my project and overrides other my specific PyInstaller version.

`$ python -m pipenv.help` output:

python -m pipenv.help

C:\Program Files (x86)\Python36-32\python.exe: No module named pipenv.help

I am aware this is not how this output should look like, but I can not make it work. Any help here? I’m on pipenv version 11.0.2.

Expected result

I need latest develop branch of PyInstaller installed and I don’t want PyUpdater to override this with the PyInstaller-3.3.1 version. As suggested in #1779 I placed PyUpdater above the PyInstaller in [packages] in Pipfile.

Actual result

Regardless whether the important part of Pipfile looks like this:

PyUpdater = "*"
PyInstaller = {git = "https://github.com/pyinstaller/pyinstaller", ref = "develop"}

or like this:

PyInstaller = {git = "https://github.com/pyinstaller/pyinstaller", ref = "develop"}
PyUpdater = "*"

the PyInstaller version in Pipfile.lock will be 3.3.1 and I end up with this version installed.

What is interesting is that if I uninstall PyInstaller with pipenv uninstall pyinstaller and then install it again with pipenv install https://github.com/pyinstaller/pyinstaller/archive/develop.zip I get the Successfully installed PyInstaller-3.4.dev0+b31794cf1 but in fact the 3.3.1 version in installed instead.

Steps to replicate

# Pipfile
[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[packages]
PyUpdater = "*"
PyInstaller = {git = "https://github.com/pyinstaller/pyinstaller", ref = "develop"}

pipenv install Check version: pipenv run pyinstaller --version

or

Create new clean environment pipenv install pyupdater pipenv uninstall pyinstaller pipenv install https://github.com/pyinstaller/pyinstaller/archive/develop.zip Check version: pipenv run pyinstaller --version

Ah, I think I know why this is happening!

Top-level dependency should always win, however, IMO. PyInstaller is specified in the Pipfile (i.e. top-level), so its version information shouldn’t be overridden by PyUpdater’s dependency specification. It could be sensible to raise an exception if it cannot reasonably resolve, but not silently override.
