pip install as source with dependencies separate

I'm trying to release a demo repository (where people can directly run python scripts to demonstrate some experiment). I also need to include dependencies (numpy, etc). I'd like to use pip to make it easy.

I've already made a setup.py file listing all the dependencies. I'd now like to install my repo's code the the current directory, and all the dependencies to the default path (eg. ./venv/lib/python2.7, venv/src/, etc).

Now, if I just run pip install -e git+http://github.com/petered/my_repo.git#egg=my_repo

Everything works, except the code in my_repo gets saved in the /venv/src (whereas I want it in the root directory).

I can also run pip install -e git+http://github.com/petered/my_repo.git#egg=my_repo --target=.

Which installs everything in the root (current) directory. But then all dependencies also end up in this directory.

How can I pip install just the source code of a package in the current directory, but all dependencies in the default directory for dependencies?

My projects usually have a setup.py file that defines all dependencies. To install the project in a virtualenv I then first clone the repository and then simply install the cloned repository:

git clone http://github.com/petered/my_repo.git .
pip install -e .

This will install my_repo where it is, but install all dependencies into lib/python2.7/site-packages/.

You will notice that this layout makes it possible to later publish the my_repo to PyPI, or install it as a dependency into lib/... if you wish to do so as the library itself has no idea about how it was installed.

Whenever I have several "private dependencies" (closed source, only available on our git server), I write installation instructions like

git clone http://github.com/petered/my_repo.git
git clone http://github.com/petered/my_repo_dependency_1.git
git clone http://github.com/petered/my_repo_dependency_2.git
pip install -e my_repo_dependency_1
pip install -e my_repo_dependency_2
pip install -e my_repo

in the readme file. This will install all private dependencies in place, but install all public PyPI dependencies in lib/python2.7/site-packages/.
