Pip hangs when using "-d . -e " args within a python package

[jamesls]

I was trying to download all the dependencies of a local python package and noticed that running pip install -d . -e <path to python package dir> from any subdir of the package will hang and python will consume 100% CPU. Repro:

# Start from directory that contains the setup.py
# Running "pip install -d . -e ." will work from this directory.
mkdir foo
cd foo
pip install -d . -e ../  # This command will hang.
pip install -d . -e $(dirname $(pwd)) # Absolute path will also hang.

Other data points:

pip install -d /outside/of/package -e ../ works.
Running pip install -d . -e <packagedir> outside of <packagedir> or at the top level of <packagedir> works.

Closing this. In the master branch we no longer have the -d flag to pip install, and it's replacement pip download does not have the -e flag. If you're able to reproduce this otherwise with the new command please reopen this issue or open a new issue.
