Hi @darrenleeweber,

If you do pip list, that should give you pip-tools' version. I'm ready to bet it's <2.0.0, and you just have to update to 2.0.1 for pip 10 support 😃 .

I'll go ahead and close the issue, comment back if upgrading to latest pip-tools (currently 2.0.2) did not solve the issue.

I'm still having the issue with 2.0.2 on OSX.

> pip --version
pip 10.0.1 from /Library/Python/2.7/site-packages/pip (python 2.7)
> pip list | grep pip-tools
pip-tools     2.0.2

Opening piptools/utils.py shows `from pip.req import InstallRequirement' instead of the correct version that appears on GitHub.
