🌍 Environment

• Your operating system and version: Windows 10 Pro (v1803)
• Your python version: 3.6.5
• How did you install python (e.g. apt or pyenv)? Did you use a virtualenv?: Through Windows installer and No.
• Your rust version: 1.27 (nightly)

💥 Reproducing

Please provide a minimal working example. This means both the rust code and the python.

Compiling the example on PyO3 main doc page using cargo +nightly build I get a lengthy list of errors complaining about "unresolved external symbols". I'm not sure what environment variable is rquired on windows for PyO3 to finid python36.lib. I've tried adding the path to "PATH" variable.

We'll need some more information to track this down:

• Which example did you use? The one with the main function or the one creating an extension module?
• Which is the exact rust version your using (The one you get from rustc --version)?
• Could you post the errors you got?
• What is the content of $PATH?
