Not recognizing virtaulenv created with pyenv.

[iml1111]

Context

If .python-version does not exist in the current path, the virtual environment of pyenv is not recognized.

Expected Behavior

> zappa update dev
Calling update for stage dev..
Downloading and installing dependencies..
...

Actual Behavior

# .python-version is not in that path, but pyenv works correctly.
> pwd
/Users/username/Documents/GitHub/myenv/myproject
> pyenv versions
* my-env (set by /Users/username/Documents/GitHub/my-env/.python-version)
...

> zappa update dev
Calling update for stage dev..
Error: Zappa requires an active virtual environment!

Possible Fix

In addition to detecting the .python-version file in the current path, you can check the current virtual environment by using the pyenv version command.
