Install flask-bcrypt via pip: Unable to find vcvarsall.bat

I try to install flask-bcrypt via pip, but it raisis me this error:

error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat)

I am currently running Visual Studio 2015 RC with Python 3 on Windows 10.

Any ideas how to solve this error?

Edit: I tried to follow diffrent solutions and installed Visual Studio 2010 Express and am now stuck with teh following error (Installing via PIP in VS 2013):

'py-bcrypt' failed to install. Exit code: 1

Edit 2: I installed pycrypto via thsi Windows Installer: https://github.com/axper/python3-pycrypto-windows-installer which comes with bcrypt and suits my needs. But it would be nice to solve the original Problem.

Here is another option, you need to setup Wheel package before you can import bcrypt

pip install wheel

pip install bcrypt

 from flask_bcrypt import Bcrypt

Apparently the problem can be solved by installing py-bcrypt first. A win32 installer is available from the first comment to this reddit post:
