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.

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

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
