I go the same error, but was able to fix after running the followimg commands:

/////
brew install pkg-config libffi
sudo bash
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
export PKG_CONFIG_PATH=/usr/local/Cellar/libffi/3.0.13/lib/pkgconfig/
pip install bcrypt
///////

//// Now run
pip install -r requirements.txt

///////
Seems like Vik added the following to the contained documentation to fix this error as well
///////
