What I Did

pip install -U bigchaindb-driver

The problem is that PyNaCl (cryptographic software) requires some operating system dependencies and I'm not sure how you get those dependencies installed on Windows, or if that's even possible.

You will save yourself a lot of trouble by using Linux or macOS instead of Windows. Windows has a "Windows Subsystem for Linux" (WSL) available on the Windows Store (under "Ubuntu"). Maybe try using that. If that doesn't work, then maybe try a virtual machine with Ubuntu inside it.

[ankitgaur]

made it to work using an ubuntu emulator on windows.

Great!
