Can't pip install bitcoinlib on Windows 10 with Python 3.7 about bitcoinlib

[mccwdev]

What could help is installing scrypt first with pip install scrypt and then bitcoinlib.

Also the library isn't tested yet with python 3.7, so for now it's better to use python 3.6.

Any succes yet? The latest bitcoinlib version 4.2 is tested with Python 3.7 so this shouldn't cause any problems. The scrypt package also requires the development version of Python, I'm not sure if this version is installed by default in your Windows / Visual Studio environment.

No success, I need a way to point it to the correct location of openssl/aes.h I think. Is that what the issue seems to be?

Thank you

It seems there are no binary wheels for the scrypt package for Python 3.7, see https://pypi.org/project/scrypt/. So it tries to compile them and then fails. I'm not sure why it fails and how to solve it. Another thing you could try is to install the openSSL library.

In the new version 0.4.4 support for pyscrypt is added, if installation of scrypt fails. Pyscrypt is slow but this is not a problem if you're not using BIP38 password protected private keys.

Just install bitcoinlib and if you run into scrypt errors try 'pip install pyscrypt'

I had the same issue with macos.

I solved it with setting the export flags one time. Then I was able to pip install scrypt and everything worked thereafter.
