I'm trying to install this following this tutorial: https://ico.readthedocs.io/en/latest/install.html for Mac OS X, and I'm getting the following error:

    scrypt-1.2.0/libcperciva/crypto/crypto_aes.c:6:10: fatal error: 'openssl/aes.h' file not found
    #include <openssl/aes.h>

Thoughts?

Might it be this issue?

pyca/cryptography#2692

Which OSX version, and so on?

OSX Version: 10.13.3

I tried to execute the following but always stuck:

I am unable to help because I cannot repeat the problem.

However, I believe the error happens when it is installing scrypt package:

https://pypi.org/project/scrypt/

I suggest you try to install it by hand:

pip install scrypt

... and then resolve according to scrypt documentation and their support.

So, you need to do this:

env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install -r requirements.txt

Got this to work for me on High Sierra with MACOSX_DEPLOYMENT_TARGET=10.13 pip install pytype.

Try:
export CXX=clang
If it doesn't work try:
export CC=/usr/bin/clang
or
export CXX=/usr/bin/clang++

Using python 3.10, Mac Monterey 12.4. I needed to add these two flags:

export CPPFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"
