[maiocchim]

running from command line on my windows 10 PC the command pip3 install web3-gear

after a while I get this error:

Looks like there's no OpenSSL toolkit.

Have you done these two steps?

1. Install Visual C++ Build Tools.
2. Install scrypt-py use the precompiled wheels.

Or you can manually install this tool -- OpenSSL.

I got issue quite the same when I try to install it on Centos 7

"/usr/bin/python3.6 -u -c "import setuptools, tokenize;file='/tmp/pip-install-h49sy8rb/scrypt/setup.py';f=getattr(tokenize, 'open', open)(file) ;code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-record-tdj5xes_/install-record.txt --single-ver sion-externally-managed --compile" failed with error code 1 in /tmp/pip-install-h49sy8rb/scrypt/

@sangduongvan Try install scrypt-py use the precompiled wheels.
