Describe the bug
Can't install scrypt in node v12.
To Reproduce
Steps to reproduce the behavior:
When npm i or yarn, aelf-sdk requires scrypt.js, and scrypt.js takes scrypt as optional dependencies，which ignore error when installing. aelf-sdk take scrypt as an external package, without scrypt, it can't run.
Here is the problem, the preinstall step of scrypt failed in Node v12.
Expected behavior
Install scrypt successfully
Desktop (please complete the following information):
OS: macOS Mojave 10.14.5
Node v12.7.0
