Hi,
I tried to install abad but I get:

/usr/local/bin/abao -> /usr/local/lib/node_modules/abao/bin/abao
/usr/local/lib
└─┬ abao@0.3.1
├── UNMET PEER DEPENDENCY chai@>= 2.0.0 < 3
└─┬ request@2.65.0
└── node-uuid@1.4.4

npm WARN EPEERINVALID chai2-json-schema@1.2.0 requires a peer of chai@>= 2.0.0 < 3 but none was installed.

I used sudo npm install -g abao on a Mac,
thanks for any help
