[BUG] How to setup at arm64 machine?

[LmDeng0]

I don't know how to setup retrowrite at arm64 machine, there have only command pip install -r requirements.txt at General setup in README.md file, it have no further suggest.
I try to run python setup.py, get the following hint, what should i do next.

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

I hope someone can give me answer, thank you very much.

It seems missing a comma at https://github.com/HexHive/retrowrite/blob/master/setup.py#L8.
