After installing sublime 2/3, use this https://packagecontrol.io/installation
Then use Administrator to launch sublime. From preference -> package control -> Settings - User, add a block
"channels":
[
"https://packagecontrol.io/channel_v3.json",
"https://web.archive.org/web/20150905194312/https://packagecontrol.io/channel_v3.json"
],
I find that it is a good idea to use SublimeREPL. So I spent quite a few hours to search a solution for "There are no packages available for installation" issue. This solution was mentioned at here. I guess there could be different reasons, and different solutions. Above one worked this time.
