Can't running gin server after installed

[cpselvis]

I have installed luarockes as lua package manager and follow installation step as your document describes. Then I run commands as follows:

~ gin new demo
~ cd demo
~ gin start

After that, I get a error prompt like: ERROR: Could not start Gin app on port 7200 (is it running already?).

So, anything wrong?

[cpselvis]

Eh, My lua version is 5.2.4 and luajit is 2.0.4. I don't know wether it is compatiable.

@cpselvis you can run like

gin start --trace

for more information.

@cpselvis, based on the error message. It sounds like you actually might have something else bound to the port number 7200.

Perhaps:

• another server
• an earlier run of gin that you didn't kill correctly

Try lsof -i :7200 or ps aux | grep gin for more information.

Ahh, I did all my operation after restart my computer and it still cause that issue yesterday.

And I follow your tips just now, it still can't get to the point:

Sounds strange.

Hello, Gin is to be used with Lua 5.1 as per the specs. Can you see if this works for you?
