问题
I wrote a cowboy project that I start on localhost with gmake run.
When I make run on a fresh installation, this error happens:

and the tunnel_sup.erl that it calls with start_link:

I'm able to copy a folder on my machine and it works. When I upload this to github and download it, make run fails.

What configuration could be causing this?
EDIT:
Juanjo Martin's answer works, in my cloned folder.
In my original folder, it does not, and removing the 100 argument gets me the below.
Why is this not working in 1 specific folder? What kind of environment fix do I have to check/make to prevent this? It seems like ~/tunnel is running a different version of cowboy?

Aha. I did the comment's instruction from @lastcanal and it works. Thanks.
回答1:
First thing I see is you don't have an .app file
You can check a similar problem in why-is-my-cowboy-server-not-running
flag
In tunnel_app.erl module you're calling cowboy:start_clear with an arity of 4 but the arity for this function is 3. That's why the undef error:
exited: {bad_return, {{tunnel_app,start,[normal,[]]}, {'EXIT', {undef, [{cowboy,start_clear, [my_http_listener,100, [{port,8080}],
... You should remove the parameter "100"
This must have been from an earlier version of Cowboy, possibly
