Embli-Cli Not work after Building

Iam working around Ember-Cli.I build a project and customize the "ember-cli-build.js" but finally it doesn't work. this is my work steps:
1) ember new myapp cd myapp ember server it works fine and i can see my project on "http://localhost:4200"
2) then run ember build --environment=production and get Built project successfully. Stored in "dist/". so it appear that my project built.
3) then i run this url on browser that direct to my dist directory project

localhost/~/myapp/dist/index.html

but nothing shows. i check the console and it seems that the "ember" is running, but nothing shows on the screen
