You're seeing this error because you have enabled the show_exceptions setting.
据我所知，有问题的代码行在第 28 行，这似乎是这个:
As far as I can tell, the offending line of code is on line 28, which seems to be this:
haml :leaderboard, :locals => {
:leaderboard => LeaderBoard.new(scoreboard, players, game_state),
:players => players }
不幸的是，我对 Ruby 的了解几乎不存在，所以没有什么对我不利.
Unfortunately, my knowledge of Ruby is almost non-existent, so nothing there looks untoward to me.
当我启动 Web 服务器时，它会产生这个输出，包括一个警告，我(到目前为止没有成功)试图摆脱它.不知道有没有关系:
When I start the web server, it produces this output, including a single warning, that I (so far unsuccessfully) have tried to get rid of. I don't know if it's related:

出了什么问题，我该怎么做才能解决这个问题?
What's wrong, and what can I do to fix the issue?
我对 Ruby 几乎一无所知，所以这可能是一个愚蠢的初学者错误.
I know almost nothing about Ruby, so it's probably a stupid beginner's mistake.
推荐答案
您的问题是应用程序是很久以前开发的，没有人花时间升级.
Your problem is that the application was developed a long time ago an nobody took the time to upgrade.
例如，您应该使用 ruby 1.9.3 运行它，它已终止运行.但是使用较新的 ruby 版本可能会奏效.(至少 ruby-2.1.6 对我有用)
For example you should run it with ruby 1.9.3 which is end of live. But using a newer ruby version would probably work. (at least ruby-2.1.6 works for me)
但绝对行不通的是用 sinatra v1.4.6 运行这个项目.正如你在源代码中看到的，这个项目是用 v1.2.6<构建的/a>.可能您已经为其他项目安装了较新版本的 sinatra.所以我建议你在你的项目文件夹中安装 gems:
But what definitely not works is to run this project with sinatra v1.4.6. As you can see in the source code this project was build with v1.2.6. Probably you have installed a newer version of sinatra for a other project. So I would recommend that you install the gems in your project folder with:
捆绑安装 --binstubs --path vendor
bundle install --binstubs --path vendor
如果以这种方式安装，您可以拥有多个具有相同依赖项的项目而不会出现问题.但是现在您需要在命令前加上 bundle exec 前缀，例如 bundle exec ruby web_server.rb.
If installed this way you can have multiple projects with the same dependency with out a problem. But now you need to prefix you commands with bundle exec for example bundle exec ruby web_server.rb.
或者，如果您使用的是 rvm，则有一个名为 gemsets 的东西，它执行类似的操作.
Or if you are using rvm there is this thing called gemsets which does something similar.
