运行Extreme Startup Sinatra Web服务器时出错

Question

I'm trying to set up and run the Extreme Startup coding dojo on my Windows machine. 我正在尝试在Windows计算机上设置并运行Extreme Startup编码dojo。

When I try to access the front page on http://localhost:3000 , I get this error: 当我尝试访问http：// localhost：3000的首页时，出现此错误：

You're seeing this error because you have enabled the show_exceptions setting.

As far as I can tell, the offending line of code is on line 28, which seems to be this : 据我所知，令人反感的代码行在第28行，这似乎是这样的：

haml :leaderboard, :locals => {
    :leaderboard => LeaderBoard.new(scoreboard, players, game_state),
    :players => players  }

Unfortunately, my knowledge of Ruby is almost non-existent, so nothing there looks untoward to me. 不幸的是，我对Ruby的了解几乎不存在，所以对我来说没有什么不好的。

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. 当我启动Web服务器时，它会产生此输出，包括一个警告，表明我（到目前为止没有成功）已尝试摆脱该警告。 I don't know if it's related: 我不知道是否相关：

What's wrong, and what can I do to fix the issue? 有什么问题，我该怎么解决？

I know almost nothing about Ruby, so it's probably a stupid beginner's mistake. 我对Ruby几乎一无所知，所以这可能是一个愚蠢的初学者的错误。

Answer 1

Your problem is that the application was developed a long time ago an nobody took the time to upgrade. 您的问题是该应用程序是很久以前开发的，没有人花时间升级。

For example you should run it with ruby 1.9.3 which is end of live. 例如，您应该使用已结束的ruby 1.9.3运行它。 But using a newer ruby version would probably work. 但是使用更新的红宝石版本可能会起作用。 (at least ruby-2.1.6 works for me) （至少ruby-2.1.6对我有用）

But what definitely not works is to run this project with sinatra v1.4.6. 但是，绝对不可行的是使用sinatra v1.4.6运行该项目。 As you can see in the source code this project was build with v1.2.6 . 正如您在源代码中看到的那样，该项目是使用v1.2.6构建的。 Probably you have installed a newer version of sinatra for a other project. 可能您已为其他项目安装了较新版本的sinatra。 So I would recommend that you install the gems in your project folder with: 因此，我建议您使用以下命令在项目文件夹中安装gems：

bundle install --binstubs --path vendor 捆绑安装--binstubs --path供应商

If installed this way you can have multiple projects with the same dependency with out a problem. 如果以这种方式安装，则可以有多个具有相同依赖项的项目，而不会出现问题。 But now you need to prefix you commands with bundle exec for example bundle exec ruby web_server.rb . 但是现在您需要在命令之前加上bundle exec前缀，例如bundle exec ruby web_server.rb 。

Or if you are using rvm there is this thing called gemsets which does something similar. 或者，如果您使用的是rvm ，那么有个叫做gemsets的东西可以做类似的事情。
