【问题描述】：

我的 Gemfile 中有以下行：

gem 'authlogic', :git => "git://github.com/binarylogic/authlogic.git"

当我推送到 heroku 时，我收到以下错误：

当然，该应用程序不起作用。

对可能导致这种情况的任何想法？因为乍一看，它可能来自 AuthLogic (https://github.com/binarylogic/authlogic) 代码。

更新：

好的。最奇怪的事情刚刚发生。它自己开始的。看来我只需要给它一些时间，它现在正在工作......

这里留给以后遇到同样问题的人。

但是，最好知道导致 AuthLogic 错误的原因。

【问题讨论】：

你能添加完整的错误吗？还是只有这三行输出？
看起来 UTF-8 TLDs and IDNs 在人们能够解决他们的字符编码问题之前都会成为麻烦。
tadman，请参阅sawa 答案的评论——我已经在所有文件中明确声明了 UTF-8。
Mab879，你的愿望实现了。请参阅上面的更新日志。
这是reported as an issue。

【解决方案1】：

看来只是替换

gem 'authlogic', :git => "git://github.com/binarylogic/authlogic.git"

与

gem 'authlogic'

然后

rm Gemfile.lock
bundle install
git push heroku master

导致应用启动。

【讨论】：

无需删除整个锁文件，更新单个gem运行bundle install --source authlogic
