All tests throwing TypeError: no implicit conversion of nil into String
更新 20180209：我创建了一个新的虚拟应用程序，其中包含初始 Rails 5.1.4 安装（包括 minitest 5.11.3）和测试，没有问题。将继续试验 gem 文件，看看我是否无法缩小世界范围内可能导致此问题的范围...
如果您有任何想法或指点，请告诉我！
我最近开始测试我的代码库的一个新部分，我发现了一个非常关键的问题。无论出于何种原因，每个测试现在都会抛出标题错误。查看跟踪，由于某种原因，我的测试中引用的 name/title 似乎导致了问题。不幸的是，我 知道 正在通过的 运行 测试（尽管承认在早期的 gem 版本中）会产生相同的结果，如下面的用户模型所示。
我已经尝试了所有我知道的方法，包括完全删除和重新安装 RVM、Rails 和 Ruby。我什至尝试过将 Minitest 版本控制到更早的版本，例如 10.5.3，但仍然没有成功。我花了一天的大部分时间试图解决这个问题；我束手无策，迫切需要帮助！虽然我已经学会了艰难的方法，但我现在需要明确地版本保护我所有的 gems ;)
提前致谢！如果您需要我添加更多内容，请告诉我 files/snippets。我会在我的日程安排允许的情况下尽力回复任何问题，希望能在 24 小时内回复。

当事情按预期工作时，通过恢复到较早的提交来解决这个问题，并通过 $ git checkout <branch> <file1> <file2> 方法引入所需的更新。
如果我不得不猜测，我认为我遇到的问题可能与我通过 RVM 对 2.5.0 的干预更新有关，这带来了比它值得的更多的麻烦（不是 Rails'这是错误，甚至是 RVM 的错误，因为 RVM 尚未正式支持 2.5.0。

当事情按预期工作时，通过恢复到较早的提交来解决这个问题，并通过 $ git checkout <branch> <file1> <file2> 方法引入所需的更新。
如果我不得不猜测，我认为我遇到的问题可能与我通过 RVM 对 2.5.0 的干预更新有关，这带来了比它值得的更多的麻烦（不是 Rails'这是错误，甚至是 RVM 的错误，因为 RVM 尚未正式支持 2.5.0。
