使用来自 rubyonrailstutorial 的 sample_app 的所有测试的错误
Errors on all tests using sample_app from rubyonrailstutorial
我大约 6 个月前完成了 Hartl 的 rubyonrailstutorial 的 sample_app，然后放下了。我今天去了 运行 它，现在我似乎在我的测试中收到与 "setup" 函数相关的错误。有 45 个错误 - 我会 post 下面是其中的 3 个：

虽然 Hartl 一直声明我们应该使用教程中的 gem 版本，但我确实将 ruby 版本从 2.1 更新到 2.2，并且我在 gem 中明确调用了它] 文件。
Ruby 版本： ruby 2.2.1p85（2015-02-26 修订版 49769）[x86_64-darwin13]
Rails 版本： Rails 4.2.0.beta4
系统： Mac OS X 版本 10.9.5
我最近将 mysql 安装到我的 Mac，但我没有在 sample_app 中使用它。 sample_app 按照教程中的建议使用 sqlite。我确保 mysql 的实例当时不是 运行ning。
声明"ArgumentError: wrong number of arguments (1 for 0)"在每个错误中都是一致的。此外，每个错误似乎都发生在 "setup" 方法中。
此应用在 6 个月前运行良好。关于我为什么会收到此错误的任何建议？
问题出在 'sample_app' 中使用的 Rails 版本。公平地说，Hartl 反复声明我们应该使用教程中显示的配置和 gem 版本。
我改了
gem 'rails', '4.2.0.beta4’
到
gem 'rails', '4.2.1’
那我运行bundle update
I 运行 bundle exec rake test 和 voila!，没有错误。
这解决了我原来post中的错误问题，但随后我收到以下警告：
DEPRECATION WARNING: The configuration option
config.serve_static_assets has been renamed to
config.serve_static_files to clarify its role (it merely enables
serving everything in the public folder and is unrelated to the
asset pipeline). The serve_static_assets alias will be removed in
Rails 5.0. Please migrate your configuration files accordingly.
(called from block in at
[.....]/sample_app/config/environments/test.rb:16)
这需要更新 /config/environments/test.rb 文件。改变了
config.serve_static_assets = true
到
config.serve_static_files = true
有关解决方案的详细信息，请参阅以下 link：
