Rails 生成控制器给了我加载错误

Question

我尝试生成一个控制器，但它给了我这个错误。我无法在我的文件中找到导致此错误的原因，因此非常感谢您的帮助。如果有帮助的话，我正在运行 Ruby '2.0.0' 和 rails '4.2.0.beta2'。请帮忙！谢谢

我不明白为什么这篇文章被标记为重复。我的问题与其他问题无关。另外，我在问如何修复它，据我阅读，我什至没有看到该错误的修复。请帮忙！

问题是 Rails 4.2.0.beta 依赖于 pty gem 并且无法找到它：

`require': cannot load such file -- pty

原因是pty gem 在 Windows 上不可用。希望在 Rails 4.2 发布之前得到解决。目前，您可以通过从 Gemfile 中删除 web-console gem 来解决此问题：

# Gemfile
# gem 'web-console'

删除该 gem 后运行 bundle install。

要解决no source of timezone data could be found (TZinfo::DataSourceNotFound) 的问题，请将以下行添加到您的Gemfile：

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]

然后再试一次：

bundle install
bundle exec rails generate controller StaticPages home help
