我创建了一个新的 Rails API 应用程序。我正在尝试使用 postgres db 命令为应用程序创建数据库表
rake db:create:all
我收到此错误:
AM@~/Documents/RailsWS/iosprototypevendors >rake db:create:all --trace
rake aborted!
Valid types are [:development, :runtime], not nil
/usr/local/lib/ruby/site_ruby/1.8/rubygems/dependency.rb:52:in `initialize'

..............
经过一番谷歌搜索，我发现这可能与选择的 ruby 版本错误有关。
(我最近将我的操作系统升级到 Mountain Lion，并且必须将我的 Rails 和 Ruby 版本升级到最新版本。为了让 Rails 正常运行，我经历了 8 个小时的痛苦。Rails 现在可以在我的系统上运行，但这是一个差异，刚刚弹出)。
另外
我还注意到，对于我系统上的不同rails应用程序，当我使用rails -v检查它们的版本时，rails的版本有时会显示为3.2.1，有时会显示为3.2.8，有时我会收到上述错误消息。
怎么会发生这种事？ 这是我通过运行此命令得到的结果:

这些是我系统上的路径
最佳答案
这是一个已知路径问题。检查您的路径是否包含有效的 gem 路径。您是否也安装了没有 rvm 的 ruby？看看:Path's issue with bundler, to change or not to change?
关于ruby-on-rails - 使用rails命令 "rake db:create:all"时出错 - 我认为它与Ruby的版本冲突有关，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12304414/
