所以我遇到了这个问题(创建 Rails 模型时出现语法错误),它有一个类似于我的错误。我从中推断出我的问题是使用 Ruby 1.8 而不是 1.9。我尝试按照其中一个答案中的说明卸载 gem 并更新 rubygems,但这并没有解决问题。我还尝试通过 rvm 将默认 ruby 设置为 1.9 - 它可以工作,但不能解决问题。
当我运行“gem env”时,我得到以下信息:
RubyGems Environment:
- RUBYGEMS VERSION: 1.8.23
- RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
- INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.8
- RUBY EXECUTABLE: /usr/bin/ruby1.8
- EXECUTABLE DIRECTORY: /usr/bin
- RUBYGEMS PLATFORMS:
- ruby
- x86_64-linux
- GEM PATHS:
- /usr/lib/ruby/gems/1.8
- /home/owner/.gem/ruby/1.8
- GEM CONFIGURATION:
- :update_sources => true
- :verbose => true
- :benchmark => false
- :backtrace => false
- :bulk_threshold => 1000
- REMOTE SOURCES:
- http://rubygems.org/
在 usr/bin 中,我有一个“ruby”,它是 usr/bin/ruby1.9.1 的符号链接。
基本上,我需要知道如何更改这里使用的红宝石(至少我认为这会解决我的问题)。
我的操作系统是 Linux Mint 12。Rails --version 返回“Rails 3.2.3”
我的完整错误如下(来自在项目目录中运行“rails s”):
=> Booting WEBrick
=> Rails 3.2.3 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
