无法运行RSpec(未初始化的常量用户(NameError)

Question

尝试运行bundle exec rspec spec/models/user_spec.rb但未能执行(参见下面的错误).

user_spec.rb的内容:

require 'rails_helper'

describe User do
  pending "add some examples to (or delete) #{__FILE__}"
end

如果我删除最后3行,则完成0个示例和0个失败.但是,当最后3行存在时,会产生错误

/spec/models/user_spec.rb:4:in `<top (required)>': uninitialized constant User (NameError)
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/configuration.rb:1057:in `load'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/configuration.rb:1057:in `block in load_spec_files'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/configuration.rb:1057:in `each'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/configuration.rb:1057:in `load_spec_files'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/runner.rb:97:in `setup'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/runner.rb:85:in `run'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/runner.rb:70:in `run'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/lib/rspec/core/runner.rb:38:in `invoke'
    from /var/lib/gems/1.9.1/gems/rspec-core-3.0.3/exe/rspec:4:in `<top (required)>'
    from /usr/local/bin/rspec:23:in `load'
    from /usr/local/bin/rspec:23:in `<main>'

它似乎不知道用户是什么,并将其视为常量,而这实际上是一个模型.我已经在ruby沙箱中验证了我可以在数据库中创建新用户.有任何想法吗？

答:从.rspec中删除--warnings后(感谢kirti),目前的错误是关于水豚版本太低(需要2.2).安装最新版本(修改gemfile和bundle install)后,rspec似乎正在正确执行.感谢大家的意见.

Answer 1

我遇到了同样的问题,这是因为rspec/rails_helper.rb没有被调用.

我将它添加到.rspec文件中,所以我的文件看起来像这样

--color
--require spec_helper
--require rails_helper

这个并在spec/spec_helper.rb为我解决它时添加警告错误!

  config.warnings = false

Answer 2

从 .rspec 中删除 --warnings 后（谢谢 kirti），当前错误是关于水豚版本太低（需要 2.2）。安装最新版本（修改 gemfile 和捆绑安装）后，rspec 似乎可以正确执行。感谢大家的评论。
