rspec：“没有要加载的文件-- rspec/mocks”

Question

我正尝试在一些非常简单的Ruby上运行一个测试。我在我的linux机器上安装了ruby和rails。我还安装了rspec。我的宝石清单是：

LOCAL GEMS

actionmailer (3.2.8)

thor (0.16.0)
tilt (1.3.3)
treetop (1.4.10)
tzinfo (0.3.33)

但是当我跑的时候

 rspec my_test_file.rb

我得到以下错误：

/usr/lib/ruby/vendor_ruby/rspec/core/mocking/with_rspec.rb:1:in `require': no such file to load -- rspec/mocks (LoadError)
from /usr/lib/ruby/vendor_ruby/rspec/core/mocking/with_rspec.rb:1
from /usr/lib/ruby/vendor_ruby/rspec/core/configuration.rb:116:in `require'
from /usr/lib/ruby/vendor_ruby/rspec/core/configuration.rb:116:in `mock_framework'
from /usr/lib/ruby/vendor_ruby/rspec/core/configuration.rb:376:in `configure_mock_framework'
from /usr/lib/ruby/vendor_ruby/rspec/core/command_line.rb:19:in `run'
from /usr/lib/ruby/vendor_ruby/rspec/core/runner.rb:55:in `run_in_process'
from /usr/lib/ruby/vendor_ruby/rspec/core/runner.rb:46:in `run'
from /usr/lib/ruby/vendor_ruby/rspec/core/runner.rb:10:in `autorun'
from /usr/bin/rspec:4

这似乎是rspec/mocks特有的(不像SE上发布的其他“没有这样的文件可以加载”的ruby错误)。那么我错过了什么呢？

Answer 1

这根本不是rspec的问题。我的机器就是不知道去哪里找gem文件。我必须按如下方式更新我的.bashrc文件：

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "/home/jason/.rvm/scripts/rvm" ]] && . "/home/jason/.rvm/scripts/rvm" # Load RVM function

现在一切都正常了。
