当我运行Rails 4.1.2服务器时，我没有错误。
但是，如果我运行'rails c'，我会收到以下错误：
Could not find activesupport-4.1.2 in any of the sources
Run `bundle install` to install missing gems.
奇怪的是，activesupport-4.1.2已经安装并在Gemfile.lock中指定。我尝试过'捆绑更新'以及删除Gemfile.lock并运行'bundle install'。我也尝试在我的Rails gemfile中指定特定版本的ActiveSupport，但这已经无处可去了。
我真的很想使用最新的Rails，但是我无法使用控制台似乎非常糟糕。
FIY：我在Linux中使用Ruby 2.1.2p95和RVM。
编辑：我卸载了所有activesupport gems并重新安装了4.1.2。以下是'gem list activesupport所说'：
*** LOCAL GEMS ***
activesupport (4.1.2)
同样的问题。
EDIT2：这是我的Gemfile.lock：

EDIT3：这是我的.irbrc文件：
# This loads some niceties for irb, courtesy of rvm.
# It also loads your custom ~/.irbrc if it exists.
# If you want to customize the irbrc for ONLY this version of
# ruby then edit this file. It will only be deleted if you do
# an "rvm install" over this ruby version.
if ENV["rvm_path"].nil?
require File.join(ENV["HOME"], "irbrc")
else
require File.join(ENV["rvm_path"], "scripts", "irbrc")
end
答案 0 :(得分：16)
Spring还在运行并且干扰。在shell中运行以下操作可以解决问题：
spring stop
现在Rails控制台可以正常工作。
