问题描述
在我将 rails 从 4.1 和 ruby 从 2.0 升级到 2.1 之后，我在尝试启动 rails 时遇到了几个负载问题.我的许多宝石都抛出这样的错误:
After I just upgrade rails from 4.1 and ruby from 2.0 to 2.1 I'm getting several load issues when I try to start rails. Many of my gems are throwing errors like this:

我的 gem 文件如下所示:
My gem file looks like this:
source 'https://rubygems.org'
# Rake and rails
gem 'rake', '10.3.2'
gem 'rails', '4.1.6'
gem 'protected_attributes'
gem 'rails-observers'
gem 'actionpack-page_caching'
gem 'actionpack-action_caching'
gem 'activerecord-deprecated_finders'

gem 'dalli', '2.7.2'
gem 'hstore_accessor', '~> 0.6.0'

gem 'rubyXL', '~> 3.2.3'

gem 'bcrypt-ruby', '~> 3.1.2', require: 'bcrypt'
gem 'redis-objects', '~> 1.0.0'
gem 'leaderboard', '~> 3.7.0'
现在，如果我将 omniauth-facebook 注释掉，那么我只会得到 bcrupt 的以下内容:
Now if I then comment out omniauth-facebook then i just get the following for bcrupt instead:

它就这样继续下去.为什么我的一些宝石会突然导致这种情况?
And it just continues like that. Why are some of my gems suddenly causing this?
推荐答案
您的本地 ruby 安装肯定有问题.
There must be some problem in your local ruby installation.
如果您使用的是 rvm gemset，则在您的 gemset 上运行 rvm pristine.如果您不使用 gemset，请运行 gem pristine --all
If you are using rvm gemset then run rvm pristine on your gemset.If you are not using gemset then run gem pristine --all
