很多：‘`require'：无法加载这样的文件-- "gem_name“(LoadError)，在ruby/rails升级之后

Question

在我将rails从4.1升级到ruby从2.0升级到2.1之后，我在尝试启动rails时遇到了一些负载问题。我的许多宝石都犯了这样的错误：

我的gem文件如下所示：

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'

现在，如果我注释掉了omniauth-facebook，那么我只得到bcrupt的以下内容：

就这样继续下去。为什么我的一些宝石突然引起了这一切？

Answer 1

您的本地红宝石安装一定有问题。

如果您使用的是rvm，那么在您的gemset上运行rvm pristine。如果您没有使用gemset，那么运行gem pristine --all

Answer 2

对我来说，感觉就像在全球范围内安装了一些宝石，没有邦德勒，也没有将宝石添加到您的Gemfile中。如果没有您的Gemfile.lock，很难判断，但例如，jwt Gem不在您的Gemfile中。

我会尝试将丢失的宝石添加到您的Gemfile中，再次运行bundle install。

Answer 3

您是否尝试过在应用程序中重新安装带有bundler的gems？

bundle install --path vendor/bundle

另外:如果这没有帮助，我将尝试删除rvm中的rvm并再次尝试bundle / rails c。
