Rails未初始化的常数Bundler（NameError）

问题描述 投票：9回答：3

[运行rails s或rails c等任何rails命令时收到以下错误，这也阻止了我的heroku应用程序启动（相同的错误：]]

app/config/application.rb:7:in `<top (required)>': uninitialized constant Bundler (NameError)
from /Users/you/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:126:in `require'

错误消息中的第7行是：
Bundler.require(:default, Rails.env)

成功执行bundle exec rails s命令，但这对heroku应用没有帮助。我已经验证了which ruby，which rails和which bundler。我还尝试了启动新的rvm gemset并重新安装捆绑包。 heroku错误是相同的：
 /app/config/application.rb:7:in `<top (required)>': uninitialized constant Bundler (NameError)

正在运行bundle check不会返回任何问题。

一些类似的问题表明了这一点：

 bundle config --delete bin    # Turn off Bundler's stub generator
 rake rails:update:bin         # Use the new Rails 4 executables
 git add bin                   # Add bin/ to source control

但是我尝试过，没有任何变化。我在Rails 4

编辑：

我在另一个应用程序中工作并运行rails g model，然后弹出窗口：

Bundler is using a binstub that was created for a different gem.
This is deprecated, in future versions you may need to `bundle binstub rails` to work around a system/bundle conflict.

update2：如果我克隆存储库和bundle install，并尝试运行rails s或任何rake任务，则会复制bundler错误。但是，如果我随后执行gem install bundler和gem install rake，则新的回购协议将正常工作。卸载并重新安装我原始回购中的两个gem不会解决此问题。很高兴我找到了一个准修复程序，但仍然想深入了解这个问题。

update3：我认为我已将其范围缩小为与宝石有关的问题，但不确定如何进行。如果我使用默认的gemset运行用于触发错误的命令，则没有问题，只有当我切换到该项目的gemset时，我才会出错。在使用默认gemset测试命令之前，我没有运行bundle update。

update4：我已经在另一台机器上克隆了仓库，它复制了问题。因此，我想是时候该开始回头查看该问题之前的提交了，看看会发生什么？我的另一个想法是开始注释掉gem /删除依赖项，看看是否有帮助。我还有什么想看的吗？

删除所有宝石后，仍然出现带有uninitialized constant的警告。

这些来自bundler FAQ的命令起到了作用：

我刚刚在项目目录的根文件夹中使用rm -rf Gemfile.lock删除了锁，然后重新运行 bundle install，现在一切正常。
