【问题描述】：

我刚刚在 OS X Mountain Lion 上安装了 RVM、Ruby 2.0 和 Rails 3.2.15。每次我开始一个新的 Rails 项目时，我都会得到以下信息：

➜  ~  rails new new_proj
  create
  create  README.rdoc
  create  Rakefile
  create  config.ru
  create  .gitignore
  create  Gemfile
  create  app
  create  app/assets/images/rails.png
  create  app/assets/javascripts/application.js
  create  app/assets/stylesheets/application.css
  create  app/controllers/application_controller.rb
  create  app/helpers/application_helper.rb
  create  app/mailers
  create  app/models
  create  app/views/layouts/application.html.erb
  create  app/mailers/.gitkeep
  create  app/models/.gitkeep
  create  config
  create  config/routes.rb
  create  config/application.rb
  create  config/environment.rb
  create  config/environments
  create  config/environments/development.rb
  create  config/environments/production.rb
  create  config/environments/test.rb
  create  config/initializers
  create  config/initializers/backtrace_silencers.rb
  create  config/initializers/inflections.rb
  create  config/initializers/mime_types.rb
  create  config/initializers/secret_token.rb
  create  config/initializers/session_store.rb
  create  config/initializers/wrap_parameters.rb
  create  config/locales
  create  config/locales/en.yml
  create  config/boot.rb
  create  config/database.yml
  create  db
  create  db/seeds.rb
  create  doc
  create  doc/README_FOR_APP
  create  lib
  create  lib/tasks
  create  lib/tasks/.gitkeep
  create  lib/assets
  create  lib/assets/.gitkeep
  create  log
  create  log/.gitkeep
  create  public
  create  public/404.html
  create  public/422.html
  create  public/500.html
  create  public/favicon.ico
  create  public/index.html

  create  script
  create  script/rails
  create  test/fixtures
  create  test/fixtures/.gitkeep
  create  test/functional
  create  test/functional/.gitkeep
  create  test/integration
  create  test/integration/.gitkeep
  create  test/unit
  create  test/unit/.gitkeep
  create  test/performance/browsing_test.rb
  create  test/test_helper.rb
  create  tmp/cache
  create  tmp/cache/assets
  create  vendor/assets/javascripts
  create  vendor/assets/javascripts/.gitkeep
  create  vendor/assets/stylesheets
  create  vendor/assets/stylesheets/.gitkeep
  create  vendor/plugins
  create  vendor/plugins/.gitkeep
     run  bundle install
/Gemfile not found

这是which rails和which gem和which bundle的输出

➜  ~  which rails
/Users/jeff/.rvm/gems/ruby-2.0.0-p247/bin/rails
➜  ~  which gem
gem () {
typeset result
(
    typeset rvmrc
    rvm_rvmrc_files=("/etc/rvmrc" "$HOME/.rvmrc")
    if [[ -n "${rvm_prefix:-}" ]] && ! [[ "$HOME/.rvmrc" -ef "${rvm_prefix}/.rvmrc" ]]
    then
        rvm_rvmrc_files+=("${rvm_prefix}/.rvmrc")
    fi
    for rvmrc in "${rvm_rvmrc_files[@]}"
    do
        [[ -s "${rvmrc}" ]] && source "${rvmrc}" || true
    done
    unset rvm_rvmrc_files
    command gem "$@"
) || result=$?
hash -r
return ${result:-0}
}

➜  ~  which bundle
/Users/jeff/.rvm/gems/ruby-2.0.0-p247@global/bin/bundle

有人知道为什么吗？

【问题讨论】：

尝试手动运行捆绑安装。会发生什么？
您的捆绑包已完成！使用 bundle show [gemname] 查看捆绑 gem 的安装位置...奇怪的是，如果我手动执行它，它会起作用，如果这是我必须一直做的事情，那就不好了。
每次更新 gemfile 时都必须手动进行捆绑安装（rails 只会在您创建新项目后自动安装 :)）。
好吧，我把范围缩小了一点。我使用 rbenv 而不是 RVM，一切都按计划进行，没有问题。问题在于 rvm，但我不太确定它是什么。
我也看到“/Gemfile not found”，但仅在我使用 ruby 1.9.3-p448 时。我使用 RVM，当我切换到 1.9.3-p392 时，一切正常。

【解决方案1】：

我给我的'bundle exec' 命令起了别名，我得到了和你一样的错误。我删除了别名... BOOM！有效！
