新的Rails应用程序和捆绑安装执行错误

Question

我正在创建新的应用程序，其作为最后一步，运行bundle install命令，该命令将失败：

run bundle install /Users/khataev/.rbenv/versions/2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:128:in `require': cannot load such file -- bundler (LoadError)

它为什么会失败？我安装了捆绑，但它给了我一个错误，如果我试图从那里我跑了rails new命令的目录中运行它：

khataev@~/Documents/development/rails$ bundle install 
Could not locate Gemfile or .bundle/ directory 

但该项目目录内正常工作。也许这是原因？

Answer 1

我不确定我是否正确理解您的问题。所以你在一个目录中，你运行例如“rails new test”。这会创建一个名为“test”的新项目文件夹。你只能在“test”文件夹内运行你的bundle命令，因为这是一个包含gemfile告诉打包者安装什么gem的文件夹。
