新的Rails應用程序和捆綁安裝執行錯誤

Question

我正在創建新的應用程序，其作爲最後一步，運行bundle install命令，該命令將失敗：

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)

from /Users/khataev/.rbenv/versions/2.2.2/bin/rails:23:in `<main>' 

它爲什麼會失敗？我安裝了捆綁，但它給了我一個錯誤，如果我試圖從那裏我跑了rails new命令的目錄中運行它：

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

但該項目目錄內正常工作。也許這是原因？

Answer 1

我不確定我是否正確理解您的問題。所以你在一個目錄中，你運行例如「rails new test」。這會創建一個名爲「test」的新項目文件夾。你只能在「test」文件夾內運行你的bundle命令，因爲這是一個包含gemfile告訴打包者安裝什麼gem的文件夾。
