「Gem ...已被刪除，它安裝在」Error。捆綁安裝不會安裝寶石。如何重新安裝寶石？

Question

我正試圖在XP上構建capybara-webkit。我遵循this instruction。我說：

8) Clone latest version of capybara-webkit from Github: 

$ git clone git://github.com/thoughtbot/capybara-webkit.git 

9) Bundle/Install capybara-webkit version: 

$ cd ruby193\capybara-webkit 
$ bundle install 

我是第一次這麼做的。它安裝了一些寶石。然後我按照指導步驟進行操作，但無法構建capybara-webkit。因此，再次開始，我刪除了手動安裝的所有寶石。現在我遵循所有相同的步驟，但bundle install不再工作。我說，所有的寶石都存在：

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>cd capybara-webkit 

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle install

Your bundle is complete! 
Use `bundle show [gemname]` to see where a bundled gem is installed. 

但現在我檢查這些寶石與bundle show，但它說，他們都被刪除：

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle show sinatra 
The gem sinatra has been deleted. It was installed at: 
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/sinatra-1.3.5 

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle show selenium-webdriver 
The gem selenium-webdriver has been deleted. It was installed at: 
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/selenium-webdriver-2.27.2 

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle show mini_magick 
The gem mini_magick has been deleted. It was installed at: 
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mini_magick-3.2.1 

怎麼可以這樣認爲bundle install說，他們是存在的，但bundle show說他們被刪除？所以bundle install不能再工作了。我如何再次使用bundle install來重新安裝這些寶石？

Answer 1

這解決了這個問題對我來說："gem install" and "bundle install" do not install gem dependencies after manual gem deletion. How to inform Rubygems that gems were deleted manually?

（刪除.gemspec文件已刪除了寶石）。
