Ruby拒絕承認我已經安裝了Rubygems ...爲什麼？

Question

C:\Users\wipe\Quora-Personal-Analytics>ruby hello.rb 
hello 
C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original 
_require': no such file to load -- bundler/setup (LoadError) 
     from C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in 
`require' 
     from hello.rb:4 

C:\Users\wipe\Quora-Personal-Analytics>ruby require 'date' 
ruby: No such file or directory -- require (LoadError) 

C:\Users\wipe\Quora-Personal-Analytics>ruby require 'rubygems' 
ruby: No such file or directory -- require (LoadError) 

C:\Users\wipe\Quora-Personal-Analytics>

我使用Ruby 1.8.7。此外，這工作之前（在同一臺計算機上）。

要求聲明全部做工作，當我從互動紅寶石嘗試的東西。因此，他們都安裝。但我需要命令行。

編輯：這裏是hello.rb的

puts "hello" 

require 'rubygems' 
require 'bundler/setup' 

require 'date' 
require 'watir' 
require 'optparse' 

的內容和一些新的錯誤：

C:\Users\wipe\Quora-Personal-Analytics>ruby require 'rubygems' 
ruby: No such file or directory -- require (LoadError) 

C:\Users\wipe\Quora-Personal-Analytics>ruby hello.rb

     from C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in 
`require' 
     from QuoraStats.rb:10 

不知何故，紅寶石包安裝並不能很好地工作：

C:\Users\wipe\Quora-Personal-Analytics>ruby bundle install 
ruby: No such file or directory -- bundle (LoadError) 

Answer 1

它看起來像你沒有安裝打包機。嘗試運行gem install bundler，然後重新運行ruby hello.rb。

此外，您輸入的最後兩個命令將不起作用。 ruby require 'date'將嘗試運行文件「require」並將其傳遞參數'date'，而不是執行require 'date'。要執行一行紅寶石，請使用-e標誌，如下所示：

ruby -e "require 'date'" 

Answer 2

您的堆棧跟蹤說

`gem_original _require': no such file to load -- bundler/setup (LoadError)

您確定bundler是否確實安裝？如果不是，請嘗試

gem install bundler 

並重試。

編輯：

隨着你收到新的錯誤，只是嘗試運行

`bundle install` 

然後再試一次。
