Ruby 拒绝承认我已经安装了 Rubygems……为什么？

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>

我正在使用 Ruby 1.8.7。此外，这以前有效(在同一台计算机上)。

当我尝试使用交互式 ruby​​ 进行操作时，require 语句都做 工作。所以它们都已安装。但我需要命令行。

编辑:这里是Hello.rb的内容

puts "hello"

require 'rubygems'
require 'bundler/setup'

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

还有一些新的错误:

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
hello
←[31mCould not find OptionParser-0.5.1 in any of the sources←[0m
←[33mRun `bundle install` to install missing gems.←[0m

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

C:\Users\wipe\Quora-Personal-Analytics>ruby -e "require 'date'"

C:\Users\wipe\Quora-Personal-Analytics>ruby -e "require 'rubygems'"

C:\Users\wipe\Quora-Personal-Analytics>ruby QuoraStats.rb "firstname-lastname"
C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original
_require': no such file to load -- httparty (LoadError)
        from C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in
`require'
        from ./lib/Content.rb:1
        from C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in

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

不知何故，ruby bundle install 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

您似乎没有安装 bundler 。尝试运行 gem install bundler，然后重新运行 ruby hello.rb。

此外，您输入的最后两个命令将不起作用。 ruby require 'date' 将尝试运行文件“require”并将参数传递给它 'date'，而不是执行 require 'date'。要只执行一行 ruby​​，请使用 -e 标志，如下所示:

ruby -e "require 'date'"
