Rbenv错误的gem安装路径-找不到gem

Question

我在rbenv上遇到问题，我认为是require试图从我的系统gem而不是Shims读取它。

[我试图创建一个脚本文件而没有捆绑的开销-尽管我已经尝试添加Gemfile并将脚本和Gemfile放在同一目录中。

可重复的步骤：

1. brew install rbenv
2. 我的export PATH="$HOME/.rbenv/bin:$PATH"中的.zshrc
3. 将eval "$(rbenv init -)"添加到我的.zshrc
4. 来源：. ~/.zshrc
5. rbenv install 2.6.3
6. rbenv rehash
7. rbenv global 2.6.3
8. rbenv rehash为简洁起见
9. 关闭终端
10. 新终端：
    • ruby -v =“红宝石2.6.3p62”
    • rbenv version =“ 2.6.3（由$ HOME / Desktop / .ruby-version设置）”
11. which ruby =“ $ HOME / .rbenv / shims / ruby​​”
12. gem env
    • 安装目录：$ HOME / .rbenv / versions / 2.6.3 / lib / ruby​​ / gems / 2.6.0
    • 用户安装目录：$ HOME / .gem / ruby​​ / 2.6.0
    • RUBY EXECUTABLE：$ HOME / .rbenv / versions / 2.6.3 / bin / ruby​​
    • 可执行目录：$ HOME / .rbenv / versions / 2.6.3 / bin
    • SPEC CACHE目录：$ HOME / .gem / specs
    • 系统配置目录：$ HOME / .rbenv / versions / 2.6.3 / etc
    • RUBYGEMS平台：
      • 红宝石
      • x86_64-darwin-18
    • GEM路径：
      • $ HOME / .rbenv / versions / 2.6.3 / lib / ruby​​ / gems / 2.6.0
      • $ HOME / .gem / ruby​​ / 2.6.0
13. [gem install colorize-这个宝石似乎很好用]
14. gem install httparty
15. gem install pry

16. 文件头：

    #!/usr/bin/ruby
    
    require 'httparty'
    require 'colorize'
    require 'pry'
    

17. ./file.rb
18. HTTParty的堆栈跟踪

    /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/dependency.rb:319:in 'to_specs': Could not find 'multi_xml' (>= 0.5.2) among 17 total gem(s) (Gem::LoadError)
    Checked in 'GEM_PATH=$HOME/.gem/ruby/2.3.0:/Library/Ruby/Gems/2.3.0:/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/gems/2.3.0', execute `gem env` for more information
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/specification.rb:1442:in `block in activate_dependencies'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/specification.rb:1431:in `each'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/specification.rb:1431:in `activate_dependencies'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/specification.rb:1413:in `activate'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems.rb:196:in `rescue in try_activate'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems.rb:193:in `try_activate'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:125:in `rescue in require'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:39:in `require'
    from ./cdw-demo.rb:3:in `<main>'
    

19. 堆栈跟踪为撬

    /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- pry (LoadError)
    from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from ./cdw-demo.rb:4:in `<main>'
    

堆栈跟踪显示multi_xml可能是缺少的宝石，但已与httparty一起安装了

而不是使用系统已安装Ruby的/usr/bin/ruby，而是使用hashbang

#!/usr/bin/env ruby

这应该指向您的全球rbenv支持的Ruby。
