rbenv错误的gem安装路径-找不到gem

Question

我遇到了 rbenv 问题，我认为问题在于 require 试图从我的系统 gem 中读取而不是从 shims 中读取。

我正在尝试创建一个脚本文件而不需要捆绑的开销 - 尽管我尝试添加一个 Gemfile 并将脚本和 Gemfile 放在同一目录中。

可重现的步骤：

1. brew install rbenv
2. export PATH="$HOME/.rbenv/bin:$PATH" 在我的.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 可执行文件：$HOME/.rbenv/versions/2.6.3/bin/ruby
    • 可执行目录：$HOME/.rbenv/versions/2.6.3/bin
    • SPEC 缓存目录：$HOME/.gem/specs
    • 系统配置目录：$HOME/.rbenv/versions/2.6.3/etc
    • RUBYGEMS 平台：
      • 红宝石
      • x86_64-darwin-18
    • 宝石路径：
      • $HOME/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0
      • $HOME/.gem/ruby/2.6.0
13. gem install colorize - 这颗宝石似乎工作正常
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)

    from ./cdw-demo.rb:3:in `<main>'
    

19. Pry 的堆栈跟踪

    /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 gem，但它是与 httparty 一起安装的

不要使用/usr/bin/ruby这是系统安装的Ruby，使用hashbang

#!/usr/bin/env ruby

这应该指向你的全局 rbenv 支持的 Ruby。
