ruby - Github-Pages 在本地运行 Jekyll 时出错

Question

我正在尝试在本地运行我的 Github-pages 网站。我让它在另一台在 Windows x64 上使用 Ruby 2.1.0 的机器上运行。今天我想在运行 Ruby 2.2.0 的家用机器上本地运行。在 nokogiri 出现一些问题后，我在本地提取了我的 repo，运行了 bundle install 我能够通过一个干净的 bundle install。然后我继续运行命令 bundle exec jekyll serve -w。运行此命令后，我收到以下错误:

/Users/<me>/.rvm/gems/ruby-2.2.0@global/gems/commander 4.1.6/lib/commander/runner.rb:385:in block in require_program': program version required (Commander::Runner::CommandError)

    from /Users/<me>/.rvm/gems/ruby-2.2.0/bin/ruby_executable_hooks:15:in <main>'

我开始相信这个问题与我的设置无关，而是与 ruby​​ 2.2.0 上的 jekyll 不兼容。任何帮助将不胜感激。

谢谢!

所以在进一步挖掘之后，我遗漏了一个简单的步骤。运行命令 bundle install 后，我需要运行 bundle update。完成此操作后，jekyll 和其他依赖项的版本将升级到正确的版本，然后我就可以运行我的 bundle exec jekyll serve -w 命令而不会出现任何错误。

这看起来很奇怪，初始安装命令不会安装最新版本。
