gem安装依赖失败

很久没有写博客了，最近也新换了电脑，重新把博客从github上拉下来。

安装了jekyll后，满心欢喜的执行jekyll serve 终端里得来的却是无情的红色报错，心里顿时一凉，好不容易想写文章的热情也被浇灭。

终于2天后，还是静下心来把这些问题解决。

  1. run gem install bundle

  2. remove Gemfile.lock

  3. run sudo bundle install

这时再启动，发现报错

/Library/Ruby/Gems/2.3.0/gems/bundler-1.17.1/lib/bundler/runtime.rb:319:in `check_for_activated_spec!': You have already activated i18n 1.1.1, but your Gemfile requires i18n 0.9.5. Prepending `bundle exec` to your command may solve this. (Gem::LoadError)

	from /usr/local/bin/jekyll:22:in `load'
	from /usr/local/bin/jekyll:22:in `<main>'

这时再执行 gem unintall i18n，选择移除1.1.1版本

大功告成！
