我最近发现jekyll，在完美使用几个月后，该命令在我的计算机上不再起作用。
每当我尝试运行jekyll命令时，它都会说：
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs':
Could not find 'jekyll' (>= 0) among 34 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/Mael/.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/dependency.rb:328:in `to_spec'

from /usr/local/bin/jekyll:22:in `'
我使用的是macOS Sierra（10.12.6）。
Xcode已安装
我的计算机上安装了Xcode：
$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
重新安装Jekyll
检查Ruby版本并（重新）安装捆绑器
因此，我尝试像第一次那样重新安装Jekyll：
$ ruby -v
ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin16]
$ sudo gem install bundler
Successfully installed bundler-1.17.1
Parsing documentation for bundler-1.17.1
Done installing documentation for bundler after 4 seconds
1 gem installed
创建一个宝石文件
我创建了一个包含以下内容的Gemfile：
gem 'github-pages'
source 'https://rubygems.org'
捆绑安装（问题来了）
并在包含Gemfile的目录中运行：
$ bundle install
在这里，安装不起作用，它说：
An error occurred while installing commonmarker (0.17.13), and Bundler cannot continue.
Make sure that `gem install commonmarker -v '0.17.13' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
github-pages was resolved to 192, which depends on
jekyll-commonmark-ghpages was resolved to 0.1.5, which depends on
jekyll-commonmark was resolved to 1.2.0, which depends on
commonmarker
所以我尝试了gem install commonmarker -v '0.17.13' --source 'https://rubygems.org/'命令，它说：
Building native extensions. This could take a while...

我注意到我的（2.0.0）目录中有几个jekyll和github-pages gems：/Library/Ruby/Gems/2.0.0/gems
github-pages-146
github-pages-health-check-1.3.5
...
jekyll-3.4.5
jekyll-avatar-0.4.2
jekyll-coffeescript-1.0.1
[and several other jekyll directories]
...
但是不在我的/Library/Ruby/Gems/2.3.0/gems （2.3.0）目录中！（似乎是GEM_PATH运行jekyll命令时针对的对象）
所以，也许我做了一些改变版本的事情。（我最近安装了（osxfuse并且sshfs通过brew），我不知道是否与该问题有关？）
我对Ruby，Gems系统等一无所知。也许解决方案很明显，但是我尝试了几项都没有成功。
（抱歉，它有点长，但是我想尽可能清楚一些！）
