Jekyll serve error: can't find gem jekyll (>= 0.a) (Gem::GemNotFoundException

Question

在执行 sudo jekyll serve 时出现以下错误：

Users/myusername/.rvm/rubies/ruby-2.4.2/lib/ruby/site_ruby/2.4.0/rubygems.rb:271:in 'find_spec_for_exe': can't find gem jekyll (>= 0.a) (Gem::GemNotFoundException)
from /Users/myusername/.rvm/rubies/ruby-2.4.2/lib/ruby/site_ruby/2.4.0/rubygems.rb:299:in 'activate_bin_path'
from /Users/myusername/.rvm/gems/ruby-2.4.2/bin/jekyll:23:in '<main>'
from /Users/myusername/.rvm/gems/ruby-2.4.2/bin/ruby_executable_hooks:15:in 'eval'
from /Users/myusername/.rvm/gems/ruby-2.4.2/bin/ruby_executable_hooks:15:in '<main>'

如果有帮助：

• jekyll -v returns jekyll 3.6.2
• ruby -v returns ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin15]
• gem -v returns 2.6.14
• bundle -v returns Bundler version 1.16.0

在我的 Gem 文件中我有：

ruby '2.4.2'

rmv list 输出：

ruby-2.3.5 [ x86_64 ]
=* ruby-2.4.2 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

Answer 1

我终于解决了这个问题：

sudo rm -rf _site
bundle update
bundle exec jekyll serve

然后总是使用 bundle exec jekyll serve 而不是 sudo jekyll serve 或 jekyll serve。

感谢 in this post 的回答，我得到了这个解决方案。
