ruby - githubpages+jekyll搭建个人博客 再jekyll s时遇到问题

Question

1.
想做个个人博客，装了git、ruby、gem、jekyll
装jekyll的过程：

gem install jekyll
cd d:website
jekyll new myweb
jekyll serve

fork了别人的一个博客，运行

jekyll serve

出现了以下错误：

D:/softwares/Ruby22-x64/lib/ruby/gems/2.2.0/gems/bundler-1.12.5/lib/bundler/spec_set.rb:95:in `block in materialize': Could not find RedCloth-4.2.9 in any of the sources (Bundler::GemNotFound)

但是奇怪的是，从gem list中查看，我已经装了redcloth。
gem list

bigdecimal (default: 1.2.6)
bundler (1.12.5)
colorator (1.1.0)
directory_watcher (1.5.1)
ffi (1.9.14 x64-mingw32)

io-console (default: 0.4.3)
jekyll (3.2.1)
jekyll-paginate (1.1.0)

rubygems-update (2.6.6)
safe_yaml (1.0.4)
sass (3.4.22)
syntax (1.0.0)

对git和ruby不是很了解，也不知道是不是配置的顺序有错误，但是很想自己做个博客。
实在不知道怎么解决了，请教各位大神。

• 系统：win 10

• ruby:2.2.5

• bundler 1.12.5

• gem 2.6.6

Answer 1

I also installed the bundle.
I switched to hexo.
In the process of using hexo, I found that if there is no response when typing
localhost:4000
in the browser, it may be because the port is occupied.
Thank you everyone.

Answer 2

bundle install

Answer 3

I encountered the problem jekyll serve不能运行，但是是jekyll-paginate before, and then Googled it and reprinted this article https://dotos.github.io/jekyl...

Solved with bundle

# 1.如果没有安装bundle
gem install bundle
# 2.jekyll-blog目录创建Gemfile文件，内容参考链接
# 3.运行bundle，安装Gemfile里的插件(姑且叫插件吧，我也不知道叫啥~_~!)
bundle install 
# 4.打开服务
bundle exec jekyll serve
# or
jekyll serve
