我已抛弃 Jekyll 换用 NextJS.

这里是本站开源: https://github.com/szhshp/NextJS-BlogTemplate-ProjectTitan

以下内容可能已经过时, 仅供参考

Ruby.Jekyll 的安装

Ruby.Download

点击这个网址下载：http://jekyll-windows.juthilo.com/1-ruby-and-devkit/

• 下载 Ruby 和 DevKit，注意版本要相同，安装和解压对应文件
• 64b 系统建议也用 32b
• 建议设置一下环境变量，把 Ruby 放到 Path 里面

Ruby.Init

ruby dk.rb init
ruby dk.rb install

经常 install 会失败，那是因为没有更新对应的 ruby list

到 DevKit 文件夹找到config.yml文件

加入以下代码，指向的是自己的 Ruby 的路径

---
- D:/Ruby22

注意横杠也要写进去

低版本可能需要写两行

Ruby.Finish

安装成功的话输入以下代码可以看到版本

D:\Tools_For_Work\Projs>ruby --version
ruby 2.2.2p95 (2015-04-13 revision 50295) [i386-mingw32]

Jekyll.Install

安装 Jekyll

D:\Tools_For_Work\Projs>gem install jekyll

这里会有各种错误

ERROR:  Could not find a valid gem 'jekyll' (>= 0), here is why:
 Unable to download data from http://ruby.taobao.org/ - bad respons
t Found 404 (http://ruby.taobao.org/specs.4.8.gz)

这样是因为对应的 Ruby Source 无法找到报 404 了

只需要修改 RubySource 即可

很多时候，在安装 gem 的过程中会出现找不到资源的 error，我们需要从另外一个 gem 服务器下载安装。 通过 gem sources 命令配置源，或通过修改 Gemfile 中的 source 语句可以实现。

常用的源

• http://rubygems.org/
• http://gems.github.com
• http://gems.rubyforge.org
• http://ruby.taobao.org

适合安装大多数常见的 gem[^ft]

显示当前使用的 sources

gem sources

添加一个 source

gem sources -a url 地址

删除一个 source

gem sources -r url 地址

更新 source cache

gem sources -u

添加几个 Source 后重新下载

Jekyll.Installation.Issues

plugins/convert.rb:32:in `module:Jekyll’: cannot load such file — jekyll/post (LoadError)

这次 Deploy 的时候这个问题困扰了我好久

大多数问题都是升级引发的问题

一旦我把对应的 Proj 进行 jekyll build 的时候就报错

后来搜了一下官方 Github 中的 Issue，发现了问题所在

相关连接：

• https://github.com/eggcaker/jekyll-org/issues/13
• https://github.com/jekyll/jekyll/issues/4116

原因是我拿 V2.X 的 Proj 并且用 V3.0 的 Jekyll 来 Build 了，并且对应的这个 post 文件夹也变了，因此处理方式就是干脆把所有所有转移到 3.0 的新 Proj 算了

所以只需要使用 Jekyll 建立一个新的 Proj

jekyll new MyBlog

就会在当前目录建立一个 MyBlog 的文件夹，并且里面已经有主要文件了

这个可恶的问题在 StackOverFlow 找了好久，最终还是官方的 Help Doc 比较全面

jekyll 3.0.0 | Error: Included file ‘_includes/JB/setup’ not found

这个也是上一个问题的连带问题

V2.X 里面的某些 Post 里面引用了以前的文件，因此现在 Not Found 是很正常的

D:\Tools_For_Work\Projs\blog>jekyll s
Configuration file: D:/Projs/blog/_config.yml
Source: D:/Projs/blog
   Destination: D:/Projs/blog/_site
 Incremental build: disabled. Enable with --incremental
  Generating……
  Liquid Exception: Included file '_includes/JB/setup' not found in D:/Tools_For
_Work/Projs/blog/_posts/2015-11-11-dicksday.md/#excerpt
jekyll 3.0.0 | Error:  Included file '_includes/JB/setup' not found

解决方法，把以前的 Post 的格式改成新的格式

错误的文件路径已经显示在 Error Msg 里面了

cannot load such file — jekyll-paginate (LoadError)

Gem install jekyll-paginate 

就可以了

Dependency Error! It looks like you don’t have redcarpet or one of its

   Dependency Error: Yikes! It looks like you don't have redcarpet or one of its
dependencies installed. In order to use Jekyll as currently configured, you'll n
eed to install this gem. The full error message from Ruby is: 'cannot load such
file -- redcarpet' If you run into trouble, you can find helpful resources at ht
tp://jekyllrb.com/help/!
 ERROR: YOUR SITE COULD NOT BE BUILT:
------------------------------------
redcarpet

一样 Gem install 对应的组件就行了

其他问题

一般官方的解答最为有效

https://github.com/jekyll/jekyll/search?utf8=%E2%9C%93&q=&type=Issues

Jekyll.Run

Proj 根目录使用jekyll b就可以 build

解决了以上问题终于可以 build 了

D:\Projs\blog>jekyll b
Configuration file: D:/Projs/blog/_config.yml
Source: D:/Projs/blog
   Destination: D:/Projs/blog/_site
 Incremental build: disabled. Enable with --incremental
  Generating……
done in 0.557 seconds.
 Auto-regeneration: disabled. Use --watch to enable.

然后jekyll s开启 server，然后使用 http://localhost:4000/访问

添加分页效果的时候遇到问题

提示说没有安装对应 module

Deprecation: You appear to have pagination turned on, but you haven't inc
luded the `jekyll-paginate` gem. Ensure you have `gems: [jekyll-paginate]` in yo
ur configuration file.

使用 gem install 之后依然报错

原因是没有在 Config 里面配置本地的 Gem，config 中加入一行 gems 声明

gems: [jekyll-paginate]

记得要配置分页细节

paginate: 12
paginate_path: "page:num"

2015-12-11 Error: mapping values are not allowed in this context at line 3 column 18

写新 post 的时候遇到问题

Regenerating: 1 file(s) changed at 2015-12-11 21:19:34 Error reading file
D:/Tools_For_Work/Projs/Github Blog/_posts/2015-12-11-wrapstringincf.md: (<unkno
wn>): mapping values are not allowed in this context at line 3 column 18
……error:
    Error: undefined method `each' for nil:NilClass
    Error: Run jekyll build --trace for more information.

跑到那篇文章里找到line 3 column 18发现对应 post 的 title 中不能含有分号(:)

删除后解决问题

Error: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/latest_specs.4.8.gz)

Win10 中初次使用时出现问题, 原因是证书文件缺失

Solution[^1]:

Download the cacert.pem file from http://curl.haxx.se/ca/cacert.pem. Save this file to C:\RailsInstaller\cacert.pem.

Now make ruby aware of your certificate authority bundle by setting SSL_CERT_FILE. To set this in your current command prompt session, type:

set SSL_CERT_FILE=C:\RailsInstaller\cacert.pem To make this a permanent setting, add this in your control panel.

注意要设置到系统变量而不是用户变量

2016-10-07 Error: undefined method `size’ for nil:NilClass (NoMethodError)

gem install时遇到错误

ERROR:  Error installing jekyll:
    invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError)

运行

gem env

然后到GEM PATHS里面删除 cache 文件夹[^3]

2018-01-24 关于 Jekyll 升级

大版本更新查看这篇文章

小版本更新直接:

gem update jekyll

2018-01-24 关于 Jekyll 3.7 的 LiveReload

一个小变化就是LiveReload, 每次修改后浏览器会自动刷新, 也算是更省事了

jekyll serve --livereload

jekyll s 遇到错误

>C:/Projects/_bg/ruby/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

>        from C:/Projects/_bg/ruby/bin/jekyll:22:in `<main>'

解决方法很简单:

gem install bundler

安装即可

2018-10-21 Updated

最近在使用一个 local gem 的时候报错:

  Dependency Error: Yikes! It looks like you don't have G:/Dev/GitRepos/Coding/tmp/_plugins/xxx.rb or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- bcrypt' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!
jekyll 3.8.2 | Error:  G:/Dev/GitRepos/Coding/tmp/_plugins/xxx.rb

这个 local gem 保存在 _plugins/xxx.rb 然后里面引用了一些其他的 gem, 错误信息中指明了错误的 gem 是 bcrypt, 重复执行 gem install bcrypt 无果.

最后发现是需要在根目录的 Gemfile 里面添加一句:

gem 'bcrypt'

这样就可以解决问题.

2019-10-13 Updated

Jekyll 4.0 升级遇到问题, 升级 4.0 之后官方建议使用 bundle 启动 local server

gem install jekyll bundler
bundle exec jekyll serve

遇到问题 Could not locate Gemfile or .bundle/ directory

你肯定是旧版本 jekyll 创建的 site

新建一个文件文件名为 Gemfile

source "https://gems.ruby-china.com"

gem "jekyll", "~> 4.0.0"

group :jekyll_plugins do
  gem "jekyll-feed", "~> 0.12"
end


## Windows and JRuby does not include zoneinfo files, so bundle the tzinfo-data gem

## and associated library.
install_if -> { RUBY_PLATFORM =~ %r!mingw|mswin|java! } do
  gem "tzinfo", "~> 1.2"
  gem "tzinfo-data"
end


## Performance-booster for watching directories on Windows
gem "wdm", "~> 0.1.1", :install_if => Gem.win_platform?

然后执行

Bundle install

Bundle 安装非常慢

换源, 换源! [^3]

执行下方这段即可

bundle config mirror.https://rubygems.org https://gems.ruby-china.com

.yml 文件中设置文件忽略

其实就是 ignore 参数, 例子:

exclude:
  - Gemfile
  - Gemfile.lock
  - node_modules
  - blog pull and debug.bat
