在ubuntu on windows 上安装jekyll

已知问题

安装ruby之后，重新启动ubuntu on windows，输入ruby命令，提示找不到。

发现的解决办法 执行下面命令

source /home/xxxx/.rvm/scripts/rvm

把xxxx换成自己的用户名

为什么热衷于折腾jekyll呢，因为他们网站下面有句话 GitHub Pages are powered by Jekyll

戳开有惊喜。

环境

使用Ubuntu On Windwos,戳这里了解详细信息

这里讲述怎么打开ubuntuOnWindows

在使用过程中，感觉这货就像是windows上的一个软件，非常方便。

假如说你把这货玩儿坏了，可以使用命令

lxrun /uninstall /full

进行卸载

然后使用命令

lxrun /install

进行安装。

安装方法

本来想着在ubuntu上安装ruby，有啥好难的，使用 sudo apt-get install ruby不能就安装好了？

我开始也是这么想的……

如果你看到了这篇文章，没准儿你碰到了跟我一样的问题。

撰写本文时，通过上面的命令，只能安装1.9.3这个版本的，but最新版本的ruby已经2.3了，jekyll也已经嫌弃这个版本了……

然后开始各种百度、谷歌查找怎么解决，费老劲了。忍不住在吐槽一项百度，垃圾呀……怪不得费尽心机把谷歌弄出去，不然早倒闭了。广告也就忍了，检索出来基本没啥有用的东西。

安装ruby

嗯~~在开搞之前，一定要先把ubuntu的源给修改成国内的源，不然会是非常漫长的过程，具体步骤google以下大把的都是

尝试了两种解决方案

1. 使用 https://launchpad.net/~brightbox/+archive/ubuntu/ruby-ng这里给出的方案，能够安装，但在使用gem安装的程序过程中，出现找不到命令的问题，应该时哪个地方配置除了问题了，对linux了解不多，没有多费心寻找解决方案。不过看样子应该时可行方案之一。
2. 使用rvm安装，Ruby enVironment (Version) Manager (RVM)07年出现的东西，用起来很省心，中间需要两次输入密码进行授权。戳这里有安装教程 我用的这个。

ruby安装完成之后，需要安装ruby-dev，执行命令 rvm install ruby-dev就能安装好了

安装jekyll

http://jekyllrb.com/

直接照着上面的安装就好了，新版本的貌似要安装bundler，不知道干啥用的。

只使用命令 jekyll server --force 看起来一样正常 。

这里最好把gem的源设置成国内的，不然可能会碰到伟大的长城。

我用的是这个 http://mirrors.aliyun.com/rubygems/

下面是具体设置步骤

gem sources --remove https://rubygems.org/

gem sources -a https://ruby.taobao.org/ 据说淘宝的已经停止维护了，ssl证书貌似除了问题

gem sources --add http://mirrors.aliyun.com/rubygems/

gem sources -l

异常处理

bundle install时如果碰到以下错误
