纯属菜鸟自己记录为以后失忆症犯了的时候看看的：）刚开始接触ruby 所以从安装开始网上找了一些guide 自己也写一个自己的心得
首先比较简单的安装 ，安装包地址：https://www.ruby-lang.org/en/documentation/installation/#rubyinstaller or http://railsinstaller.org/en
我选的：
下载安装一下一部没有特殊的这里省略了，中间忽略了一个ssh验证导致后来的gem不能使用（我想应该是这样的）。。。。。。下边就介绍一下如何解决：
错误：

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
server certificate B: certificate verify failed (https://rubygems.org/gems/rake-

An error occurred while installing rake (10.4.2), and Bundler cannot continue.
Make sure that `gem install rake -v '10.4.2'` succeeds before bundling.

解决方法：
https://gist.githubusercontent.com/raw/867550/win_fetch_cacerts.rb
我把它开背出来新建了一个同名文件放到桌面上
require 'net/http'
# create a path to the file "C:\RailsInstaller\cacert.pem"
cacert_file = File.join(%w{c: RailsInstaller cacert.pem})#可以根据自己的实际路径进行更改
Net::HTTP.start("curl.haxx.se") do |http|
resp = http.get("/ca/cacert.pem")
if resp.code == "200"
open(cacert_file, "wb") { |file| file.write(resp.body) }
puts "\n\nA bundle of certificate authorities has been installed to"
puts "C:\\RailsInstaller\\cacert.pem\n"
puts "* Please set SSL_CERT_FILE in your current command prompt session with:"
puts " set SSL_CERT_FILE=C:\\RailsInstaller\\cacert.pem"
puts "* To make this a permanent setting, add it to Environment Variables"
puts " under Control Panel -> Advanced -> Environment Variables"
else
abort "\n\n>>>> A cacert.pem bundle could not be downloaded."
end
end

不过在后来的安装还是不稳定于是决定更换成国内的淘宝源：
C:\Users\IBM_ADMIN>gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources
C:\Users\IBM_ADMIN>gem sources
*** CURRENT SOURCES ***
C:\Users\IBM_ADMIN>gem source -l
*** CURRENT SOURCES *** 这两个命令都可以查看当前的源
C:\Users\IBM_ADMIN>gem sources --add https://ruby.taobao.org/ 也可以 gem source -a https://ruby.taobao.org/
https://ruby.taobao.org/ added to sources
C:\Users\IBM_ADMIN\wjtest1>gem sources -u
source cache successfully updated
C:\Users\IBM_ADMIN>gem sources
*** CURRENT SOURCES ***

C:\Users\IBM_ADMIN>
现在在重新试这创建之前的项目
C:\Users\IBM_ADMIN>rails new wjtest1
