今天安裝jazzy的時候碰到一點問題巾陕，記錄下來踢匣，希望對大家能夠有點幫助

本人的操作系統是OS X EI Capitan似枕，os 10.11.6

按照jazzy的開發(fā)指南，在終端輸入：

sudo gem install jazzy

結果產生如下的錯誤

Building native extensions.? This could take a while...

ERROR:? Error installing jazzy:

按照錯誤的提示趣苏，應該是我的ruby管理包版本比較舊狡相，那么就開始升級吧

要升級ruby，需要安裝rvm

showxjndeMacBook-Air:Applications showxjn$ ruby -v

ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]

showxjndeMacBook-Air:Applications showxjn$ rvm -v

-bash: rvm: command not found

showxjndeMacBook-Air:Applications showxjn$ curl -L get.rvm.io | bash -s stable

上述命令依次是查詢ruby版本食磕，查詢rvm版本尽棕，安裝rvm

安裝好了之后

showxjndeMacBook-Air:Applications showxjn$ source ~/.bashrc

showxjndeMacBook-Air:Applications showxjn$ source ~/.bash_profile

showxjndeMacBook-Air:Applications showxjn$ rvm -v

rvm 1.29.2 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io/]

更改下路徑，rvm安裝成功了彬伦，接下來滔悉，更新ruby
