[fastlane] [gem] [rvm] [ruby]

使用fastlane 实现快速持续的更新、在安装过程中 出现的一系列问题：

1.安装fastlane ：sudo gem install fastlane

-错误：ERROR: Failed to build gem native extension.

#不要添加多个gem 源

#开始以为是gem 源的问题
#查看gem源
gem sources
# 删除默认的gem源
gem sources --remove http://rubygems.org/
# 增加taobao作为gem源
gem sources -a https://ruby.taobao.org/
# 查看当前的gem源
gem sources
*** CURRENT SOURCES ***

http://ruby.taobao.org
# 请确保只有 ruby.taobao.org

# 清空源缓存
gem sources -c
# 更新源缓存
gem sources -u

错误仍然存在；

然后查到是ruby版本的问题

2.更新ruby版本，安装rvm

http://blog.csdn.net/lissdy/article/details/9191351，

http://stackoverflow.com/questions/3696564/how-to-update-ruby-to-1-9-x-on-mac

curl -L get.rvm.io | bash -s stable

测试是否安装正常 rvm -v

3.rvm install ruby-2.1.4，报下面的错误

?  ~ git:(master) ? rvm install ruby-2.1.4
Searching for binary rubies, this might take some time.

ERROR: ‘/bin‘ is not writable - it is required for Homebrew, try ‘brew doctor‘ to fix it!
Requirements installation failed with status: 1.

然后这样处理：

$ brew install openssl  # if you want to install all dependencies run ‘rvm requirements‘
$ rmv reinstall|install ruby-2.1.4

最后就顺利安装fastlane了。
