安装 CocoaPods 步骤整理

由于现在公司的项目开发不使用 Cocoapods 管理三方库文件, 所以自从去年到现在一直没有关心过 CocoaPods 的东东. 今天猛然发现之前安装 CocoaPods 都不适用用了, 而且也有一些坑坑, 所以小小记录一下.

步骤如下

移除现有的Ruby

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

使用淘宝镜像

ZK$ gem sources -a https://ruby.taobao.org/

验证当前ruby版本

ZK$ gem sources -l

成功后提示：

*** CURRENT SOURCES ***
https://ruby.taobao.org/

开始安装cocoapods

ZK$ sudo gem install cocoapods

注意这时候, 可能会因为你的 ruby 版本过低, 而出现问题, 如下:

Fetching: i18n-0.7.0.gem (100%)
Successfully installed i18n-0.7.0
Fetching: thread_safe-0.3.5.gem (100%)
Successfully installed thread_safe-0.3.5
Fetching: tzinfo-1.2.2.gem (100%)
Successfully installed tzinfo-1.2.2
Fetching: minitest-5.9.0.gem (100%)
Successfully installed minitest-5.9.0
Fetching: concurrent-ruby-1.0.2.gem (100%)
Successfully installed concurrent-ruby-1.0.2
Fetching: activesupport-5.0.0.gem (100%)
ERROR:  Error installing cocoapods:
activesupport requires Ruby version >= 2.2.2.

查看下版本

ZK$ ruby -v

结果, 果然过低

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

那过低我升级还不行嘛
首先查 list 一下我的版本

ZK$ rvm list known

竟然

-bash: rvm: command not found

好的, rvm 命令找不到, 那我安装 rvm 好伐, 敲如下命令即可安装:

ZK$ curl -L get.rvm.io | bash -s stable

安装好之后, 继续敲击上面那个 list 命令

ZK$ rvm list known

如果还是提示 命令找不到, 那就重启一下电脑 即可
敲了上面的命令, 就会如下一坨:

好的, 咱们安装 2.2.2 吧, 注意如果没有安装homebrew的话, 会先安装这个宝宝

ZK$ rvm install 2.2.2

结果如下:

Searching for binary rubies, this might take some time.

这样咱们的ruby同学就安装完成啦, 注意, 上面一坨不是一下生成的哦, 仔细看提示, 让咱们回车咱就回车, 让咱输入密码就输入密码哈, 这个时间比较长, 尤其是上面的Installing required packages: autoconf, automake, libtool, pkg-config, libyaml, readline, libksba, openssl...........等了大概5-9分钟啊, 以为罢工了呢. 总之一句话, 耐心等就是啦
接下来, 升级完ruby后不要忘了初衷哦, 我们来安装CocoaPods

ZK$ sudo gem install cocoapods

又是一大坨

到这里, 就已经安装完成啦, 好好享受CocoaPods带来的便捷吧
PS: 一粘贴终端里的文件到这里, 前面就会生成几行乱七八糟的代码, 哪位童鞋知道怎么才能不让他生成?

升级 cocoapods

• pod --version查看当前最新版本，如果不是最新，执行下面命令
• gem install cocoapods即可安装最新版本

---

注意，如果发现安装不成功，很可能是文件源失效了。

• gem source -l查看当前源，如我的是https://ruby.taobao.org/，如果过期失效可以切换其他的soucrce。切换方法如下：
• gem sources --remove移除当前源
• gem sources -a https://gems.ruby-china.org/添加新源
• sudo gem install cocoapods重新安装即可
