ios安装cocoaPods

1. 安装
a. 查看源

i.   gem sources -l

b. 删除源

i.   sudo gem sources -r https://rubygems.org/

c. 设置源

i.    sudo gem sources -a https://ruby.taobao.org --- 这里要换成新的源！！！

添加国内最新的源 ruby-china

sudo gem sources -a https://gems.ruby-china.org

d. 安装cocoaPad

-->    sudo gem install cocoapods -->

or ->升级gem sudo gem update --system 也是正常的

or ->安装CocoaPods执行正常：sudo gem install -n /usr/local/bin cocoapods

e. 设置

i. pod setup

2. cocoaPods使用

a. 搜索 <可略过>
i. pod search SDWebImage

b. 切换到项目的根目录 <可略过>
i. echo "pod' SDWebImage'" >Podfile

c. 安装
i. pod install

d. 升级
i. pod update

 
 升级了<优胜美地10.11系统>后出现:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/fileutils.
rb:245:in 'mkdir': Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal
-darwin-14 (Errno::EACCES)
 
使用下面的方法来解决:

1. 分别执行下面命令卸载cocoapods和xcodeproj，如果你的机器上面有多个版本，选择All versions卸载

$ sudo gem uninstall cocoapods   $ sudo gem uninstall xcodeproj

2. 分别执行下面命令安装xcodeproj和cocoapods

$ sudo gem install xcodeproj   $ sudo gem install cocoapods

接下来尝试执行pod install，如果您还遇到下面的错误：

1 2	Error loading the plugin with path '/Library/Ruby/Gems/2.0.0/gems/cocoapods-plugins-0.3.1/lib/cocoapods_plugin.rb'. Errno::EACCES - Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-14

运行命令$ gem update --system即可。

 

查看当前安装了哪些版本:

gem list --local | grep cocoapods

解决 cocoapods安装路径问题:

解决方法:在路径里面手动添加/usr/local/bin

如果不行就在终端执行更改命令:

sudo gem uninstall cocoapods

sudo gem install -n /usr/local/bin cocoapods

sudo chmod +rx /usr/local/bin/

// -------------------------------------------

ERROR:  While executing gem ... (Errno::EPERM)

    Operation not permitted - /usr/bin/xcodeproj

报上边这错误 执行下面的代码: 

 sudo gem install -n /usr/local/bin cocoapods

SuperdeMacBook-Pro:.cocoapods super$ sudo gem install cocoapods

SuperdeMacBook-Pro:.cocoapods super$ sudo gem install -n /usr/local/bin cocoapods

ERROR: While executing gem ... (Gem::DependencyError) Unable to resolve dependencies: cocoapods requires claide (< 2.0, >= 1.0.1), cocoapods-downloader (< 2.0, >= 1.1.2), cocoapods-trunk (< 2.0, >= 1.1.1), molinillo (~> 0.5.3), xcodeproj (< 2.0, >= 1.4.0), fourflusher (~> 2.0.1)

解决的链接:http://blog.csdn.net/miao_em/article/details/53282730

解决的命令:sudo gem update --system

// ----------------------------------------------遇到的另外一个报错

添加国内ruby源 gem sources --add https://gems.ruby-china.org

报错：

Error fetching https://gems.ruby-china.org/:

bad response Not Found 404 (https://gems.ruby-china.org/specs.4.8.gz)

原因是 ruby-china 更换了域名

https://gems.ruby-china.com

命令替换为 gem sources --add https://gems.ruby-china.com 解决
