OS X 10.11 安装Cocoapods 出现问题的解决方法

转自：http://blog.csdn.net/NSNirvana/article/details/46873071

今天尝试用 Cocoapods安装个第三方库.. 输入pod install， 发现 command not find。 WTF！

估计是升级10.11后Cocoapods被干掉了。

我输入 sudo gem install cocoa pods 之后，出现如下问题：

ERROR:  While executing gem ... (Gem::DependencyError)

    Unable to resolve dependencies: cocoapods requires cocoapods-core (= 0.33.1), claide (~> 0.6.1), cocoapods-downloader (~> 0.6.1), cocoapods-plugins (~> 0.2.0), cocoapods-try (~> 0.3.0), cocoapods-trunk (~> 0.1.1), nap (~> 0.7)

解决方法：sudo gem update --system

  

但是出现了另一个错误：

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

    Operation not permitted - /usr/bin/xcodeproj

在Stackoverflow上找到了解决方法：

在终端中输入：sudo nvram boot-args="rootless=0"; sudo reboot

然后你的电脑会重启

之后再输入 sudo gem install cocoapods -V 

就可以了

不放心的话输入

pod --version

0.37.2 //显示出版本就说明成功了

但是之后我pod install的时候又花式出错

[!] Unable to add a source with url `https://github.com/CocoaPods/Specs.Git` named `master`.

You can try adding it manually in `~/.cocoapods/repos` or via `pod repo add`.

我尝试按提示的方法

pod repo add master https://github.com/CocoaPods/Specs.git

然而还是有错..

[!] /usr/bin/git clone http://git.oschina.NET/akuandev/Specs.git master

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

最后的解决方法：

sudo xcode-select -switch /Applications/Xcode-beta.app/Contents/Developers

后面的地址你可以打开Xcode显示包内容，找到那个文件夹拖到终端里面比较不容易错。

CocoaPods 0.38.0.beta.2 is available.

To update use: `gem install cocoapods --pre`

[!] This is a test version we'd love you to try.

For more information see http://blog.cocoapods.org

and the CHANGELOG for this version http://git.io/BaH8pQ.

最后终于修成正果..

至于一开始输入 sudo gem install cocoapods 没反应需要修改为淘宝镜像的问题，请百度Cocoapods参阅其它文章..

结合方案二：

 

安装cocoa pods时出现Operation not permitted - /usr/bin/xcodeproj的问题

转自：http://blog.csdn.net/prl18353364833/article/details/53905487

在更新完ruby，更换Ruby镜像－－淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。官方的需要FQ。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)

安装cocoa pods时，

  在命令行中输入：

  安装：sudo gem install cocoapods报Operation not permitted - /usr/bin/xcodeproj这个错误，解决办法为：

用

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

这段命令代替

sudo gem install cocoa pods 

 就完美解决了

安装cocoapods的步骤为：

1、更新ruby   

sudo gem update --system

2、

更换Ruby镜像－－淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。官方的需要FQ。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)

  需要的命令行：

  gem sources --remove https://rubygems.org/ 
  gem sources -a https://gems.ruby-china.org/ 
  gem sources -l  （用来检查使用替换镜像位置成功）

  出现

*** CURRENT SOURCES ***

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

则说明成功了

3、安装cocoapods  命令行： sudo gem install -n /usr/local/bin cocoapods --pre

终端打印：

MacintoshdeiMac:~ Mac$ sudo gem install -n /usr/local/bin cocoapods --pre
