CocoaPods错误集锦

今天升级了Mac OS X 10.10-Yosemite以后运行pod install遇到下面的错误： 

1

2

3

/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)

一番折腾后找到解决方案如下：

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 

1

2

3

$ sudo gem uninstall cocoapods

 

$ sudo gem uninstall xcodeproj

2. 分别执行下面命令安装xcodeproj和cocoapods 

1

2

3

$ 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。

直奔主题，列举出平时使用CocoaPods遇到的一些问题。

问题一：更新gem报错(sudo gem update --system)

• 错误一： 
  * 错误信息： 
  * ERROR: While executing gem … (Errno::EPERM) 
  Operation not permitted - /usr/bin/xcodeproj 
  * 解决办法： 
  * 执行sudo gem install -n /usr/local/bin cocoapods命令 
  
  • 错误二： 
    
    • 错误信息： 
      
      • ERROR: While executing gem … (Errno::EPERM) 
        Operation not permitted - /usr/bin/update_rubygems
    • 解决办法： 
      
      • 安装Homebrew（Homebrew installs the stuff you need that Apple didn’t.） 
        objc 
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 

      • 安装roby 
        objc 
brew install ruby 

      • 此时正常的话，会提示：RubyGems system software updated，恭喜你，gem更新成功了！

问题二：pod install报错

错误信息如下：

分析

• CocoaPods与ruby版本

• 那么问题来了，* This is a bug with 0.39 and ruby 2.3.0 - #4689 *

解决办法

如果不是0.39.0 VS 2.3.0

• 在终端中依次执行以下命令即可

<code class="hljs bash has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">cd</span> ~/.cocoapods/reposrm -rf masterpod setup</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

如果是0.39.0 VS 2.3.0

方法一：改变CocoaPods版本

• 卸载当前版本

  sudo gem uninstall cocoapods

• 下载指定版本(如：0.39.0)

  sudo gem install cocoapods -v 0.39.0

方法二：改变ruby版本

• 如何改变ruby版本呢？答案是安装ruby管理器RVM

安装RVM

• 什么是RVM? 
  
  • RVM:Ruby Version Manager 也就是ruby版本管理工具

• 安装RVM

  • 在终端中执行命令:

  curl -L https://get.rvm.io | bash -s stable

  • 安装完成之后，载入RVM环境

  source ~/.rvm/scripts/rvm

  • 测试是否安装正确 
    

• 查询ruby信息

  • 查询已知的ruby版本

  rvm list known

  • 查询已经安装的ruby

  rvm list

• 安装某版本的ruby

  rvm install 2.0.0

• 卸载某版本的ruby

  rvm remove 2.3.0

• 设置ruby版本

  rvm 2.0.0 --default

只要不是0.39.0 VS 2.3.0,应该都可以安装成功的！

问题三：更改ruby版本之后，pod install还是报错！

错误信息如下：

解决办法

• 删除cocoapods gem uninstall cocoapods
• 安装 rvm
• 重新安装cocoapods gem install cocoapods
• 执行 pod setup命令

错误四：Podfile文件格式问题

如果你把CocoaPods版本升级到CocoaPods 1.0.0.beta.6，那么之前的Podfile格式就会有问题

• CocoaPods 1.0.0**之前**的版本，你的Podfile可能是这样的：
