osx升级到10.10后，用pod install报错终于解决的方法

Posted 2020-09-16 slgkaifa

 先依照这个文章做：http://blog.csdn.net/dqjyong/article/details/37958067

大概过程例如以下：

1. Open Xcode 6
2. Open Preferences
3. Click the Locations tab
4. Change the Command Line Tools version to Xcode 6.0
5. Uninstall cocoapods
   a. $ sudo gem uninstall cocoapods
   
6. Install xcodeproj
   a. $ sudo gem install xcodeproj
   
7. Install cocoapods
   a. $ sudo gem install cocoapods
   
8. Run pod --version to verify that it worked

假设你运行到第6步：sudo gem install xcodeproj 成功，可是到第七步：$ sudo gem install cocoapods 时失败，错误信息例如以下：

ERROR:  Could not find a valid gem \'cocoapods\' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - Errno::ETIMEDOUT: Operation timed out - connect(2) (https://rubygems.org/latest_specs.4.8.gz)
ERROR:  Possible alternatives: cocoapods

意识是说在官方源中找不到我们须要的源，这时怎么办呢，网上找到一篇博客，这样做的。切换官方源。也即是改变源的获取地址

这时候我们须要改变 gem source, 參考[4], [5]。

须要在终端中运行例如以下命令: 

$ gem sources -l

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

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

$ gem sources -l

接下来输入下面命令：

$ pod setup

This process will likely take a while as this command clones the CocoaPods Specs repository 

into ~/.cocoapods/ on your computer. [6]

至此CocoaPods安装完成。

注： 假设漏掉 "$ pod setup" 命令，而直接运行"$ pod init"

会有类似下面的error信息：

"$ pod init

Setting up CocoaPods master repo

[!] /usr/bin/git clone \'https://github.com/CocoaPods/Specs.git\' master --depth=1

 

Cloning into \'master\'...

 

error: RPC failed; result=52, HTTP code = 0

 

fatal: The remote end hung up unexpectedly

 

/Library/Ruby/Gems/2.0.0/gems/claide-0.6.1/lib/claide/command.rb:304:in `handle_exception\': undefined method `verbose?\' for nil:NilClass (NoMethodError)

from /Library/Ruby/Gems/2.0.0/gems/claide-0.6.1/lib/claide/command.rb:284:in `rescue in run\'

from /Library/Ruby/Gems/2.0.0/gems/claide-0.6.1/lib/claide/command.rb:274:in `run\'

from /Library/Ruby/Gems/2.0.0/gems/cocoapods-0.33.1/lib/cocoapods/command.rb:48:in `run\'

from /Library/Ruby/Gems/2.0.0/gems/cocoapods-0.33.1/bin/pod:33:in `<top (required)>\'

from /usr/bin/pod:23:in `load\'

from /usr/bin/pod:23:in `<main>\' "

以上操作步骤完毕后在进行：$ sudo gem install cocoapods

这时就成功了！

剩下的就是和曾经的一样在project文件夹下，建Podfile，运行pod install，打开xworkspace等，顺利完毕！

！。
