iOS 学习笔记二【cocopods安装使用和安装过程中遇到的问题及解决办法】

在osx 10.11之前cocopods问题不多，但是升级到11之后的版本，之前的cocopods大多用不了，需要重新安装，对于我这种使用测试版系统的技术狂来说，每次都需要重新安装很多东西，

当然，cocopods也避免不了安装很多次了。

对于新手来说，使用cocopods开发，还是节省了相当多的开发时间，以下便是cocopods安装和安装过程中遇到的问题及解决办法：

1、cocopods 安装：/article/5219791.html

2、出现以下问题，大家不要慌：

boai:~ boai$ sudo gem install cocoapods
ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from http://ruby.taobao.org/ - bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)
boai:~ boai$ sudo gem install cocoapods
ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:
Unable to download data from http://ruby.taobao.org/ - bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)
boai:~ boai$ sudo gem update --system
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)

解决办法：

（1）先执行下面两行代码：

sudo gem sources -r https://rubygems.org
sudo gem sources -a http://rubygems.org
（2）执行过程如下：

boai:~ boai$ sudo gem sources -r https://rubygems.org source https://rubygems.org not present in cache
boai:~ boai$ sudo gem sources -a http://rubygems.org https://rubygems.org is recommended for security over http://rubygems.org 
Do you want to add this insecure source? [yn]  y

最后会提示

Do you want to add this insecure source? [yn]
你选择 y就行了
然后出现：

http://rubygems.org added to sources

这就说明成功了，就可以执行下面的安装了。

（3）安装cocopods

执行下面的语句：

sudo gem install cocoapods

会出现下面的界面：（激动。。。）

看到最后一行代码，你就放120个心吧。。。

然后就可以查看你的pods版本了：

输入：pod

然后会出现下面的代码：

boai:~ boai$ pod
Usage:

$ pod COMMAND

CocoaPods, the Cocoa library package manager.

Commands:

+ cache      Manipulate the CocoaPods cache
+ init       Generate a Podfile for the current directory.
+ install    Install project dependencies to Podfile.lock versions
+ ipc        Inter-process communication
+ lib        Develop pods
+ list       List pods
+ outdated   Show outdated project dependencies
+ plugins    Show available CocoaPods plugins
+ repo       Manage spec-repositories
+ search     Search for pods.
+ setup      Setup the CocoaPods environment
+ spec       Manage pod specs
+ trunk      Interact with the CocoaPods API (e.g. publishing new specs)
+ try        Try a Pod!
+ update     Update outdated project dependencies and create new
Podfile.lock

Options:

--version    Show the version of the tool
--verbose    Show more debugging information
--no-ansi    Show output without ANSI codes
--help       Show help banner of specified command
boai:~ boai$

这就安装成功了，就可以正常使用pod了。。。

[b]3、接下来就可以在项目中使用了，[/b]

打开终端：

cd 你的项目路径

boai:~ boai$ cd /Users/boai/Documents/博爱项目/BAPDCViewTest

然后：输入touch podfile

boai:BAPDCViewTest boai$ touch podfile

boai:BAPDCViewTest boai$ pod install

接下来出现：

Last login: Fri Nov 20 11:02:59 on ttys006

boai:~ boai$ cd /Users/boai/Documents/博爱项目/BAPDCViewTest

boai:BAPDCViewTest boai$ touch podfile

boai:BAPDCViewTest boai$ pod install

Updating local specs repositories

Analyzing dependencies

Downloading dependencies

Generating Pods project

Integrating client project

[!] Please close any current Xcode sessions and use `BAPDCViewTest.xcworkspace` for this project from now on.

Sending stats

Pod installation complete! There are 0 dependencies from the Podfile and 0 total

pods installed.

[!] [!] The Podfile does not contain any dependencies.

boai:BAPDCViewTest boai$

这就成功了，然后再看看你的项目路径里面，是不是多出来很多文件？

如下图：



然后双击***.workspace 文件就可以使用pods了！

好了，大功告成！
