CocoaPods最新安装教程 (10月11日)

打开终端

移除现有 Ruby 默认源

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

使用新的源

淘宝源还是能用,就是比较慢:
$ gem sources -a https://ruby.taobao.org/
//备用地址:更新为新的源地址
//$ gem sources -a https://gems.ruby-china.org/

验证新源是否替换成功

$ gem sources -l //查看当前的源地址

安装 CocoaPods

$ sudo gem install cocoapods

$ pod setup

#######备注：苹果系统升级 OS X EL Capitan 后安装改为:

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

$ pod setup

更新 gem

$ sudo gem update --system

新建工程，并在终端用 cd 指令到文件夹内

$ pod search 第三方

新建 Podfile 文件

$ pod init

编辑 Podfile 文件，并写入要添加的第三方库

platform:ios, '8.0'

pod 'AFNetworking', '~> 2.3.1'<-------第三方

导入第三方库

$ pod install

$ pod install --verbose --no-repo-update

错误解决方法:

错误一

[!] The `AllBlue [Debug]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.debug.xcconfig'. This can lead to problems with the CocoaPods installation
Use the $(inherited) flag, or
Remove the build settings from the target.

[!] The `AllBlue [AutoDebug]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.autodebug.xcconfig'. This can lead to problems with the CocoaPods installation
Use the $(inherited) flag, or
Remove the build settings from the target.

[!] The `AllBlue [Release]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
Use the $(inherited) flag, or
Remove the build settings from the target.

[!] The `AllBlue [AutoRelease]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods/Pods.autorelease.xcconfig'. This can lead to problems with the CocoaPods installation

• 造成的原因是:target的设置覆盖了 pod的设置

解决办法:

• 在Build Settings -> Other linker flags 中添加$(inherited)
• 修改完毕后,终端执行pod install
• 重新打开工程

错误二

遇到 Error installing pods:activesupport requires Ruby version >=2.2.2

• 造成的原因是:没有安装 RVM baby 版本管理器

解决办法:

1.安装 RVM baby 版本管理器

$curl -L get.rvm.io | bash -s stable

• 安装完成 出现下面这行提示以下

In case of problems: https://rvm.io/helpandhttps://twitter.com/rvm_io

• 执行

$source ~/.bashrc

$source ~/.bash_profile

• 测试是否安装正常

$rvm -v

• //提示以下

rvm 1.27.0 (latest) by Wayne E. Seguin, Michal Papis[https://rvm.io/]

2.用RVM升级Ruby查看当前ruby版本

$ruby -v

$rvm list known

• //提示以下

# MRI Rubies

# for forks use: rvm install ruby-head---url https://github.com/github/ruby.git --branch 2.2

# JRuby

• 安装ruby 2.2.2 执行

$rvm install 2.2.2

• 如果打印

ruby-2.2.2 - #validate archive
