最近在安装cocoa pods,安装时遇到了一点问题,通过上面网址的步骤一步步操作,然后到第八步没怎么看明白,就按自己的理解安装成功了,下面是我安装cocoapods的具体步骤,希望能帮到大家
1.打开终端
2 移除现有 Ruby 默认源 输入以下指令
$gem sources --remove https://rubygems.org/
3.使用新的源 输入以下指令
$gem sources -a https://ruby.taobao.org/
4.验证新源是否替换成功 输入以下指令
$gem sources -l
5.安装 CocoaPods
$sudo gem install cocoa pods
//–––––––––––那么问题来了——没遇到的自动跳过————————————
错误提示1
Error installing cocoapods: activesupport requires Ruby version >= 2.2.2.
解决方案 :
1、安装 RVM baby 版本管理器
$curl -L get.rvm.io | bash -s stable
//________等安装完成 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
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.8]
[ruby-]2.2[.4]
[ruby-]2.3[.0]
[ruby-]2.2-headruby-head
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
- 继续安装 CocoaPods
$sudo gem install cocoa pods
$sudo gem install -n /usr/local/bin cocoapods
$pod setup
- 更新 gem
$sudo gem update --system
- 新建一个项目,名字PodTest(这个随便)
- $ cd 项目路径 (中间有空格,)
cd /Users/lucky/Desktop/PodTest
- 建立Podfile(配置文件)
输入 $pod init
项目中自动生成了Podfile文件,输入具体要安装的第三方(如:pod "AFNetworking", "~> 3.0" 注:单引号)
再输入 $pod install
注意:现在打开项目不是点击 PodTest.xodeproj了,而是点击 PodTest.xcworkspace
为了确定AFNetworking是否支持CocoaPods,可以用CocoaPods的搜索功能验证一下。在终端中输入:
$ pod search AFNetworking
如果安装失败
干货1:安装ruby遇到" Installing Homebrew - Brew Command Not Found"命令找不到解决方案:
Check XCode is installed or not.
$gcc --version
$ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$brew doctor
$brew update.
完成后 执行
$ruby -v
//–––––打印输出–––––––
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
6 继续安装 CocoaPods
$sudo gem install cocoa pods
//______安装成功提示如下______
Done installing documentation for nap, fourflusher, escape, colored, concurrent-ruby, thread_safe, tzinfo, i18n, activesupport, claide, xcodeproj, molinillo, cocoapods-try, netrc, cocoapods-trunk, cocoapods-stats, cocoapods-search, cocoapods-plugins, cocoapods-downloader, cocoapods-deintegrate, fuzzy_match, cocoapods-core, cocoapods after 21 seconds,23 gems installed
$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
干货2:CocoaPods无限卡在Setting up CocoaPods master repo解决方案:
对于初次使用CocoaPods的同学,即使你不使用pod setup命令,在你初次执行pod install命令时,系统也会自动执行pod setup。而由于网络不稳定的原因,不挂VPN是不可能成功执行pod setup的。(我大天朝的墙啊~~~~)
$ pod repo remove master
$ git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/master
$ pod repo update
7 更新 gem
$sudo gem update --system
8 新建工程,并在终端用 cd 指令到文件夹内
$pod search 第三方
9 新建 Podfile 文件
$ touch Podfile
10 编辑 Podfile 文件,并写入要添加的第三方库(cocoapod1.0.1版本Podfile文件的内容格式要求发生了变化,必须指出指出所用第三方库的target)
platform:ios, '8.0'
use_frameworks!个别需要用到它,比如reactiveCocoa
target 'XXXApp' do
pod 'AFNetworking', '~> 2.3.1'<-------第三方
end
11 导入第三方库
$pod install --no-repo-update
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
Failed during: /usr/bin/sudo /usr/bin/xcode-select --install
Requirements installation failed with status: 1.
此时查询Xcode,切换到另一个环境:
$ sudo xcode-select --switch /Library/Developer/CommandLineTools/
