Cocoapods的安装报错 - Error installing pods:activesupport requires Ruby version >=2.2.2
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
如果打印:
…… ruby-2.2.2 - #validate archive ruby-2.2.2 - #extract ruby-2.2.2 - #validate binary ruby-2.2.2 - #setup ruby-2.2.2 - #gemset created /Users/abc/.rvm/gems/ruby-2.2.2@global ruby-2.2.2 - #importing gemset /Users/abc/.rvm/gemsets/global.gems.............................. ruby-2.2.2 - #generating global wrappers........ ruby-2.2.2 - #gemset created /Users/abc/.rvm/gems/ruby-2.2.2 ruby-2.2.2 - #importing gemsetfile /Users/abc/.rvm/gemsets/default.gems evaluated to empty gem list ruby-2.2.2 - #generating default wrappers........ Updating certificates in '/etc/openssl/cert.pem'. mkdir: /etc/openssl: Permission denied mkdir -p "/etc/openssl" failed, retrying with sudo LiuWenqiang password required for 'mkdir -p /etc/openssl': and sudo mkdir worked
则说明安装成功了
打印代码:
Done with Command Line Tools (OS X 10.11) for Xcode Done. ==> /usr/bin/sudo /bin/rm -f /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress ==> Installing the Command Line Tools (expect a GUI popup): ==> /usr/bin/sudo /usr/bin/xcode-select --install 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.
4. 继续安装 CocoaPods
$sudo gem install cocoa pods $sudo gem install -n /usr/local/bin cocoapods $pod setup
5. 更新 gem
$sudo gem update --system
6. 新建一个项目,名字PodTest
7. $ cd 项目路径 (中间有空格,)
cd /Users/lucky/Desktop/PodTest
8. 建立Podfile(配置文件)
$vim Podfile
键盘输入" i "进入编辑模式,输入
platform :ios, '7.0' pod 'MBProgressHUD', '~> 0.8’ (之前的,我的电脑上已经无效了,报错: [!] The dependency `MBProgressHUD (~> 0.8)` is not used in any concrete target.) (现在使用:MyApp 替换成自己的项目名) target 'MyApp' do pod 'AFNetworking', '2.6' pod 'ORStackView', '3.0' end
然后
按Esc,并且输入“ :”号进入vim命令模式,然后在冒号后边输入wq
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 第三方库
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/ Password: $ git usage: git [--version] [--help] [-C <path>] [-c name=value] [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path] [-p | --paginate | --no-pager] [--no-replace-objects] [--bare] [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>] <command> [<args>]
