Mac下 cocoapods重装,及pod command 找不到解决

这里我就长话短说,直接上代码

1. 卸载已有的cocoapods

sudo gem uninstall cocoapods

2. 查看本地安装过的cocopods相关东西

gem list --local | grep cocoapods

3. 删除上述文件

sudo gem uninstall cocoapods-xxx

4. 查看Ruby环境

gem sources -l
若不合适,即修改
gem source -r https://rubygems.org/
gem source -a https://ruby.taobao.org/ (已停用)
gem sources -a https://gems.ruby-china.org/ (用这个)

5. 安装cocoapods

sudo gem install cocoapods
或者 sudo gem install -n /usr/local/bin cocoapods --re

如果遇到
Unable to resolve dependencies: cocoapods requires cocoapods-core (= 0.35.0), claide (~> 0.7.0), xcodeproj (~> 0.20.2), cocoapods-downloader (~> 0.8.0)
则需要重新更新gem
sudo gem update --system

pod setup
所有的项目的 Podspec 文件都托管在https://github.com/CocoaPods/Specs。第一次执行pod setup时，CocoaPods 会将这些podspec索引文件更新到本地的~/.cocoapods/目录下，这个索引文件比较大.
为了更快的下载这些索引文件,我们更换源
$ git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
$ pod repo update
$ pod update

如果遇到
[!] Failed to connect to GitHub to update the CocoaPods/Specs specs repo - Please check if you are offline, or that GitHub is down
我建议在 ~/.cocoapods/repos/master 的子目录 将Specs 文件名改为master,重新pod setup 等待一段时间,可能就会成功

6. 查看pod 版本

pod --version
1.3.1

7. 此时如果出现pod command找不到

将pod 添加到环境变量中 /usr/local/bin

具体操作可参考这篇文章

8. cocoapods 使用

1.进入到项目根目录下，生成Podefile文件
$pod init

2.填写对应的信息

3.下载第三方库
pod install

Podfile 基本格式

platform :ios, '9.0'

target '集成cocoapods' do
    pod 'AFNetworking'
    pod 'MJExtension'
end
