pod安装和制定版本

《cocoapods更新某个版本》

报错

执行pod setup后，等很久还是失败了

$ pod setup

Setting up CocoaPods master repo
  $ /usr/bin/git clone https://github.com/CocoaPods/Specs.git master --progress
  Cloning into 'master'...

解决

1. 官网下载Specs，https://github.com/CocoaPods/Specs.git
2. 解压Specs-master.zip，把解压后的Specs-master文件夹里面所有文件放到.cocoapods/repos/master/里面

AlgoliaSearch.yml
Gemfile
README.md
Specs
CocoaPods-version.yml Gemfile.lock
Scripts
netlify.toml

3. 进入maser目录(没有就自己建)

$ cd .cocoapods/repos/master/

4. git初始化

$ git init

5. 关联仓库

$ git remote add origin https://github.com/CocoaPods/Specs

6. 查看repo是否正常

$ pod repo

master
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
- Type: git (unknown)
- URL:  https://github.com/CocoaPods/Specs
- Path: /Users/weever/.cocoapods/repos/master

1 repo

7. 测试下 pod search和pod install，首次比较慢

$ pod search AFNetwork

Creating search index for spec repo 'master'.. Done!
