安装 cocoapods
1. 安装/更新 gem
看这个就好了 国内镜像官网 https://gems.ruby-china.com/
这里简单列下步骤
$ gem update --system #这里请翻墙一下
$ gem -v
$ gem sources -l
$ gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ #remove的网址应该是上一个结果打印出来的网址
2. 安装 cocoapods
$ gem install cocoapods
3. 添加 podfile 文件
输入
platform :ios, '11.0'
use_frameworks!
target '#这里填自己的项目名' do
# 这里是依赖的库
pod 'Alamofire', '~> 5.0.0-rc.3'
pod 'WCDB.swift'
end
执行 pod install 即可
常见问题及解决方案
错误 1： Permission denied
ERROR: While executing gem ... (Errno::EACCES)
Permission denied
Why 执行何命令导致：gem update --system
Solution 解决办法
$ rvm fix-permissions
$ rvm reinstall 2.5.6
错误 2：cannot load such file
kernel_require.rb:55:in `require':
Why 执行何命令导致：pod install or pod update
solution 解决办法
- 更新 rvm 版本（非必要）
rvm get stable - 删除多余的 ruby 版本，下面的 xxx 是版本号
• 查看 ./rvm/gems 中有几个 ruby 版本
•rvm remove xxx，删除多余的版本
•rvm use xxx设置 ruby 的使用版本
错误 3：GemNotFoundException
can't find gem cocoapods (>= 0.a) with executable pod (Gem::GemNotFoundException)
why 执行何命令导致：pod install
solution 解决方案：
先卸载再安装
$ gem uninstall cocoapods
$ gem install cocoapods
详细过程记录（废话）
- 更新/安装 gem
gem update --system
过了几分钟，我这边跳出来的结果

加上 sudo 试了下，同样的错误
然后在 stackoverflow上找到了这个解决
$ rvm fix-permissions
$ rvm reinstall 2.5.6
当时 gem 安装成功后 pod 也更新成功了
两天后，中间电脑关过一次机，今天又抽风了
- 更新 pod 时报错
rubygems/core_ext/kernel_warn
/Users/joanfen/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- rubygems/core_ext/kernel_warn (LoadError)

from <internal:gem_prelude>:4:in `<internal:gem_prelude>'
执行了
rvm fix-permissions
# 这里的 2.5.6 是 ruby 版本号
rvm reinstall 2.5.6
发现还是不行，于是执行了
rvm info
发现没有设置过默认的 ruby 版本

看了下自己的 .rvm/gems/ 里面有好几个 ruby 版本，于是把除了 2.5.6 的那个版本删掉
rvm remove 版本号
看了下自己的 rvm 版本号也过低，更新rvm版本
rvm get stable
更新后设置 ruby 版本
rvm use 2.5.6
再查看
rvm info
得到信息
ruby-2.5.6:

再次执行

没发现 cocoapods 这就很明显，重新安装了下 cocoapods，这里很诡异，明明前天才安装的 cocoapods，不知道自己做了什么操作搞成这样
gem install cocoapods
再次尝试 pod install
开始 Analyzing dependencies
问题解决
