安裝 cocoapods
1. 安裝/更新 gem
看這個就好了 國內(nèi)鏡像官網(wǎng) https://gems.ruby-china.com/
這里簡單列下步驟
$ gem update --system #這里請翻墻一下
$ gem -v
$ gem sources -l
$ gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ #remove的網(wǎng)址應(yīng)該是上一個結(jié)果打印出來的網(wǎng)址
2. 安裝 cocoapods
$ gem install cocoapods
3. 添加 podfile 文件
輸入
platform :ios, '11.0'
use_frameworks!
target '#這里填自己的項目名' do
# 這里是依賴的庫
pod 'Alamofire', '~> 5.0.0-rc.3'
pod 'WCDB.swift'
end
執(zhí)行 pod install 即可
常見問題及解決方案
錯誤 1： Permission denied
ERROR: While executing gem ... (Errno::EACCES)
Permission denied
Why 執(zhí)行何命令導(dǎo)致：gem update --system
Solution 解決辦法
$ rvm fix-permissions
$ rvm reinstall 2.5.6
錯誤 2：cannot load such file
kernel_require.rb:55:in `require':
Why 執(zhí)行何命令導(dǎo)致：pod install or pod update
solution 解決辦法
- 更新 rvm 版本（非必要）
rvm get stable - 刪除多余的 ruby 版本，下面的 xxx 是版本號
? 查看 ./rvm/gems 中有幾個 ruby 版本
?rvm remove xxx，刪除多余的版本
?rvm use xxx設(shè)置 ruby 的使用版本
錯誤 3：GemNotFoundException
can't find gem cocoapods (>= 0.a) with executable pod (Gem::GemNotFoundException)
why 執(zhí)行何命令導(dǎo)致：pod install
solution 解決方案：
先卸載再安裝
$ gem uninstall cocoapods
$ gem install cocoapods
詳細(xì)過程記錄（廢話）
- 更新/安裝 gem
gem update --system
過了幾分鐘，我這邊跳出來的結(jié)果

加上 sudo 試了下，同樣的錯誤
然后在 stackoverflow上找到了這個解決
$ rvm fix-permissions
$ rvm reinstall 2.5.6
當(dāng)時 gem 安裝成功后 pod 也更新成功了
兩天后，中間電腦關(guān)過一次機(jī)，今天又抽風(fēng)了
- 更新 pod 時報錯

執(zhí)行了
rvm fix-permissions
# 這里的 2.5.6 是 ruby 版本號
rvm reinstall 2.5.6
發(fā)現(xiàn)還是不行，于是執(zhí)行了
rvm info
發(fā)現(xiàn)沒有設(shè)置過默認(rèn)的 ruby 版本

看了下自己的 .rvm/gems/ 里面有好幾個 ruby 版本，于是把除了 2.5.6 的那個版本刪掉
rvm remove 版本號
看了下自己的 rvm 版本號也過低，更新rvm版本
rvm get stable
更新后設(shè)置 ruby 版本
rvm use 2.5.6
再查看
rvm info
得到信息
ruby-2.5.6:

沒發(fā)現(xiàn) cocoapods 這就很明顯，重新安裝了下 cocoapods，這里很詭異，明明前天才安裝的 cocoapods，不知道自己做了什么操作搞成這樣
gem install cocoapods
再次嘗試 pod install
開始 Analyzing dependencies
問題解決
