第三方库使用CocoaPods引入 问题汇总

updating......

- pod install

问题1：[!] Unable to find a specification for 'xxx'（找不到第三方框架）

  • pod repo update 更新一下repo，更新完成之后即可解决

问题2：Specs satisfying the ' XXXPods/Masonry (~> 1.0.15) ' dependency were found, but they required a higher minimum deployment target.

  • 检查PodFile文件里platform系统版本号，一般是因为版本低于依赖第三方库所支持的最低系统版本
  • 例如 platform :ios, '9.0'

- pod setup

问题1：[!] Unable to add a source with url 'https://github.com/CocoaPods/Specs.git' named 'master'. You can try adding it manually in '~/.cocoapods/repos' or via 'pod repo add'.

问题2：error: RPC failed; curl 18 transfer closed with outstanding read data remaining

fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

  • 网络问题，最直接的办法.....连热点操作.....
  • 也可以进入.cocoapods/repos/目录下直接克隆（也依赖网络）
    git clone https://github.com/CocoaPods/Specs.git

查看本地仓库

  • cd ~/.cocoapods
  • cd repos/
  • cd ls

问题：升级ruby后：find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException)

  • ruby路径问题，需要重新安装cocoapods
  • sudo gem uninstall cocoapods
    -gem install cocoapods
  • pod install
  • 紧接着可能出现以下问题

问题：

   CocoaPods : 1.3.1

cocoapods对应版本依赖，可以查看： https://rubygems.org/gems/cocoapods/versions/1.3.1
相关问题讨论见：https://github.com/CocoaPods/CocoaPods/issues/7765
#导致的原因主要是：
gem 2.7.7 can not run cocoapods 1.3.x . 1.4.x
you should install rubygem in 2.7.6-意思是要把rubygems回退到2.7.6

  • gem install rubygems-update -v 2.7.6
  • update_rubygems

问题：如果上一步回退rubygems遇到问题：

ERROR: Could not find a valid gem 'rubygems-update' (= 2.7.6) in any repository

ERROR: Possible alternatives: rubygems-update

就是国内网络的问题
查看安装源gem sources -l
如果安装源之前设置过阿里云(http://rubygems-china.oss.aliyuncs.com)或者其他,镜像没有更新新的版本，就会报错找不到对应版本信息。
可尝试直接添加一个安装源：https://rubygems.org/
gem sources -a https://rubygems.org/
然后 :) 连着手机热点跑命令gem install ruby gems-update -v 2.7.6和update_rubygems
当看到以下信息时，说明成功了

bogon:shell liqi$ gem install rubygems-update -v 2.7.6
Fetching: rubygems-update-2.7.6.gem (100%)
Successfully installed rubygems-update-2.7.6

bogon:shell liqi$ update_rubygems
Bundler 1.16.1 installed
RubyGems 2.7.6 installed
Regenerating binstubs

Installing ri documentation for rubygems-2.7.6

------------------------------------------------------------------------------

RubyGems installed the following executables:
    /Users/liqi/.rvm/rubies/ruby-2.4.4/bin/gem
    /Users/liqi/.rvm/rubies/ruby-2.4.4/bin/bundle

Ruby Interactive (ri) documentation was installed. ri is kind of like man 
pages for Ruby libraries. You may access it like this:
  ri Classname
  ri Classname.class_method
  ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.

回退成功后，再执行命令：pod install，不出意外应该可以成功了。

问题：pod lib lint相关

ERROR: Could not find a valid gem 'rubygems-update' (= 2.7.6) in any repository

ERROR: Possible alternatives: rubygems-update
