前言

最近在使用pod，发现直接报错一大堆(ノへ￣、)捂脸，在此整理一下2019年最新版本的安装以及遇到的问题

安装步骤

如果你想直接卸载，用下面命令行：

#卸载
sudo gem uninstall cocoapods

使用这个命令，如果你mac中装了很多pod 它会出现一个列表，让你选择，建议直接选择全部删除。

安装

pod安装其实很简单，就2个东西，一个是源，一个是ruby 然后就没了，看网上巴拉巴拉一大堆，呵呵哒
1.安装源

在我的mac 10.14.5 系统我下载淘宝的https://ruby.taobao.org/这个，一直报错，我使用的是https://gems.ruby-china.com/

gem sources --remove https://rubygems.org/
gem sources -a https://gems.ruby-china.com/

2.ruby 环境
当你在更新mac系统的时候，ruby版本也会跟随着升级,命令行直接查看，ruby是2.3.7的，直接使用就可以了

lengwujudeMacBook-Pro:~ sfyh$ ruby --version
ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin18]
lengwujudeMacBook-Pro:~ sfyh$

上面步骤好了之后，

lengwujudeMacBook-Pro:~ sfyh$ sudo gem install cocoapods
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /usr/bin directory.

这个地方报错了，看下错误信息是因为没权限，sudo安装，

Successfully installed xcodeproj-1.12.0

我以为装好了，然后pod看看，然后就蒙了。。

lengwujudeMacBook-Pro:~ sfyh$ pod --version
Ignoring ffi-1.9.25 because its extensions are not built.  Try: gem pristine ffi --version 1.9.25

    from /usr/local/bin/pod:23:in `load'
    from /usr/local/bin/pod:23:in `<main>'

看上面的错误信息，它给了提示要执行gem pristine ffi --version 1.9.25，然后我试了下

lengwujudeMacBook-Pro:~ sfyh$ gem pristine ffi --version 1.9.25
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

没权限，sudo一下，报错了，信息如下：

lengwujudeMacBook-Pro:~ sfyh$ sudo gem pristine ffi --version 1.9.25
Password:

Results logged to /Library/Ruby/Gems/2.3.0/extensions/universal-darwin-18/2.3.0/ffi-1.9.25/gem_make.out

上面这个报错，链接找不到了，我把解决报错的命令放下面：

lengwujudeMacBook-Pro:~ sfyh$ gem install bundler && rbenv rehash
Fetching: bundler-2.0.2.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

然后又会报错 You don't have write permissions for the /Library/Ruby/Gems/2.3.0 ，这个问题可以看下点我

继续：

lengwujudeMacBook-Pro:~ sfyh$ sudo gem install cocoapods --user-install
WARNING:  You don't have /Users/sfyh/.gem/ruby/2.3.0/bin in your PATH,
      gem executables will not run.
Successfully installed cocoapods-1.7.5
Parsing documentation for cocoapods-1.7.5
Installing ri documentation for cocoapods-1.7.5
Done installing documentation for cocoapods after 3 seconds

到这个地方已经安装成功了，然后pod看下版本，

lengwujudeMacBook-Pro:~ sfyh$ pod --version
/Users/sfyh/.gem/ruby/2.3.0/gems/cocoapods-1.7.5/lib/cocoapods/command.rb:118:in `git_version': Failed to extract git version from `git --version` ("xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun\n") (RuntimeError)

    from /usr/local/bin/pod:23:in `load'
    from /usr/local/bin/pod:23:in `<main>'
lengwujudeMacBook-Pro:~ sfyh

看上面的报错是xcrun的问题，就是Xcode没有设置路径，

lengwujudeMacBook-Pro:~ sfyh$ xcrun
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
lengwujudeMacBook-Pro:~ sfyh$ xcrun --version
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

设置一下，再次pod 看下

lengwujudeMacBook-Pro:~ sfyh$ xcrun --version
xcrun version 47.
lengwujudeMacBook-Pro:~ sfyh$ pod --version
1.7.5

终于好了😂😂😂😂😂

还有一个问题纪录一下，报错信息如下：

ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.

解决方法如下：

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

更新于 2021年1月20号

报错信息如下：

上面报错信息说的是ruby 路径有问题，解放方式如下：
1.先确认Ruby的版本
2.确认Ruby所在的路径

cuilinhaodeMacBook-Pro:~ cuilinhao$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]
cuilinhaodeMacBook-Pro:~ cuilinhao$ which ruby
/usr/bin/ruby
cuilinhaodeMacBook-Pro:~ cuilinhao$ brew install ruby

你可以用Homebrew安装最新的Ruby
ps：遇到一个奇葩的问题，就是安装Homebrew时，一直安装失败，你要先尝试打开这个链接看下是不是网络问题，如果一直打不开，那就gg了，那肿么办呢
放大招了嘿嘿
一行脚本搞定

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

你可以试试，如果还有问题看下这个文章

GO ON <<

安装最新的Ruby 然后查看Ruby的位置

cuilinhaodeMacBook-Pro:~ cuilinhao$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]
cuilinhaodeMacBook-Pro:~ cuilinhao$ which ruby
/usr/bin/ruby
cuilinhaodeMacBook-Pro:~ cuilinhao$ brew install ruby

重置PATH的，脚本如下：

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.bash_profile
$ echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.bash_profile
$ echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.bash_profile

$ source ~/.bash_profile

终端显示如下：

cuilinhaodeMacBook-Pro:~ cuilinhao$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/cuilinhao/.bash_profile
cuilinhaodeMacBook-Pro:~ cuilinhao$ echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.bash_profile
cuilinhaodeMacBook-Pro:~ cuilinhao$ echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.bash_profile
cuilinhaodeMacBook-Pro:~ cuilinhao$ source ~/.bash_profile
cuilinhaodeMacBook-Pro:~ cuilinhao$ ruby -v
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-darwin20]
cuilinhaodeMacBook-Pro:~ cuilinhao$ which ruby

cuilinhaodeMacBook-Pro:~ cuilinhao$ sudo gem install -n /usr/local/bin cocoapods

按照步骤一步一步安装就OK
