前序安装步骤参考这个文章即可，简单明了。 # CocoaPods安装方法-2023.09.15
我讲几个我安装过程中遇到的问题:
不管报什么错误，先去严格检查这三个东西安装好没有！！！
不管报什么错误，先去严格检查这三个东西安装好没有！！！
不管报什么错误，先去严格检查这三个东西安装好没有！！！
1、Xcode
2、Command Line Tools for Xcode
3、Homebrew
可能的报错情况：
1、执行➜ rvm install ruby-3.2.2 报错了。。。
a.首先确保homebrew update 和 homebrew doctor 都成功了,执行提示这个了Your system is ready to brew.，没有就在回去安装.
另外最新homebrew 安装完了还要执行两个命令：
echo "eval $(/opt/homebrew/bin/brew shellenv)" >> ~/.zprofile
eval $(/opt/homebrew/bin/brew shellenv)
b.去xcode -> setting-> locations检查看Command Line Tools有没有安装，路径对不对！！
前面都没问题了，如果还报错误，可能的错误信息如下。
报错类似如下：Error running '__rvm_make -j8' 或者openssl 错误
Searching for binary rubies, this might take some time.
DNo binary rubies available for: osx/14.0/arm64/ruby-3.2.2.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

There has been an error while running make. Halting the installation.
执行以下命令修复：
rvm reinstall 3.2.2 --with-openssl-dir=$(brew --prefix openssl) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --disable-dtrace --disable-docs
2、都安装成功后，执行pod 命令时报错类似：
undefined method `deprecator' for ActiveSupport:Module ( **NoMethodError** )
/Users/eddie/.rvm/rubies/ruby-3.2.2/lib/ruby/gems/3.2.0/gems/activesupport-7.1.0/lib/active_support/core_ext/array/conversions.rb:108:in
<class:Array>': **undefined methoddeprecator' for ActiveSupport:Module (** NoMethodError )
deprecate to_default_s: :to_s, deprecator: ActiveSupport.deprecator ^^^^^^^^^^^
Did you mean? deprecate_constant
解决方法：
我这里使用的是1.13.0 pod版本！！！
先执行命令：
sudo gem uninstall activesupport
提示：
You have requested to uninstall the gem:
activesupport-7.1.0
cocoapods-core-1.13.0 depends on activesupport (>= 5.0, < 8)
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN] y
Successfully uninstalled activesupport-7.1.0
然后再执行这个命令：
sudo gem install activesupport -v 7.0.8
提示：
Successfully installed activesupport-7.0.8
Parsing documentation for activesupport-7.0.8
Installing ri documentation for activesupport-7.0.8
Done installing documentation for activesupport after 0 seconds
1 gem installed
在试试pod 命令应该就可以了。。。
PS：暂时就记得这几个问题了，其他想起来再补充。 Ruby一定要安装最新版本哈。
升级xcode到15可能出现的错误
出现一堆libc++ abi的错误，跑不起来.
解决办法：
在other linker flags里面添加-ld64。
出现：SDK does not contain 'libarclite' at the path '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a'; try increasing the minimum deployment target
解决办法：
按说明，去增加对应库的iOS Deployment Target 版本号，现在最低都在iOS12以上了吧，不是的申请往高调吧，低了没用，还麻烦😄
