Unable to add a source with url https://github.com/CocoaPods/Specs.git named cocoapods.
错误场景
使用pod install下载依赖时，出现以下错误
Cloning spec repo `cocoapods` from `https://github.com/CocoaPods/Specs.git` [!] Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `cocoapods`. You can try adding it manually in `/Users/ado/.cocoapods/repos` or via `pod repo add`.
解决方法
这是因为cocoapods的源码在github，国内有时候访问不是很稳定，所以我们可以使用国内镜像源来解决。以下使用清华大学的镜像
$ cd ~/.cocoapods/repos $ pod repo remove master $ git clone https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git master
然后在自己项目的podfile文件的第一行替换成以下代码
source 'https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git'
最后使用pod install即可。
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers
错误场景
朋友mac重装了catalina 10.15.5，使用gem install cocoapods安装cocoapods时出现以下错误。

解决方法
经过网上查询发现是因为从10.15开始，很多目录结构变了，这样会导致编译一些开发库时导致找不到头文件，而macOS_SDK_headers_for_macOS这个文件在10.15之后是没有的，所以这里我们不使用系统自带的ruby来安装cocoapods即可。
使用rvm来安装新版本的ruby，然后再安装cocoapods。
安装rvm
# 安装 curl -sSL https://get.rvm.io | bash -s stable # 刷新环境 source ~/.bash_profile
查询rvm版本验证是否安装成功
rvm -v
安装ruby
rvm install 2.7.4
查看ruby是否安装成功
ruby -v #下面出现版本号代表成功
安装cocoapods
# 如果要指定安装版本，最后加上-v 版本号 sudo gem install -n /usr/local/bin cocoapods -v 1.9.4
验证是否安装成功
pod --version #出现版本号代表成功
requirements_osx_brew_libs_install
错误场景
使用rvm安装ruby时出现以下错误
Error running 'requirements_osx_brew_libs_install autoconf automake libtool pkg-config coreutils libyaml libksba readline zlib openssl@1.1', please read /Users/ado/.rvm/log/1626011972_ruby-2.7.1/package_install_autoconf_automake_libtool_pkg-config_coreutils_libyaml_libksba_readline_zlib_openssl@1.1.log Requirements installation failed with status: 1.
解决方法
打开上面报错提示的log文件，发现是homebrew超过的问题。所以只需要将homebrew的源改成国内镜像源即可。这里我们使用中科大的镜像
替换git
cd "$(brew --repo)" git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
替换core
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
替换Bottles
# 使用echo $SHELL 查看自己的系统是bash还是zsh # bash的方式 echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile source ~/.bash_profile # zsh的方式 echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc source ~/.zshrc
最后再使用rvm install 版本号 就可以正常安装ruby了。
