1.安装HomeBrew一直卡住

git fetch origin master:refs/remotes/origin/master --tags --force

2./Users/xxxxx/.rbenv/shims/ruby: line 21: /usr/local/Cellar/rbenv/1.1.1/libexec/rbenv: No such file or directory

解决方案：
安装 rbenv
brew install rbenv

3.升级MacOS ,或者升级Xcode,遇到

/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- xcodeproj (LoadError)

解决方案:
终端执行 sudo gem install xcodeproj

4.长时间未更新CocoaPods、或者升级了Mac OS，导致pod install无效

报错

/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

解决方案：
sudo gem install -n /usr/local/bin cocoapods
这个过程需要时间比较久，需要耐心等待下；
执行完后，再执行 pod install，如果遇到

[!] CDN: trunk Repo update failed - 22 error(s):

在Podfile文件下添加下面，即可

source 'https://github.com/CocoaPods/Specs.git'

5.ReactNative 项目执行npm install,报以gyp错误

gyp: No Xcode or CLT version detected!
gyp ERR! configure error 
gyp ERR! stack Error: `gyp` failed with exit code: 1
gyp ERR! stack     at ChildProcess.onCpExit (/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:345:16)

解决方案

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

6、更新自己维护的CocoaPods的库时，执行‘pod trunk push ZHXIndexView.podspec --allow-warnings ’ 遇到

[!] CDN: trunk Repo update failed - 2 error(s):
CDN: trunk URL couldn't be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/1/e/4/AFOAuth2Client/1.0.0/AFOAuth2Client.podspec.json Response: Couldn't connect to server

3、重新执行pod trunk push 即可。
