Cocopods遇到的一些问题

mac电脑 pod install时候遇到的一些问题

===========问题1============================

Mac 系统更新到 macOS Catalina 10.15 之后 发现pos install 报错

-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad

解决：

粗暴点，直接重装

sudo gem install cocoapods

执行后还是报错

ERROR: Could not find a valid gem 'cocoapods' (>= 0) in any repository

-------------------分割线-------------------------------------

输入这段命令行就好了，输入后会执行一堆操作等着就好，然后直接pod install就成功了

sudo gem install cocoapods --source http://rubygems.org

===========问题2============================

cocopads更新库时失败，报错Failed to extract git version from ' git --version ' xcrun: error: invalid active developer path

最近 升级了一下电脑系统 macOSMojave 10.14.1

顺便升级了一下 Xcode Version 10.1 (10B61)

哭了 使用 cocosPods  集成时 报错

Mac:~mac$ pod-versionTraceback(most recent call last):5:from/usr/local/bin/pod:23:in`

'4:from/usr/local/bin/pod:23:in`load'3:from/Users/mac/.rvm/gems/ruby-2.5.1@global/gems/cocoapods-1.5.3/bin/pod:55:in`'2:from/Users/mac/.rvm/rubies/ruby-2.5.1/lib/ruby/gems/2.5.0/gems/cocoapods-1.5.3/lib/cocoapods/command.rb:49:in`run'1:from/Users/mac/.rvm/rubies/ruby-2.5.1/lib/ruby/gems/2.5.0/gems/cocoapods-1.5.3/lib/cocoapods/command.rb:130:in`verify_minimum_git_version!'/Users/mac/.rvm/rubies/ruby-2.5.1/lib/ruby/gems/2.5.0/gems/cocoapods-1.5.3/lib/cocoapods/command.rb:118:in`git_version':Failedto extract git versionfrom`git--version`("xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun\n")(RuntimeError)

分析：

Failed to extract git version from ' git --version ' xcrun: error: invalid active developer path

未能从git—version中提取 git 版本: 错误: 无效的活动开发路径；简单来说就是Git工具不好使了。

通常做法就是打开 terminal 执行 xcode-select --install

但由于我是 macOS 升级 所以这样是不行的，需要到 Git 官网下载 Git 才可以：

https://git-scm.com/download/mac

下载完成后手动安装 git 这样就可以解决了 ！

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

！！！以上方法网慢始终下载失败，最后在终端直接打这个命令执行完安装就ok了

命令行执行: xcode-select --install解决问题 . 重要的话说三遍!!!

问题描述

[!] Error installing Masonry

fatal: unable to access 'https://github.com/cloudkite/Masonry.git/': Failed to connect to github.com port 443: Operation timed out

试了各种方法都没有效果

只有下边这个方法解决了该问题

需要在finder 前往文件夹 打开 /etc/hosts 文件，然后复制到本地

打开浏览器放入该链接

http://tool.chinaz.com/dns/?type=1&host=github.com&ip=

aaaaaa

然后复制到 hosts文件里 后面 加上 github.com 如下

bbbbbb

保存 然后 复制文件到 etc/hosts 覆盖掉 

重新打开终端 cd到当前目录 执行 pod install

==========问题4============================

pod安装某个三方库时候，失败，看原因貌似时依赖某个指定版本

解决方法：删除.workspace和.lock文件，重新执行podinstall
