卸载

1.卸载Cocoapods

sudo gem uninstall cocoapods

2.查看本地安装过的cocopods相关东西

gem list --local | grep cocoapods

显示如下:

cocoapods (1.0.1)

cocoapods-core (1.0.1)

cocoapods-deintegrate (1.0.1)

cocoapods-downloader (1.1.1)

cocoapods-plugins (1.0.0)

cocoapods-search (1.0.0)

cocoapods-stats (1.0.0)

cocoapods-trunk (1.0.0)

cocoapods-try (1.1.0)

然后使用命令逐个删除

sudo gem uninstall cocoapods-core

注:如果出现root用户没有/user/bin权限,那是由于系统启用了SIP（System Integerity Protection）导致root用户也没有修改权限，所以我们需要屏蔽掉这个功能

1.重启电脑

2.command + R 进入recover模式

3.点击最上方菜单使用工具，选择终端

4.运行命令csrutil disable

5.重新启动电脑

安装

1.查看当前Ruby版本

ruby -v

2.升级Ruby环境，首先需要安装rvm

curl -L get.rvm.io | bash -s stable

source ~/.bashrc

source ~/.bash_profile

3.查看rvm版本

rvm -v

结果: rvm 1.29.9 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

4.安装rvm(版本可以通过rvm list查看可以安装的rvm的版本)

rvm install 2.5.1

注: 如果没有安装homebrew可能会报错

安装homebrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安装homebrew的时候可能会出现这样的错误:

报错一: error: RPC failed; curl 56 LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 60

fatal: the remote end hung up unexpectedly

fatal: early EOF

fatal: index-pack failed

Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core failed!

Failed during: /usr/local/bin/brew update --force

这里网上找了很多方法试了一下,最后,更换清华大学的homebrew的镜像源:

git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git

brew update

报错二: Error: Another active Homebrew update process is already in progress.

Please wait for it to finish or terminate it to continue.

解决方法:

rm -rf /usr/local/var/homebrew/locks

然后重新执行 rvm install 2.5.1

5.更换源

查看源是什么 gem sources -l

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

更换为 gem sources --add https://gems.ruby-china.com/

注:如果安装了多个Xcode使用下面的命令选择

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

6.安装cocoapod

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

7.安装本地库

pod setup
