# 2022年最新Mac OS 最新安装cocopods 安装超级快速为您节省大量时间与精力 30分钟搞定的教程(需要注意的是电脑一次没有安装过cocopods,如果安装过不建议使用这个方式安装)已经_mac 安装cocoapods 1.12.0

cocopods安装地址
安装方法
1.运行脚本安装rvm

sh /Users/xxx/Documents/rvm_install.sh
1

注意 sh 文件没有在电脑打开权限需要输入以下命令方可使用

cd /Users/xxx/Documents/安装\ cocopods\xxx
chmod -R 777 rvm_install.sh
1
2

需要注意的是cd到存放sh外层的文件夹就可以了,然后输入打开权限命令即可
使用以下命令检测是否安装成功

rvm -v 
1

出现以下内容就安装成功了

rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]
1

2.运行脚本安装homebrew
与安装rvm方式相同
homebrew无论是脚本安装还是命令安装都不会出问题,不过脚本安装的不可以使用它安装别的软件这个需要注意
命令安装国内镜像,国外镜像安装不了就不拿出来了

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
1

检测是否安装成功命令

1.查看Homebrew命令：brew help
2.安装任意包：brew install ，eg：brew install node
3.卸载任意包：brew uninstall ，eg：brew uninstall git
4.查询可用包：brew search 
5.查询已安装包列表：brew list
6.查看任意包信息：brew info 
7.更新Homebrew：brew update
8.Homebrew帮助信息：brew -h
8.查看brew版本：brew -v
10.更新brew版本：brew update
11.整理重复语句：open ~/.zshrc -e、open ~/.bash_profile -e
12.用浏览器打开：brew home

3.安装rvm指定版本,需要先安装rvm才可以使用此命令(使用脚本安装过的)

rvm install 3.0.0
1

原因:因为自2021年以后安装cocopods的电脑均要使用rvm版本号2.6.0以上否则无法安装cocopods
如果没有使用脚本安装则直接使用第三个命令安装即可,安装后无需设置默认版本
一、切换rvm版本

rvm use 3.0.0
1

二、设置默认rvm版本

rvm use 3.0.0 --default
1

三、如遇到rvm无法设置默认版本号问题则将默认的rvm全部移除重新使用以下命令安装默认版本

curl -sSL https://get.rvm.io | bash -s stable --ruby
1

四、彻底卸载rvm

rvm  implode
1

五、查看版本号

rvm -v
1

六、查看安装的rvm列表

rvm list
1

4.使用安装网址中安装cocopods命令即可(也就是从网页中的第7步骤开始运行命令就可以了)

此方法省略了一些比较复杂的程序,因为使用安装命令安装homebrew和rvm时间比较长而且安装后还容易出错 这样安装后不会有任何问题
不过需要注意的是这种安装homebrew的方法会对使用 homebrew 安装别的终端软件造成影响,也就是有的软件无法继续使用homebrew安装了例如:

brew install freetype
1

这个软件就无法安装上
所以使用这个方式安装cocopods还是需要考虑清楚的

附带上脚本文件

1.rvm脚本,复制以下脚本代码到一个文件中并命名为.sh后缀的文件,需要注意的是这个创建的文件必须是干净的文件,也就是说不可以使用mac电脑上的文本编辑软件来创建脚本文件,可以使用wps或者pages文稿软件创建.sh文件
例如我的命名:rvm_install.sh

#!/usr/bin/env bash

shopt -s extglob
set -o errtrace
set -o errexit
set -o pipefail

Usage

  rvm-installer [options] [action]

Options

  [[--]version] <version>

    The version or tag to install. Valid values are:

      latest         - The latest tagged version.
      latest-minor   - The latest minor version of the current major version.
      latest-<x>     - The latest minor version of version x.
      latest-<x>.<y> - The latest patch version of version x.y.
      <x>.<y>.<z>    - Major version x, minor version y and patch z.

  [--]branch <branch>

    The name of the branch from which RVM is installed. This option can be used
    with the following formats for <branch>:

      <account>/

        If account is rvm or mpapis, installs from one of the following:

          https://github.com/rvm/rvm/archive/master.tar.gz
          https://bitbucket.org/mpapis/rvm/get/master.tar.gz

       Otherwise, installs from:

         https://github.com/<account>/rvm/archive/master.tar.gz

      <account>/<branch>

        If account is rvm or mpapis, installs from one of the following:

          https://github.com/rvm/rvm/archive/<branch>.tar.gz
          https://bitbucket.org/mpapis/rvm/get/<branch>.tar.gz

        Otherwise, installs from:

          https://github.com/<account>/rvm/archive/<branch>.tar.gz

      [/]<branch>

        Installs the branch from one of the following:

          https://github.com/rvm/rvm/archive/<branch>.tar.gz
          https://bitbucket.org/mpapis/rvm/get/<branch>.tar.gz

      [--]source <source>

        Defines the repository from which RVM is retrieved and installed in the format:

          <domain>/<account>/<repo>

        Where:

          <domain>  - Is bitbucket.org, github.com or a github enterprise site serving
                      an RVM repository.
          <account> - Is the user account in which the RVM repository resides.
          <repo>    - Is the name of the RVM repository.

        Note that when using the [--]source option, one should only use the [/]branch format
        with the [--]branch option. Failure to do so will result in undefined behavior.

      --trace

        Provides debug logging for the installation script.
Actions

  master - Installs RVM from the master branch at rvm/rvm on github or mpapis/rvm
           on bitbucket.org.
  stable - Installs RVM from the stable branch a rvm/rvm on github or mpapis/rvm
           on bitbucket.org.
  help   - Displays this output.

                初步介绍几个brew命令

        本地软件库列表：brew ls
        查找软件：brew search google（其中google替换为要查找的软件关键字）
        查看brew版本：brew -v  更新brew版本：brew update

        Formulae（方案库 例如python）
        安装方案库：brew install curl（其中curl替换为要安装的软件库名称）
        卸载方案库：brew uninstall curl（其中curl替换为要卸载的软件库名称）

        Casks   （界面软件 例如谷歌浏览器）
        安装软件：brew cask install visual-studio-code（其中visual-studio-code替换为安装的软件名字，例如google-chrome）
        卸载软件：brew cask uninstall visual-studio-code（其中visual-studio-code替换为要卸载的软件名字，例如google-chrome）

        查找命令安装的位置：which brew（brew可以换成任何命令，包括brew安装的）
\033[1;32m
现在可以输入命令open ~/.zshrc 或者 open ~/.bash_profile 整理一下重复的语句(运行 echo \$SHELL 可以查看应该打开那一个文件修改)
