Cocoapods configuration installation process

Record the development of Flutter to configure the IOS environment.

First install  the XCode  development tool, which will help you install the development package required for the Unix environment.

Then install Homebrew

Installing CocoaPods requires a Ruby environment, so first check the version of the Ruby environment!

first step:

The first thing to check is that your Mac has rvm installed. Open the terminal and enter the command rvm -v

If command not found is displayed. Indicates that it is not followed. Then proceed to the second step. If installed, skip to step 3 to start.

Step two:

terminal input

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

***May prompt Failed to connect to raw.githubusercontent.com port 443: Connection refused

The network environment is not good, so find other ways by yourself. I'm skipping it here.

 Picture after successful installation:

After installation, exit the terminal, and then enter rvm -v (the terminal does not exit, it always displays the state of the first step)

rvm -v

The picture of rvm -v after the second step of installation is successful :

 third step:

List all ruby ​​versions in the specified source

rvm list known

the fourth step:

install the latest

rvm install 3.0.0

Installed pictures 

the fifth step:

Check the installed version

 rvm list

Step six:

Check the ruby ​​source

gem sources -l

If the ruby ​​source is not this https://gems.ruby-china.com/ 
use:

6.1 Remove the ruby ​​source

gem sources --remove https://rubygems.org/

6.2 Then add

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

6.3 

gem sources -l 

gem sources -l Check again if it is https://gems.ruby-china.com/ 

Step seven:

安装cocoapods （CocoaPods Guides - Getting Started）

or
