Cocoapods installation in 2021

Text

I installed it many times CocoaPod, I have encountered all kinds of annoying problems , It also makes me learn a lot from the constant exploration , To sum up , For your study , The following process has been tested by my new machine , A smooth journey without any mistakes ( Please strictly follow the following methods ), If the network is not good, the download may be interrupted and an error may occur , Just execute the command again .

CocoaPods brief introduction :

CocoaPods It's a use. Ruby Written 、 Responsible for managing the iOS Tools of the third party open source library in the project ,CocoaPods What we can focus on 、 Unified management of third-party open source libraries , Save us time setting up and updating third-party open source libraries .

CocoaPods install :

Now the installation begins CocoaPods, There may be a blank space in the middle of the command , It is recommended to copy and paste directly ;

because Mac The computer comes with Ruby Environmental Science , We just need to open the terminal and start . But because by default we mac System native Ruby The environment version is relatively low （ Probably 2.0.0 Or other higher versions ）, But now install CocoaPods need 2.2.2 Version and above , So we will upgrade directly regardless of the three seven twenty-one ruby.

Open the terminal ：>_

1、 View the current Ruby edition

 

ruby -v

2、 upgrade Ruby Environmental Science , Installation is required first rvm（ The first step is to download something and wait about two minutes ）

 

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

source ~/.bashrc

source ~/.bash_profile

3、 see rvm edition

 

rvm -v 

It is shown as follows ( Or other versions )

 

rvm 1.29.3 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

4、 List ruby Installable version information

 

rvm list known

It is shown as follows

 

# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.10]
[ruby-]2.2[.10]
[ruby-]2.3[.7]
[ruby-]2.4[.4]
[ruby-]2.5[.1] 
.....
[ruby-]2.6[.3]  //  That's the point   That's the point   That's the point 
[ruby-]2.7[.0-preview1]   //  The beta 
ruby-head
.....

5、 To install a ruby edition （ So here's what I chose 2.5.1 edition , Of course, you can choose other ）

 

rvm install 2.6.3
//  Be careful : Press twice during installation  Enter  key ,  After the second press, you need to enter the computer access password ( invisible , Just type in );
//  If your computer is not installed Xcode and Command Line Tools for Xcode as well as Homebrew  Will automatically download and install , It is recommended to install these three in advance .

Many friends here will encounter errors , Most of them are not installed Homebrew cause , So it's better to install it in advance

 

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

6、 Set to default version

 

rvm use 2.6.3 --default

7、 Replace source

 

sudo gem update --system

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

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

8、 To verify your Ruby Mirroring is and only ruby-china, Execute the following command to view

 

gem sources -l

If the following results are correct , If there are other problems, please solve them by Baidu

 

*** CURRENT SOURCES ***

https://gems.ruby-china.com/

9、 At this time, the installation started CocoaPods

 

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

10、 If more than one is installed Xcode Use the following command to select （ Generally, you need to select the nearest Xcode edition ）

 

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

11、 Install local libraries

 

pod setup

12、 After executing the above order

 

Setting up CocoaPods master repo
  $ /usr/bin/git clone https://github.com/CocoaPods/Specs.git master --progress
  Cloning into 'master'...
  remote: Counting objects: 1879515, done.        
  remote: Compressing objects: 100% (321/321), done.        
  Receiving objects:  21% (404525/1879515), 73.70 MiB | 22.00 KiB/

Then there was the long wait , Of course , When the network is good, it will be faster

The key is coming. , Be careful

the latest version MacOS Catalina The system command line executes pod setup The order ends directly ;
Don't worry , We manually install the local library , Absolutely fast
The command line does the following

 

git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/trunk
 Be careful ：
 Be careful ：
 Be careful ：
 Important things to reiterate ：

 Using this command to execute and wait for a period of time is likely to fail ,
 The reason is basically network problems ,
 Please don't worry ,
 According to the many tests of myself and my friends ,
 Only when using mobile phone network or in the early morning, the network speed will be ideal 
（ About a few minutes OK, In other cases, even if your network bandwidth is good, it is useless ）

 If you can't stay up at night , I can't get up in the morning , Mobile traffic is gone again , Then look down ！ Ah .......

Or use the following , Domestic mirror , The speed is just

 

git clone https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git  ~/.cocoapods/repos/trunk

The directory structure is shown in the figure below , If not, move it manually

If not

 

//  Install the latest version cocoapods
sudo gem install cocoapods --pre
//  Remove local master
sudo rm -fr ~/.cocoapods/repos/master
//  Remove local cache 
sudo rm -fr ~/Library/Caches/CocoaPods/
//  again setup, If it is very slow, you can use the problem 1 Solutions for （git clone）
pod setup --verbose
//  remove trunk
pod repo remove trunk

You can refer to ：CocoaPods｜ Installation process and use （macOS-Mojave）

If the installation fails all the time, please refer to here

The following paragraph omits , Look directly at The first 13 Step :

To view the file download progress, you can open another terminal window ( Shortcut key : Select the terminal and press Command+N Composite key ), Enter the following two lines to execute

 

cd ~/.cocoapods

du -sh *

perform du -sh * After that, the downloaded file size will be displayed , It can be executed multiple times to monitor the download progress , If there was a file size before , Later it became 0 了 , It could be a network problem , The download has been interrupted , You need to end the command and execute it again pod setup

13、 After the download and installation is completed, execute the following command to check whether it is available （ The first use may take a while ）

 

pod search AFNetworking

14、CocoaPods Specific use of

Create a new one Xcode engineering , Use terminal cd Go to the project directory

establish Podfile file ：

 

pod init

Then you can see a in the project directory Podfile file

open Podfile file ：

 

open Podfile

add to ：

 

pod 'AFNetworking'

Exit after saving

Start the download ：

 

pod install

I make mistakes here for the first time , Just... Again ( Look at character ) Just do it , It may be the network or other reasons .
