Three golden questions: what, why, how
The manager of missing software packages for macOS (or Linux) - the documentation on the Homebrew official website will tell us in detail.
1: Check whether Homebrew is installed and downloaded:
Enter the command line brew in the terminal
(1) When the following picture appears, it means that the Mac is not installed. If necessary, you need to download Homebrew.
(2) When the following picture appears, it means that the Mac already has Homebrew and can be used normally.
Two: Download Homebrew
Enter The Missing Package Manager for macOS (or Linux) — Homebrew and copy the following command to the terminal.
It may not succeed on the first try, and an error code may appear.
Error example : LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to raw.githubusercontent.com:443
Solution: This error is because the installation source is in a foreign country and the download is very slow. Just like npm, you only need to switch the domestic source and copy the following code to the terminal.
/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
Complete solution: Because GitHub's raw.githubusercontent.comdomain name resolution is contaminated, hoststhis problem can be solved through modification.
Step 1: Check the real IP of raw.githubusercontent.com from The Best IP Address, Email and Networking Tools - IPAddress.com website. 4 IPV4 and 4IPCV6 addresses:
Step 2: Add these IPs to local hosts, use Vi editor, modify hosts
sudo vim /etc/hosts

Step 3: Finally, use the domestic image to install.
