The Mac itself is version 2.x View ruby version number Open terminal ruby -v

1. brew update

If you get an error, something is wrong with the brew update.

fatal: the remote end hung up unexpectedly

fatal: early EOF

fatal: index-pack failed

error: RPC failed; curl 18 HTTP/2 stream 3 was reset

fatal: the remote end hung up unexpectedly fatal: early EOF fatal: index-pack failed

fatal: index-pack failed

error: Fetching /usr/local/Homebrew failed!

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

This is a git error executed in terminal I read online that this is a git error so I went ahead and increased the size of the git according to the internet

git config http.postBuffer 204288000 (this size depends on your needs)

2. Continuing to run brew update, I still get the same error as in step 1

git config --list to see if the above size was set successfully.

git clone git://mirrors.ustc.edu.co.uk/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1

fatal: destination path '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core' already exists and is not an empty directory.

4 .cd "$(brew --repo)".

5.git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

mac@videozudabaoji Homebrew % cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core".

cool_mac@videozudabaoji homebrew-core % git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

brew update (it finally worked) All the commands in the image below

7 homebrew-core % brew -v and it's up to date!

8. Continue with brew install ruby
