AI-generated summary

To clone the optimism code repository, use the command "git clone https://github.com/ethereum-optimism/optimism.git" and navigate to the cloned directory using "cd optimism". Install Node.js version 16 instead of version 18, as the latter may cause errors during the compilation of optimism. Use the command "brew install node@16", followed by "brew unlink node" and "brew link --force --overwrite node@16". Additionally, install Python 2 by downloading the macOS 64-bit installer. Finally, run "yarn" to install the dependencies and "yarn build" to build the project.

Clone the optimism code repository:

git clone https://github.com/ethereum-optimism/optimism.git
cd optimism

Install Node

If you have previously installed Node version 18, which is too high and causes errors when compiling optimism, now choose Node 16.

brew install node@16
brew unlink node
brew link --force --overwrite node@16

Install Python 2

macOS comes with Python 3 installed by default. You can download Python 2 here and select "macOS 64-bit installer".

Run yarn to install dependencies

If you encounter the following error during the dependency installation process:

Try 'libtool --help' for more information.
libtool:   error: unrecognised option: '-static'

It means that you may have previously installed libtool using brew. You can uninstall it:

~/github/optimism   which libtool
/opt/homebrew/opt/libtool/libexec/gnubin/libtool


brew uninstall --ignore-dependencies libtool

Run yarn build
