Rails engineer environment construction ruby2.7.1

I will write it as a memorandum because my mac broke down and I had to reinsert it. It also lists non-essential settings such as heroku and item2 settings.

Command Line Tools

xcode-select --install

Is heavy, so install xcode and do it here

ruby install

Check the installable version

rbenv install -l


rbenv install 2.7.1

I saw this when I couldn't (https://github.com/rbenv/ruby-build/issues/1409)

Global settings

rbenv global 2.7.1


ruby --version


** A tool for managing gem dependencies and versions **

gem install bundler


gem install rails
rbenv rehash

yarn Required for installing webpacker

brew install yarn

I don't know, but it seems to be good to put this in ([Reference](https://qiita.com/Alex_mht_code/items/d2db2eba17830e36a5f1#5%E8%BF%BD%E8%A8%98rbenv-communal-gems%E3%] 81% AF% E5% 85% A5% E3% 82% 8C% E3% 81% A6% E3% 81% 8A% E3% 81% 8D% E3% 81% BE% E3% 81% 97% E3% 82% 87% E3% 81% 86)))

brew install rbenv-communal-gems

webpacker Since webpacker has become a standard specification from Rails6, it is necessary to install yarn.

rails webpacker:install

Ruby 2.7 and Rails 6 with db: create to turn off warnings


export RUBYOPT='-W:no-deprecated -W:no-experimental'


brew install [email protected]


mysql --version
