How to Install Ruby on Rails 6 on Windows 10

Download & Install Ruby on Windows

You can now install both Ruby 2.6 and DevKit together from rubyinstaller website. But if you only need ruby to be installed on your windows system, just download any ruby 2.x version from Ruby without DevKit download section.

Download & Install DevKit on Windows

If you wish to install Ruby on Rails on Windows then you’ll require DevKit, which helps C-extensions compile immediately. Previously DevKit was downloaded and installed separately on Windows systems. Now, both ruby and DevKit can be installed together with just one click from rubyinstaller website.

Rails sqlite3 gem error – Windows 7/8/10

replace gem sqlite3

Replace gem sqlite3 with the following code and run bundle install

gem 'sqlite3', '~> 1.4'

replace with

gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec"

Simply run the following command, make sure you have already installed nodejs and yarn
