[ruby on rails] ruby ​​uses vscode for development

ruby LSP implementation

The ruby ​​plug-in recommends using this to implement it, but now it is very slow when loading file indexes, sometimes good or bad, so now it is recommended to use Solargraph to implement it.

  • ruby LSP requires ruby ​​version 3 or above. If used in an old version, you need to specify the bundleGemfile path.
    Tutorial on using ruby ​​LSP with old versions of ruby
$ mkdir ruby-extensions
$ cd ruby-extensions
$ touch Gemfile
$ touch .ruby-version

# Gemfile
source 'https://rubygems.org'

ruby '3.1.4'

# Ruby LSP
gem 'rubocop'
gem 'ruby-lsp'

# .ruby-version
3.1.4
