I'm following a tutorial to set up a simple Ruby on Rails blog but when I enter "rails new blog" I get the following error. Does anyone know what the problem is? I have no experience using Rails and just recently started learning Ruby, and help would be appreciated. Thanks!
Ruby Version: ruby 2.5.3p105 (2018-10-18 revision 65156) [x64-mingw32] Rails Version: Rails 5.2.3 OS: Windows 10 64 bit
I've tried the advice in the command prompt, running the line:
gem install sqlite3 -v '1.4.0' -- source 'https://rubygems.org/'
But I get this error:
