How to fix Rails server startup?

Question

Ruby on Rails

I went into the directory with the previously created Blog project . After typing the following commands
rails server
ruby ​​bin\rails server
outputs this

C:/Ruby/lib/ruby/gems/2.3.0/gems/sqlite3-1.3.11-x64-mingw32/lib/sqlite3.rb:6:in
`require': cannot load such file -- sqlite3/sqlite3_native ( LoadError)

Please tell me: what to do?

Answer 1

Add the
gem 'sqlite3' line to the Gemfile
to check if the gem sqlite3 and the dll itself are installed.
gem list sqlite3
should show the installed gem version.
You can check whether it is installed correctly by running.
If it does not display 1, then the problem may be in the absence of dll.
You can also try installing the sqlite3-static gem.
Before starting the Rails server, you need to check if everything is installed using
bundle check.

Answer 2

Move the hosts file from C:/Windows/system32/etc/hosts to /etc/hosts.
