installfest rake db：migrate系统找不到指定的路径

Question

I am going through the installfest process to get started with Ruby on Rails for the odin project, but I'm falling short at the final stage. I've installed everything they asked exactly as instructed, but when I run 'rake db:migrate' i get the message 'The system cannot find the path specified.' I cant find anything for this on the internet, the solutions I've found all say the target file has the wrong code but when I correct as advised I still get the same message.

I am doing this for a windows system.

Answer 1

If you haven't figured this out yet, it looks like running rails db:migrate should be the way it's done in Rails5 instead of rake db:migrate.

This is based off of this thread: https://www.reddit.com/r/rails/comments/60gjx3/help_when_using_rake_dbmigrate_i_get_return_error/

Answer 2

If anyone faces the same problem?! This just because the db folder does not has the development sqlite3 file : development.sqlite3 To solve it, go to your app root directory (ie: Blog, Todo [YOUR APP FOLDER]) then run this command on terminal : rails db:migrate RAILS_ENV=development

Answer 3

The error is simply showing rake db:migrate is not working.

install latest rake gem:-

gem 'rake', '~> 11.2', '>= 11.2.2' gem install rake -v 11.2.2

and restart the server: rails s
