Rails db:migrate:reset producing Errno::EACCES Permission denied @unlink_internal

Question

I am following the Rails Tutorial by Michael Hartl, and at certain points we are to run
rails db:migrate:reset
However each time I do try to do so I am faced with a permission denied error concerning the file

development.sqlite3

I have tried the following solutions I've encountered:
1. close all programs suspected of using said file and retry task
2. terminate rails console, server, editor and retry task
3. shut/restart pc and executing the task upon restart
4. executing rails db:drop

All of which have failed to allow the command to run. The only working solution is to delete the file manually and running rails db:migrate

I am running

Rails 5.0.0.1
Ruby 2.2.5p319
Sqlite3 3.14.1
Windows 10 Professional

My stack trace is:

** Invoke db:migrate:reset (first_time)
** Invoke db:drop (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Invoke db:check_protected_environments (first_time)

Tasks: TOP => db:drop:_unsafe

How can I remove this error and prevent it for future projects?

Answer 1

I get the same error using Windows 10 Pro | ruby 2.4.1 | Rails 5.1.4. I soved using:

rake db:drop:_unsafe
rake db:create
rake db:migrate
