ruby-on-rails – rails 5 db：reset不工作

我想重置rails 5项目的数据库,但rails db：reset命令无效.

错误信息：

Permission denied @ unlink_internal - C:/sites5/dawnrebirth/db/development.sqlite3
Couldn't drop database 'db/development.sqlite3'
rails aborted!
Errno::EACCES: Permission denied @ unlink_internal - C:/sites5/dawnrebirth/db/development.sqlite3
bin/rails:4:in `require'
bin/rails:4:in `<main>'
Tasks: TOP => db:drop:_unsafe
(See full trace by running task with --trace)

解决方法

通常当rake db：reset不运行或为我工作时,我只需删除development.sqlite3和schema.rb文件,然后重新运行rake db：migrate命令重新生成这两个文件.但请注意不要在生产环境中尝试这个.
