我是铁杆新手。
我收到的错误更像是rails 5 db:reset not working提到的错误，但这不是该问题的重复，因为接受的答案并不适用于我。
我理解db：reset涉及db：drop，我发现我无法做db：reset，然后我尝试了db：drop，发现我也做不到，这是更为根本，并给出了同样的错误。
我得到的错误是当我执行rails db：drop时。我得到Permission denied @ unlink_internal - C:/rubytest/blah2/db/development.sqlite3
如下所示
C:\rubytest>rails --version
Rails 5.1.4
C:\rubytest>
C:\rubytest>rails new blah2
...
C:\rubytest\blah2>bundle update
...
C:\rubytest\blah2>rails db:drop
Permission denied @ unlink_internal - C:/rubytest/blah2/db/development.sqlite3
Couldn't drop database 'db/development.sqlite3'
rails aborted!

bin/rails:4:in `require'
bin/rails:4:in `<main>'
Tasks: TOP => db:drop:_unsafe
(See full trace by running task with --trace)
C:\rubytest\blah2>
我在这个问题的顶部提到的链接中接受的答案建议（注意不要在生产环境中这样做）＆＃34;只需删除development.sqlite3和schema.rb文件并重新运行rake db：migrate＆＃34;
我没有必要停止使用rails服务器，因为我还没有启动它。我做了那个删除，并且rails db：migrate，然后尝试了db：drop并且仍然出错。
C:\rubytest\blah2>dir C:\rubytest\blah2\db
...
23/12/2017 10:07 PM 0 development.sqlite3
23/12/2017 10:06 PM 370 seeds.rb
..

C:\rubytest\blah2>dir C:\rubytest\blah2\db

23/12/2017 10:06 PM 370 seeds.rb
C:\rubytest\blah2>
然而我仍然得到错误
C:\rubytest\blah2>rails db:drop
Permission denied @ unlink_internal - C:/rubytest/blah2/db/development.sqlite3
Couldn't drop database 'db/development.sqlite3'
rails aborted!
Errno::EACCES: Permission denied @ unlink_internal - C:/rubytest/blah2/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)
C:\rubytest\blah2>
我也试过了rails db:reset rails_env=development（我知道默认情况下是开发方式..）我尝试了rails db:reset rails_env=test，如此处所提到的Errno::EACCES: Permission denied @ unlink_internal when running rake test:models但是没有区别
这看起来像一个未解决的错误https://github.com/rails/rails/issues/31589（打开但没有响应）和https://github.com/rails/rails/issues/27015（已关闭）
加
我在此处包含了两个来自进程监视器的日志示例，这可能暗示了该问题。我做了一个路径包含ruby的过滤器。
第一个日志，更小。
我在进程监视器中开始捕获事件，就在rails db：drop之前，我刚刚停止它。
C:\crp\aaa1>path

c:\crp>rails new aaa1

我在上面的日志中注意到的主要内容是很多＆＃34; PATH NOT FOUND＆＃34;。我不知道这是否正常。
我从不同的路径再次尝试，这次我的环境路径更长。我在命令行上仍然遇到相同的错误，虽然日志更长，我注意到有关共享冲突的错误，这可能不相关，因为在本文前面的日志中，我没有遇到此类共享冲突错误进程监视器日志，但仍然在命令行中获得了权限被拒绝错误。
