Rails db:migrate:reset产生Errno :: EACCES权限被拒绝@unlink_internal

问题描述

我正在遵循Michael Hartl编写的Rails教程，在某些时候我们要运行
rails db:migrate:reset
但是，每次我尝试这样做时，都会遇到与文件有关的权限被拒绝的错误

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

我尝试了以下遇到的解决方案:
1.关闭所有怀疑使用该文件的程序，然后重试任务
2.终止Rails控制台，服务器，编辑器并重试任务
3.关闭/重新启动电脑，并在重新启动时执行任务
4.执行rails db:drop

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

所有这些均无法使命令运行.唯一可行的解​​决方案是手动删除文件并运行 rails db:migrate

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

我正在跑步
