在 Rails 中，db:drop 授予关于 development.sqlite3 的权限被拒绝答案

【问题标题】：With Rails, db:drop gives permission denied regarding development.sqlite3在 Rails 中，db:drop 授予关于 development.sqlite3 的权限被拒绝
【发布时间】：2026-01-07 22:00:01
【问题描述】：

我是 Rails 新手。

我收到一个错误，就像提到的 rails 5 db:reset not working 但这不是那个问题的重复，因为那里接受的答案对我不起作用。

我知道 db:reset 涉及到 db:drop，我发现我无法执行 db:reset，然后我尝试了 db:drop 发现我也无法执行此操作，这是更基础的，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

如下图所示

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!
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>

我在这个问题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）“只需删除 development.sqlite3 和 schema.rb 文件并重新运行 rake db ：迁移”

我不需要停止 rails 服务器，因为我还没有启动它。我做了那个删除，Rails db:migrate，然后尝试了 db:drop，但仍然出现错误。

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>


C:\rubytest\blah2>del C:\rubytest\blah2\db\development.sqlite3

C:\rubytest\blah2>dir C:\rubytest\blah2\db
23/12/2017  10:06 PM               370 seeds.rb

C:\rubytest\blah2>


C:\rubytest\blah2>rails db:migrate

C:\rubytest\blah2>dir C:\rubytest\blah2\db
23/12/2017  10:13 PM             5,120 development.sqlite3
23/12/2017  10:13 PM               786 schema.rb
23/12/2017  10:06 PM               370 seeds.rb
C:\rubytest\blah2>

但我仍然得到错误

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>

我也尝试了rails db:reset rails_env=development（我知道默认是开发..），我尝试了rails db:reset rails_env=test，正如这里提到的Errno::EACCES: Permission denied @ unlink_internal when running rake test:models，但没有任何区别

这看起来像是一个未解决的错误https://github.com/rails/rails/issues/31589（打开但没有响应）和https://github.com/rails/rails/issues/27015（关闭）

已添加

我在这里包含了两个来自进程监视器的日志示例，这可能暗示了这个问题。我做了一个过滤器，其中路径包含红宝石。

第一个日志，较小。

我开始在进程监视器中捕获事件，就在 rails db:drop 之前，然后我就停止了。

C:\crp\aaa1>path
PATH=C:\Ruby24-x64\bin;C:\Program Files\nodejs


c:\crp>rails new aaa1
...

C:\crp\aaa1>rails db:drop

我在上面的日志中注意到的主要内容是很多“未找到路径”。不知道正常不正常。

我从不同的路径再次尝试，这次我的环境路径更长。尽管日志更长，但我仍然在命令行上遇到相同的错误，并且我注意到有关共享冲突的错误，这可能不相关，因为在本文前面包含的日志中，我没有收到此类共享冲突错误进程监视器日志，但仍然在命令行出现权限被拒绝错误。

【问题讨论】：

Errno::EACCES: Permission denied您是否尝试过使用具有所需权限的用户，或者通过授予权限？
@SebastianPalma 我在管理 cmd 提示符下进行了尝试，这在 Windows 中几乎是可以或需要的特权。我不清楚它试图做什么，它认为它被拒绝了。从 Windows 的角度来看，我什至可以从常规 cmd 提示符中删除该文件。
您是否同时使用任何数据库浏览器或其他软件来探索锁定您的数据库的数据库？ @barlop
@AakashGupta 不，我没有运行任何数据库浏览器或任何锁定文件的软件。正如我所说，文件没有被锁定。如果我愿意，我可以删除该文件，并且按照我的 q 中提到的那样完成，但它没有帮助。

【解决方案1】：

这条线就可以了，rails db:drop:_unsafe

见https://github.com/rails/rails/issues/31589

C:\rubytest\h\testaa1>rails db:drop:_unsafe
Dropped database 'db/development.sqlite3'
Dropped database 'db/test.sqlite3'

C:\rubytest\h\testaa1>

【讨论】：

@worrawut 我的问题显示Rails 5.1.4 所以不是最新的，而是rails 5。你是否尝试过你有rails 4.x/4.x.x，有问题，没有升级年，然后升级到 rails 5.x/5.x.x?
很抱歉我的信息被误解了。我的意思是我也运行 Rails 5 (5.2.0)，你的回答帮助我解决了同样的问题。美好的一天！
@worrawut 点击 + 进行投票就足够了。你的评论也提醒我接受答案（因为我也写了这个问题！）我在提出问题后花了一年时间才找到解决方案！因为它，我已经使用运行 osx 的 mac 一年了。 Rails 团队很少关心 Windows 用户。
