束EXEC耙測試：機型拋出變量Errno :: EACCES：權限被拒絕

我做railstutorial的草案版本，當我嘗試運行bundle exec rake test:models我收到此錯誤信息：束EXEC耙測試：機型拋出變量Errno :: EACCES：權限被拒絕

我已經嘗試檢查我的db文件夾的權限，並試圖重新啓動一切。我在Windows上使用rails版本4.2.0beta1。當我製作「用戶」模型時，問題就開始了。我試着回滾，並再次遷移。

編輯： 看來我的測試數據庫以某種方式損壞了。如果我將/config/database.yml測試更改爲/db/development.sqlite，則測試工作正常。

我刪除了舊的test.sqlite3，並將其替換爲一個development.sqlite3的副本，並將其重命名爲test.sqlite3，這似乎解決了這個問題。

嗯它也解決了我的問題，但問題是爲什麼它的發生 – Dexture 2014-11-27 10:15:29

是的，我也想知道這一點，它不斷髮生的定期和此修復似乎只是對實際問題的症狀臨時破解。但是我最近把我的開發從windows 8改成了kubuntu，而且我還沒有再次體驗過它。 @Dexture你的操作系統是什麼？知道它是否真的是一個Windows問題可能有助於理解「爲什麼」... – madstap 2014-11-27 19:50:33

窗口，但昨晚我終於在虛擬機上安裝Fedora。這就是爲什麼大多數開發人員更喜歡窗口的軌道。 – Dexture 2014-11-28 06:18:24

在運行測試之前運行rake db:migrate RAILS_ENV=test。

我不是一個rails專家，所以我不知道是否應該在遷移開發數據庫時自動遷移測試數據庫，但是這會遷移它，並且它解決了類似的問題。

注意：我的操作系統是Windows 8.1

是的，問題出在Windows上。當您閱讀在railsinstaller目錄中找到的fileutils.rb的代碼時。它想要取消鏈接，並且要給予權限700（在unix/linux中），但不能在Windows中。所以不會工作。

以下是fileutil.rb文件的代碼片段。

def remove_file 
    platform_support { 
    File.unlink path 
    } 
end 

def platform_support 
    return yield unless fu_windows? 
    first_time_p = true 
    begin 
    yield 
    rescue Errno::ENOENT 
    raise 
    rescue => err 
    if first_time_p 
     first_time_p = false 
     begin 
     File.chmod 0700, path() # Windows does not have symlink 
     retry 
     rescue SystemCallError 
     end 
    end 
    raise err 
    end 
end

我注意到這種情況，如果我有一個終端打開運行rails服務器和另一個終端工作。我的工作終端是什麼給我這個問題，當我嘗試刪除或重置數據庫。我關閉服務器並再次嘗試，它工作正常。
