問題描述

當我嘗試運行bundle exec rake test:models時，我正在使用railstutorial的草稿版本，但出現以下錯誤消息： 

rake aborted!
Errno::EACCES: Permission denied - C:/Users/Alex/Desktop/Workspace/Rails/sample_

我嘗試檢查db文件夾上的權限，還嘗試重新啟動所有內容。 我在Windows上使用的是Rails版本4.2.0beta1。 當我制作“用戶”模型時，問題開始了。 我嘗試回滾並再次遷移。

編輯：似乎我的測試數據庫在某種程度上已損壞。 如果我將/config/database.yml測試更改為/db/development.sqlite，則測試正常。

4 個解決方案

解決方案1

我刪除了舊的test.sqlite3並將其替換為development.sqlite3的副本，並將其重命名為test.sqlite3，這似乎已經解決了問題。

解決方案2

在運行rake db:migrate RAILS_ENV=test之前，運行rake db:migrate RAILS_ENV=test 。

我不是Rails專家，所以我不知道在遷移開發數據庫時是否應該自動遷移測試數據庫，但這將對其進行遷移，它解決了我的類似問題。

注意：我的操作系統是Windows 8.1

是的，問題出在Windows。 當您閱讀railsinstaller目錄中的fileutils.rb代碼時。 它想取消鏈接並要授予權限700（在unix / linux中可以找到），但不能在Windows中。 因此將無法正常工作。

這是fileutil.rb文件的片段。 

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

我注意到如果我打開了一個運行Rails服務器的終端而另一個要運行的終端，則會發生這種情況。 我的工作終端是在嘗試刪除或重置數據庫時出現問題的原因。 我關閉服務器並再次嘗試，它工作正常。
