我試圖用攤販包保存用戶生成的數據，但我得到這個錯誤我沒有在任何database.can重複的電子郵件妳告訴我什麼是錯誤。我嘗試不同的事情，但沒有得到任何結果

Answer 1

提交您的JSON文件的email是有超過null值和提交的email也注意到收錄申請，也可以指定本場unique這扔exceeption

首先刪除索引電子郵件領域這樣

db.users.dropIndex({ "email": 1 }) 

，如果你需要歸檔的電子郵件指數和申請必須有運動成爲空電子郵件

然後創建sparse index這樣

db.users.createIndex({ "email": 1 }, { sparse: true })
