Python Flask Azure Linux WebApp 因 AttributeError 失敗：模塊“enum”沒有屬性“IntFlag”

Question

Python Flask Azure Linux WebApp 失敗並顯示以下錯誤。 這個錯誤是導入kiteconnect庫后引起的。 由於 enum32 是 kiteconnect 的先決條件，因此它與 kiteconnect 一起安裝。 我已經通過 YAML 腳本手動卸載了它。 我還附上了成功卸載的屏幕截圖以及 YAML 腳本文件。

源代碼 ：

from flask import Flask, request
 from kiteconnect import KiteConnect
    
 app = Flask(__name__)
    
 @app.route('/')
 def index():
     Zerodha_API_KEY = "XXXXXXXXXX"
     Zerodha_API_SECRET= "XXXXXXXXXXX"
     Zerodha_Access_Token= "XXXXXXXXXXX"
     kite = KiteConnect(api_key=Zerodha_API_KEY)
     kite.set_access_token(Zerodha_Access_Token)
     data = kite.orders()
     print(data)
     return str(data)

按照 Grace 的建議，我通過 YAML 腳本卸載了 enum32。 這也無濟於事，因為錯誤保持不變。 用於卸載證明的 YAML 腳本

Answer 1

我在這里看到兩個不同的錯誤。

對於模塊 'enum'錯誤，您可能想要卸載enum34如果有的話）。 它以導致包裝問題而聞名。 有關更多信息，請參閱此類似帖子。 使用這個命令卸載： pip uninstall -y enum34

根據第二條錯誤消息，端口 8000 似乎未公開，這就是您的容器未響應 HTTP ping 的原因。 嘗試在配置中將 PORT 和 WEBSITES_PORT 都設置為 8000。 可以在 Azure 門戶中設置 PORT 變量。 應用服務 -> 配置 -> 應用設置 -> + PORT 8000 （源碼）

為什么 Python 3.6.1 拋出 AttributeError: module 'enum' has no attribute 'IntFlag'？
