我想使用django頻道和asgi來運行簡單的聊天服務器。我安裝了頻道和daphne,但是當我嘗試運行開發服務器時,出現以下錯誤。Django python無法從模塊類型導入FunctionType
Unhandled exception in thread started by <function wrapper at 0x1062fdc80>
Traceback (most recent call last):

return name_that_thing(thing.__class__)
File "/Users/yash/code/lib/python2.7/site-packages/channels/utils.py", line 16, in name_that_thing
if hasattr(thing, "__class__") and not isinstance(thing, (types.FunctionType, types.MethodType)):
AttributeError: 'module' object has no attribute 'FunctionType'
我檢出了最後一個文件,發現錯誤是與類型模塊。行import types
工作正常,但當腳本試圖呼叫types.FunctionType
它給出一個AttributeError。當我在shell上導入腳本時,它按預期工作
任何幫助,非常感謝。 :)
編輯 print(types)
輸出: <module 'types' from '/usr/local/Cellar/python/2.7.12_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/types.pyc'>
EDIT 2 我開始了另Django項目與渠道,克隆從GitHub存儲庫。當我安裝依賴關係後運行開發服務器時,它完美運行。 channels utils文件是完全相同的,所以任何幫助解釋這將有所幫助。
你可以做'打印(類型)'並顯示結果嗎? – knbk
@knbk我發佈了結果 – Superman
