這個問題是編碼的問題在開頭導入個包就行了，簡答粗暴

import encodings.idna

補充：執(zhí)行Python出現LookupError: unknown encoding: cp65001解決辦法

在執(zhí)行fetch v8時出現

E:\GitProject\svn_v8>fetch v8
Running: 'E:\GitProject\libcef\depot_tools\python276_bin\python.exe' 'E:\GitProj
ect\libcef\depot_tools\gclient.py' root

LookupError: unknown encoding: cp65001

LookupError: unknown encoding: cp65001

出現此錯誤后改變編碼方式即可解決：

chcp 1252

也可以通過修改注冊表CodePage值來設置默認字符編碼

HKEY_CURRENT_USER\Console\%SystemRoot%_system32_cmd.exe\CodePage
