[ solved ] ImportError: cannot import name ‘url_quote’ from ‘werkzeug.urls’ ?

solution

Werkzeug==2.2.2

[ solved ] macOS keychain has expired

ปัญหาตอน start docker

sharingd wants to use the “Local Items” keychain

พอเข้าไปดู keychain เห็นว่าหลายอัน has expired

วิธีแก้คือ reset factory keychain โดยในหน้า keychain

keychain access > preferences > reset my default keychain
