问题描述

使用 az login指令登录，遇见 OS Error: [WinError -2146893813] : '', 在指令中添加 --debug后，输出的错误消息为：

urllib3.connectionpool: Starting new HTTPS connection (1): *****.******.com:443
urllib3.connectionpool: https://****.****.com:443 "POST /adfs/services/trust/13/usernamemixed HTTP/1.1" 200 7155
urllib3.connectionpool: Starting new HTTPS connection (1): login.chinacloudapi.cn:443
urllib3.connectionpool: https://login.chinacloudapi.cn:443 "POST /organizations/oauth2/v2.0/token HTTP/1.1" 200 4488
msal_extensions.persistence: DPAPI error likely caused by file content not previously encrypted. App developer should migrate by calling save(plaintext) first.
Traceback (most recent call last):
  File "D:\a\1\s\build_scripts\windows\artifacts\cli\Lib\site-packages\msal_extensions/persistence.py", line 180, in load
  File "D:\a\1\s\build_scripts\windows\artifacts\cli\Lib\site-packages\msal_extensions/windows.py", line 114, in unprotect
OSError: [WinError -2146893813] : ''

从以上错误信息来看，只能发现与 MSAL扩展persistence.py有关，但是在执行的机器中，并不存在错误消息中的目录（D:\a\1\s\build_scripts\windows\artifacts\cli\Lib\site-packages\ )

在升级 azure cli的版本后( az upgrade或下载最新的msi安装包:https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-windows?tabs=azure-cli) ，OSError 的错误代码一样，但是有了更具体的错误消息和提示信息：

cli.azure.cli.core.azclierror: Decryption failed:[WinError -2146893813] Key not vaid for use in specified state..
