我是 Azure CLI 的新用户。所以，我昨天开始使用它。一切正常，直到我在控制台上收到一条消息，我需要使用 Azure login 命令再次登录。
我按照消息说的做了。打开我的浏览器并输入代码。浏览器加载页面，一切正常。但是，当我转到控制台窗口时，我收到以下消息：
error: We don't have a valid access token. Please run "azure login" again.
info: Error information has been recorded to C:\Users\julia\.azure\azure.err
error: login command failed
on the detail error file, this is the content:

当我加入门户网站时，一切正常，我的帐户处于活动状态，我可以毫无问题地创建和监控我的所有机器。这是 de Azure CLI v2.8 的特殊情况。
顺便说一句，我尝试了“azure logout and azure clear -q”命令，但没有成功。
