登录gcpsql：如何确保PromptSession被导入或删除

Question

我正在尝试使用云Shell来更新一些用户权限。I am logging in using ^{}

gcloud sql connect my-instance
Whitelisting your IP for incoming connection for 5 minutes...done.
Connecting to database with SQL user [sqlserver].********************************************************************************
Python command will soon point to Python v3.7.3.
Python 2 will be sunsetting on January 1, 2020.
See http://https://www.python.org/doc/sunset-python-2/
Until then, you can continue using Python 2 at /usr/bin/python2, but soon
/usr/bin/python symlink will point to /usr/local/bin/python3.
To suppress this warning, create an empty ~/.cloudshell/no-python-warning file.
The command will automatically proceed in  seconds or on any key.

A）我已经使root用户的密码如此不安全和容易，我不可能打错它。你知道吗

B）现在是一月三号，所以我真的不知道这个Python版本的错误是关于什么的。我制作了这个文件，但仅供参考~/.cloudshell不存在，所以我必须先制作它。即便如此，它只是抑制了版本警告，当我尝试登录时，主要错误仍然存在。你知道吗

The documentation承认有几个其他的登录方法使用glcoud beta sql connect，但这又给我带来了另一个错误

2020/01/04 18:38:41 Rlimits for file descriptors set to {&{8500 1048576}}
2020/01/04 18:38:41 invalid json file "/tmp/tmp.s38C662KKr/legacy_credentials/me@gmail.com/adc.json": open /tmp/tmp.s38C662KKr/legacy_credentials/me@gmail.com/adc.json: no such file or directory
ERROR: (gcloud.beta.sql.connect) Failed to start the Cloud SQL Proxy.

与alpha相同。你知道吗

这是我在cloudshell中输入的第一个东西，所以我无法想象什么会破坏PromptSession。你知道吗

如何解决此错误并使用Cloud Shell登录到SQL Server？

Answer 1

在尝试从Cloud Shell连接时很可能出现问题（我使用此命令从计算引擎实例连接）；可能与Python run-time/environment变量有关。据报道here。工程部已经意识到并正在调查此事。你知道吗
