To improve efficiency, please provide the following information. A clear problem description can be resolved more quickly:

【TiDB Environment】Testing and research, single machine deployment

【TiDB Version】v6.1.0

【Encountered Problem】

After installing tiup and executing source ${your_shell_profile}, an error occurs when running tiup playground:

tiup is checking updates for component playground ...
Starting component `playground`: /home/srtian/.tiup/components/playground/v1.10.2/tiup-playground
Using the version v6.1.0 for version constraint "".
		
If you'd like to use a TiDB version other than v6.1.0, cancel and retry with the following arguments:
	Specify version manually:   tiup playground <version>
	Specify version range:      tiup playground ^5
	The nightly version:        tiup playground nightly

Do these precautions all meet?

Refer to the FAQ below. Is it possible that the local hardware configuration cannot run a TiDB cluster?

I was able to run it yesterday, but when I opened it today, it wouldn’t run anymore.

This command starts a new cluster each time. It will not be retained.

Delete the data under the /home/srtian/.tiup/data path, log out of the current user, log back in, and then try restarting.
