[flaneur2020]

is the python3 command available in the major os environment like Darwin, ubuntu, fedora? q.q

[yihong0618]

ubuntu and Darwin I think the answer yes

And I saw python3 command in dev_setup https://github.com/datafuselabs/databend/blob/main/scripts/setup/dev_setup.sh#L298

or maybe we can make the command from setup_dev too?

[flaneur2020]

agree, we can take the python commands the same among the script files

[yihong0618]

users env may have both python and python3 we can get the python env command in setup ln the python3 command.
