Homebrew installation failed

[XiaoboLinlin]

brew gist-logs <formula> link OR brew config AND brew doctor output

(base) [linx6@master ~]$ brew config
bash: brew: command not found...

(base) [linx6@master ~]$ brew doctor
bash: brew: command not found...

• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

I was just trying to install Homebrew

What happened (include all command output)?

I typed down the link on Homebrew website /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)", but showed errors like this:

What did you expect to happen?

I expected homebrew can be smoothly installed.

Step-by-step reproduction instructions (by running brew commands)

I just used one command line, which caused homebrew installation errors
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
