brew doctor output

brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /home/tri/.pyenv/shims/python-config
  /home/tri/.pyenv/shims/python3-config
  /home/tri/.pyenv/shims/python3.10-config

Verification

• 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 am doing a fresh install of brew on my WSL2 setup. After installing fd, exa, ripgrep and trying to run the these commands I am getting the following errors:

-bash: /home/linuxbrew/.linuxbrew/bin/fd: cannot execute binary file: Exec format error
-bash: /home/linuxbrew/.linuxbrew/bin/exa: cannot execute binary file: Exec format error
-bash: /home/linuxbrew/.linuxbrew/bin/ripgrep: cannot execute binary file: Exec format error

Whereas the other installs like git or bpytop or mc has been working fine without any issues

Is there something I am missing here

What happened (include all command output)?

fd
zsh: exec format error: fd

exa
zsh: exec format error: exa

and so on

What did you expect to happen?

Expecting commands like fd, exa etc to run

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

brew install fd 
fd 

or brew install exa 
exa

I don't do Windows, but comparing the Kernel line of brew config against microsoft/WSL#4555 (comment), it sure looks like you're actually running WSL1, which neatly explains the problem you're seeing.

Alternatively, try running ls /run/WSL/. If you get a File not found, that confirms you're running WSL1.

Thank you. The WSL version was indeed was the issue. I had installed in a new laptop so I hoped that WSL2 would be installed by default.
