master channel fails to run in git bash

[tksoh]

Ran into issue when I tried to use the master channel for the first time...

$ puro --version
[i] Puro 1.4.11 (distribution/windows-x64)
    Dart 3.7.2 (stable) (Tue Mar 11 04:27:50 2025 -0700) on "windows_x64"

$ puro create master
[✓] Created new environment at `C:\Users\teeka\.puro\envs\master\flutter`

$ puro ls
[i] Environments:
    ~ stable (stable / 3.35.4 / d693b4b9db)

$ puro -e stable flutter --version

$ puro -e master flutter --version

Anything I missed?

Can you try puro rm master and then puro create stable?

[tksoh]

Can you try puro rm master and then puro create stable?

Sorry I'm slightly confused. Did you mean puro create master? If so, then I already did that, but it's still giving the same error.

Just found out that puro gave the error when running in git bash (my apology for failing to mention this earlier). When running in cmd.exe, things seem to work fine somehow.

Obviously cmd.exe isn't my favorite work env, so it's important to rectify/workaround this as far as I'm concerned. Thanks.

Just to update that I don't see the same error in PowerShell. So this issue seems to be specific to git bash.

Here are the output of puro --verbose in git-bash and PowerShell for comparison.

This is probably just a busted git bash install, use --log-level=4 to see what commands its actually running

[tksoh]
