cargo install from source fails

[YYYasin19]

Hey,

using the pre-built binary worked perfectly but running cargo install --git https://github.com/prefix-dev/pixi.git caused the following output

Am I maybe misunderstanding something regarding the installation instructions?

Inthink you need to pass ‘—locked’ as well to make sure you use the included lock file.

We should definitely update the readme!
