Why can't I run examples with my installed version of perseus?

git clone https://github.com/arctic-hen7/perseus.git ; build release perseus
cd perseus/examples/demos/auth; perseus serve
some error report

The perseus CLI you have installed does not match the version of the main repository, so you need to use the bleeding edge version of the CLI. You can do this with bonnie dev example demos auth serve in your case. Make sure you run bonnie setup first. (You can install Bonnie with cargo install bonnie, and you'll also need rust-script.)

The reason for this is that the main repo makes all its examples, including the examples/demos/, generic over server integrations, which means feature flags need to be provided to make everything work. This is automatically performed by the Bonnie scripts in the repo.

thx,🍺

• use bonnie:

cargo install bonnie rust-script
bonnie setup
bonnie dev example demos auth serve

• use perseus

git clone https://github.com/arctic-hen7/perseus.git
cd perseus/examples/demos/auth
perseus serve '--cargo-engine-args=--features "perseus-integration/warp" ' -w

Correct, but the second method will only work sometimes. If a breaking change is added in the latest commit, that will fail.
