error: could not compile `seed` due to 2 previous errors

I used seed-quickstart for this, and tried updating to the latest version.

Edit: ._. this may have been a user issue, I wasn't getting any errors in the actual project though... I was doing the todo list tutorial and got the error at project-setup. Delete & re-init seems to have solved it though.

I have this problem too! following the (admittedly quite old) intoduction to rust web applications book

Same here. Might be quickstart that is broken but from the error it's the seed crate and not the quickstart. Tried 3 different versions of seed 0.7.0/0.8.0 and 0.9.1.

Error is happening in a fresh clone and CI https://github.com/OpenFlowLabs/expensebills/runs/7081134689?check_suite_focus=true

@MartinKavik this is a blocker right now.

@j0lol and @Toasterson this is a duplicate of #687

Please use

[patch.crates-io]
seed =  { git = "https://github.com/seed-rs/seed" }

until v0.9.2 is released
