error: failed to get winit as a dependency of package `iced_winit v0.3.0

[alyferryhalo]

Hey there!

I tried to install ENSnano according to the instructions:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
git clone https://github.com/thenlevy/ensnano.git
cd ensnano
source "$HOME/.cargo/env"
cargo run --release

But then I got an error after the last command

I used macOS Monterey 12.1, the Rust version is stable 1.63.0 (bottled)

How can I fix this problem?

Hi,
Cargo is complaining about not being able to resolve a certain commit which is apparently accessible
Could you try to run
cargo update
at the root of the repository, and then cargo run --release again ?

Alternatively, since you are using macOS you should be able to use the compiled binaries. These are up-to-date with the current main branch of the repo https://github.com/thenlevy/ensnano/releases/tag/0.4.0

Unfortunately, the first option didn't work, but the second solved my problem. Thanks!

In case anyone run into the same problem and find this thread, I have been able to reproduce this problem on an other machine. The problem on that machine was that Cargo was not up to date.
This can be solved by running

rustup default stable
rustup update stable

Alternatively you may be able to upgrade Cargo via your package manager but I have not tried it myself.
