I'm trying to build the Perseus hello-world example following:

Does it work with the latest beta (cargo install perseus-cli --version 0.4.0-beta.9)? You can run perseus new test-app with that to create a starter app automatically.

That worked! So it looks like 3.4/5 is defunct because of updated dependencies?

Interesting. What are the contents of .perseus/Cargo.toml in the v0.3.5 one? That might have some clues.

In the meantime v0.4.x is still in beta, but is, I would say, functionally very near to stable, so I would recommend using that version despite the 'beta' label.

Ok, will do.

I should point out that the book link under "What's it like?" in the Readme goes to version 3.4.

Thanks for the reminder about that link, I'll fix that!

That all looks fine, how about .perseus/builder/Cargo.toml?

Would you try changing rt-multi-thread to rt in that file? That might work...

Hmm. How about cargo check inside .perseus/engine?

There is no .perseus/engine directory. However there is a dist\target_engine directory.

Oh sorry! I meant .perseus/builder in the v0.3.5 one.

Okay, those errors should be caused by what I asked you to change before. This problem seems to be that tokio is being built for the browser, which is just plain odd. In v0.4.x, Perseus explicitly target-gates dependencies to make things clearer, but these kinds of issues of dependencies being built for the wrong platform never seemed to happen in the old versions. I wonder if this is a Windows issue somehow. Would you be able to test v0.3.5 on WSL?

@lukechu10

The error is because of tokio-rs/tokio#4979. Tokio recently added limited support for wasm whereas before it would just not work. It used to be possible to compile tokio to wasm with all the feature flags (even though it was useless) but now it produces a compile-time error instead.

@arctic-hen7

Oh, great. I'll probably have to release a new version of v0.3.x then, with the Tokio version pinned. I'll pin this issue in the meantime.

Alright, this should be fixed in v0.3.6. @coruscateor could you confirm that everything's working with that version, please?

Make sure you've run perseus clean && cargo update first?

That worked!

So should I use 0.3.6 over 0.4.0-beta.9?

Fantastic! Use whichever you prefer, honestly. 0.4.x should be faster and a bit better overall, but the docs are more complete for v0.3.6.
