Invalid Route Base on 0.5-rc.1

[HamishWHC]

Trying to build a project with a dynamic path handler. Have found that I can't build even this route:

#[get("/hello/<name>")]
fn hello(name: &str) -> String {
    format!("Hello, {}!", name)
}

I get this error:

Error: invalid route base: /hello/<name>
   >> unexpected token '<' at index 7

What am I missing?

Extra info: I can compile with static paths just fine. I'm on WSL 2. Can't seem to compile the hello example with this error:

error: /home/hamishwhc/projects/Rocket/examples/target/debug/deps/librocket_codegen-c6b35877a4b83c8c.so: undefined symbol: _ZN5alloc7raw_vec19RawVec$LT$T$C$A$GT$11allocate]in17h47bab2c373b57925E
  --> /home/hamishwhc/projects/Rocket/core/lib/src/response/mod.rs:30:9
   |
30 | pub use rocket_codegen::Responder;
   |  

Although if I compile the example on Windows instead of WSL, it runs just fine. I'll try my project on Windows, but would prefer to stay in WSL.

You're not showing us the rest of your code. The error indicates that you're writing .mount("/hello/<name>", ...) elsewhere, which is completely malformed. Even a cursory reading of the documentation, or a proper copying of any of the myriad examples, would resolve and answer your question. Please read the documentation.

The error message should be indicating more information. Is that really all of the log output that you get? Could you post everything your terminal is showing you?

In the future, you'll want to provide us with more information than two sparse snippets of code and terminal output.

Here's the full terminal log:

Thanks for your help.

Are you suppressing log output? What does your Rocket.toml look like?

[HamishWHC]

Rocket.toml:

[development]
address = "localhost"
port = 9989

We should definitely be providing more context for the error. I'll look into it soon.
