leptos with axum: Issue with wasm-bindgen versions
问题
我刚刚开始学习Rust和Leptos，所以对整个Rust / Cargo生态系统也相当新奇。
我正在按照leptos教程来设置一个新的leptos项目，使用axum。当我尝试用以下命令启动项目时：
cargo leptos watch
我遇到了以下问题：
错误：位于`/Users/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/cargo-leptos-0.1.9/src/compile/front.rs:46:30`
原因是：
0：位于`/Users/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/cargo-leptos-0.1.9/src/compile/front.rs:111:10`

看起来用于创建此wasm文件的Rust项目与此二进制文件使用的wasm-bindgen版本绑定格式不同：
Rust wasm文件模式版本：0.2.84
此二进制文件模式版本：0.2.86
目前，绑定格式不稳定，以至于这两个模式版本必须完全匹配。您可以通过更新此二进制文件或Rust项目中的wasm-bindgen依赖项来实现这一点。
您应该能够使用以下命令更新wasm-bindgen依赖项：
cargo update -p wasm-bindgen --precise 0.2.86
不要忘记重新编译您的wasm文件！或者，您可以使用以下命令更新二进制文件：
cargo install -f wasm-bindgen-cli --version 0.2.84
如果此警告仍未消失，并且您不确定该怎么做，请随时在https://github.com/rustwasm/wasm-bindgen/issues上报告问题！
我尝试了建议的两种解决方案。第一种给我带来了以下错误：
更新crates.io索引
错误：无法选择要求`wasm-bindgen = "0.2.84"`的版本
找到的候选版本与之不匹配：0.2.86
搜索位置：crates.io索引
由`start-axum v0.1.0 (...)`包需要
也许某个crate已经更新，但忘记重新生成了吗？
第二个选项没有给我带来错误，但没有解决最初的问题。
有人之前遇到过这个问题吗？

I am just getting started with Rust and Leptos, so I'm also quite new to the whole rust / cargo ecosystem.
I was following the leptos tutorial to setup a new leptos project using axum. When I tried starting the project with
cargo leptos watch
I ran into the following issue:
Error: at `/Users/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/cargo-leptos-0.1.9/src/compile/front.rs:46:30`
Caused by:

it looks like the Rust project used to create this wasm file was linked against
version of wasm-bindgen that uses a different bindgen format than this binary:
rust wasm file schema version: 0.2.84
this binary schema version: 0.2.86
Currently the bindgen format is unstable enough that these two schema versions
must exactly match. You can accomplish this by either updating this binary or
the wasm-bindgen dependency in the Rust project.
You should be able to update the wasm-bindgen dependency with:
cargo update -p wasm-bindgen --precise 0.2.86
don't forget to recompile your wasm file! Alternatively, you can update the
binary with:
cargo install -f wasm-bindgen-cli --version 0.2.84
if this warning fails to go away though and you're not sure what to do feel free
to open an issue at https://github.com/rustwasm/wasm-bindgen/issues!
I tried both suggested solutions. The first one gives me
Updating crates.io index
error: failed to select a version for the requirement `wasm-bindgen = "=0.2.84"`
candidate versions found which didn't match: 0.2.86
location searched: crates.io index
required by package `start-axum v0.1.0 (...)`
perhaps a crate was updated and forgotten to be re-vendored?
The second option gives me no errors, but it doesn't resolve the initial problem.
Anyone had this issue before?

只需将Cargo.toml中的was-bindgen更改为wasm-bindgen = "0.2.86"，现在可以正常工作 - 如@kmdreko建议的那样。
cargo update似乎不会强制更新包，如果它们被定义为精确版本（=）。
英文:
Just changed the was-bindgen in Cargo.toml to wasm-bindgen = "=0.2.86" and now it works - as also suggested by @kmdreko.
cargo update does not seem to force update packages, if they are defined with an exact version (=)
