无法在 Mac m1 上遵循 yew 教程 - 使用未声明的类型“Vec”

每当我跑步时trunk build or cargo run --target=wasm32-unknown-unknown我收到一堆范围错误。

我已经跑了rustup target add wasm32-unknown-unknown and cargo install --locked wasm-bindgen-cli，但仍然没有运气。

这些错误消息是什么意思？

[编辑] 输出相当长，但它的开头是这样的：

[Edit 2]

我看到输出的开头表示我应该考虑安装目标 wasm32-unknown-unknown。

但我确实安装了它。另一个终端输出：

yew-app git:(master) ✗ rustup target add wasm32-unknown-unknown
info: component 'rust-std' for target 'wasm32-unknown-unknown' is up to date

yew-app git:(master) ✗ rustc -V
rustc 1.59.0

实际上，我分别安装了 homebrew 的 rustup 和 rustup 。我猜他们在一起玩得不好。

我从brew中卸载了rust，重新安装了rustup，安装了wasm-bindgen-cli，添加了目标并且它起作用了。

我运行过的命令列表：

rustup target remove wasm32-unknown-unknown
rustup self uninstall
brew uninstall rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup target add wasm32-unknown-unknown
cargo install --locked trunk
cargo clean
trunk clean
cargo install --locked wasm-bindgen-cli

# And finally
trunk serve
