更新

最近在测试时发现无法安装 tauri-app, 需要更新 cargo

Caused by:
  failed to parse the `edition` key

Caused by:
  this version of Cargo is older than the `2021` edition, and only supports `2015` and `2018` editions.

解决方式

└──╼ rustc --version
rustc 1.46.0 (04488afe3 2020-08-24)
└──╼ rustup update stable
...
└──╼ rustc --version
rustc 1.64.0 (a55dd71d5 2022-09-19)
