我正在尝试在rust项目中添加sqlite支持。 I found rusqlite on crates.io.我将版本行添加到Cargo.toml。我添加了在rusqlite docs page上找到的一些导入(未使用)。开车修车后,我恢复了一个错误。
我还没有实现任何东西。我只是想添加依赖项并进行编译。 main.rs:
extern crate rusqlite;
use rusqlite::{Connection, Result};
use rusqlite::NO_PARAMS;
Cargo.toml:
[package]
name = "program"
version = "0.1.0"
authors = ["97"]
[dependencies]
argparse = "0.2.2"
rand = "0.4.0"
rusqlite = "0.20.0"
收到错误:

大多数包装箱仅支持最新的Rust版本。您可以尝试使用旧版本的板条箱,但最简单的方法是将Rust更新为当前支持的版本。
[如果您正在Linux发行版中使用Rust,请先将其卸载,然后从https://rustup.rs中获取它,以使其保持最新状态。 Rust生态系统的移动速度快于大多数分布。
运行rustup update
