"manifest path is a virtual manifest, but this command requires running against an actual package" 是什么意思？

Question

我正在尝试构建一个 Rust 项目 (xray)。当 运行 cargo run 我收到以下错误消息

error: manifest path D:\xray\building\xray\Cargo.toml is a virtual manifest, but this command requires running against an actual package in this workspace

这到底是什么意思，如何解决？我正在使用 Cargo 版本 0.25.0 和 Rust 版本 1.24.1.

Answer 1

清单中包含包和工作区部分无法正常工作。请检查 Cargo.toml 并从中删除包。

Virtual Manifest是新概念，请阅读文档熟悉它。希望它对你有价值。

Answer 2

你的 Cargo.toml 是 virtual manifest.

In workspace manifests, if the package table is present, the workspace root crate will be treated as a normal package, as well as a workspace. If the package table is not present in a workspace manifest, it is called a virtual manifest.

When working with virtual manifests, package-related cargo commands, like cargo build, won't be available anymore. But, most of such commands support the --all option, will execute the command for all the non-virtual manifest in the workspace.

cargo run 不起作用，因为 cargo 不知道 什么 到 运行。有两种选择：

1. --manifest-path <PATH>：您想要 运行.
的箱子 Cargo.toml 的路径
2. -p, --package <SPEC>: 你想要的包 运行.

你的情况可能是 cargo run --package xray_cli
