是否可以在使用git添加rust cargo中的依赖时使用该路径

Question

我想添加货物依赖关系rocket-okapi作为git url，现在我添加了依赖关系像在Cargo.toml这样:

rocket-okapi = { git = "https://github.com/GREsau/okapi/tree/master/rocket-okapi"}

但是当我使用cargo build命令构建项目时，显示如下错误:

$ cargo build
Updating git repository `https://github.com/GREsau/okapi/tree/master/rocket-okapi`
warning: spurious network error (2 tries remaining): unexpected http status code: 404; class=Http (34)

if a proxy or similar is necessary `net.git-fetch-with-cli` may help here

如何将子文件夹添加为rust cargo中的依赖项?这可能吗?

Answer 1

这里有几件事需要澄清一下。

当您向Cargo.toml添加Git依赖时，它需要一个存储库。您在这里输入的URL是存储库中的目录，因此cargo会出错。

其次，当指定Git依赖项时，cargo首先在存储库根目录中查找Cargo.toml文件。如果找不到，它将搜索任何与依赖项名称相同的Cargo.toml文件。

您指定的依赖项rocket-okapi在存储库中不存在，因此cargo放弃。将依赖项的名称更改为'rocket_okapi'可以修复此问题。

TL;DR:使用这个

rocket_okapi = { git = "https://github.com/GREsau/okapi" }
