Question

我正在编写一个派生软件包，以安装kryptco/kr，但在cargo build阶段失败。

kryptco/kr有一个子模块kryptco/sigchain，由rust编写。在kryptco/sigchain的{{3}}中，他们使用cargo web deploy命令构建其子模块。在此cargo web deploy阶段，我的程序包导出失败。

给出了这两个错误。

error: warning: replace for the non root package will be ignored, specify replace at the workspace root:
package:   /build/src/github.com/kryptco/kr/sigchain/sigchain_client/Cargo.toml
workspace: /build/src/github.com/kryptco/kr/sigchain/Cargo.toml

error: failed to fetch `https://github.com/rust-lang/crates.io-index`

Caused by:
  [6] Couldn't resolve host name; class=Net (12)

前一个错误是说要编辑Cargo.toml并添加[replace]部分，但我想避免编辑源代码。

这些错误的原因是什么？

这是我的包裹衍生品：

  };
in {
  config = {
    nixpkgs.config.packageOverrides = pkgs: { kr = kr; };
  };
}

我认为您不会对配置文件进行[replace]编辑。 cargo web deploy的构建失败是由于openssl-sys的版本过旧（已终止）。 Here's how Parity fixed it。好像他们编辑了Cargo.lock文件以依赖于该库的较新版本。
