This seems similar to this post, but that solution did not work, and is a few months old. nixos-version => 20.03pre194957.bef773ed53f (Markhor)
Issue
When running nix-build with nix derivation and Cargo.toml (to follow), I get the following error
error: no matching package named `cursive` found
location searched: registry `https://github.com/rust-lang/crates.io-index`
required by package `unicode_util v0.1.0 (/build/unicode_util)`
builder for '/nix/store/zs4sbvgyy08827nm11d848i13n3l6cmj-unicode_util-0.1.0.drv' failed with exit code 101
Checking both crates.io and the url given in the error message, I’m able to find the package cursive for version 0.13.0, as specified. When I open a nix-shell with cargo and build, it builds without error.
