【问题描述】：

我收到了这个奇怪的错误：

cargo build
    Updating crates.io index
error: failed to get `anyhow` as a dependency of package `FlexDB v0.1.0 (E:\projects\FlexDB)`

Caused by:
  failed to load source for dependency `anyhow`

Caused by:
  Unable to update registry `crates-io`

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

Caused by:
  missing delta bases; class=Indexer (15)

我的cargo.toml 文件如下所示：

[package]
name = "FlexDB"
version = "0.1.0"
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
anyhow = "1"

我不知道该怎么办，我做到了：

rustup update
重启电脑

【问题讨论】：

听起来您遇到了互联网问题？你可以试试 cargo clean 和 cargo build。

@kornel 的回答确实解决了这个错误，

“您的 ~/.cargo/registry/index 目录似乎已损坏。删除它并再次运行 cargo update。”
