二、办理方案

---

解读报错信息 :
Cargo, the Rust package manager, is not installed or is not on PATH. This package requires Rust and Cargo to compile extensions. Install it through the system’s package manager or via https://rustup.rs/
Rust 包管理器 Cargo 未安装或未添加到 PATH 中。此包需要 Rust 和 Cargo 来编译扩展。请通过系统的包管理器或访问 https://rustup.rs/ 举行安装。

安装 chromadb 向量数据库 时因缺少 Rust 和 Cargo 导致错误 , 需先安装 Rust 工具链（包含 Cargo）, 然后重新执行 " pip install chromadb
" 安装下令 ;
到 https://rustup.rs/ 网站 , 下载 rust 安装包 rustup-init.exe ; 点击下图中的链接 , 即可下载 ;
下载地址为 https://win.rustup.rs/x86_64 ;

运行 上述 rustup-init.exe 步伐 , 弹出如下对话框 :

上述对话框的内容如下 :

1. Welcome to Rust!
3. This will download and install the official compiler for the Rust
4. programming language, and its package manager, Cargo.
6. Rustup metadata and toolchains will be installed into the Rustup
7. home directory, located at:
9.   C:\Users\octop\.rustup
11. This can be modified with the RUSTUP_HOME environment variable.
13. The Cargo home directory is located at:
15.   C:\Users\octop\.cargo
17. This can be modified with the CARGO_HOME environment variable.
19. The cargo, rustc, rustup and other commands will be added to
20. Cargo's bin directory, located at:
22.   C:\Users\octop\.cargo\bin
24. This path will then be added to your PATH environment variable by
25. modifying the HKEY_CURRENT_USER/Environment/PATH registry key.
27. You can uninstall at any time with rustup self uninstall and
28. these changes will be reverted.
30. Current installation options:
33.    default host triple: x86_64-pc-windows-msvc
34.      default toolchain: stable (default)
35.                profile: default
36.   modify PATH variable: yes
38. 1) Proceed with standard installation (default - just press enter)
39. 2) Customize installation
40. 3) Cancel installation
41. >

复制代码

在上述下令行中 , 给出了 C:\Users\octop.cargo\bin 的路径 , 这是 Cargo 可执行步伐的目次 , 必须将该目次设置到 Path 环境中 , 才能办理 Cargo, the Rust package manager, is not installed or is not on PATH. 报错 ;

下一步选择 , 直接点击回车 , 默认安装即可 ;
安装过程中 , 会下载相关依赖 , 等待下载安装完成 ;

安装完成后 , 执行如下两个下令 , 查看是否安装完成 ;

1. rustc --version
2. cargo --version

复制代码

之后 , 下令行输入 这两个版本号 ;

1. C:\Users\octop>rustc --version
2. rustc 1.85.0 (4d91de4e4 2025-02-17)
4. C:\Users\octop>cargo --version
5. cargo 1.85.0 (d73d2caf9 2024-12-31)
7. C:\Users\octop>

复制代码

继续执行

1. pip install chromadb

复制代码

下令 , 即可安装 向量数据库 chromadb 乐成 ;
