rust - 覆盖 Rust 安装默认路径 `$HOME/.cargo` 和 `$HOME/.rustup`

Question

在 Rust 中，默认情况下，文件放在 $HOME/.cargo 和 $HOME/.rustup 中。有什么方法可以覆盖这些默认值吗？

我正在尝试调试一个模糊的问题，我想尝试更改文件位置。

这解释了in the documentation :

rustup allows you to customise your installation by setting the environment variables CARGO_HOME and RUSTUP_HOME before running the rustup-init executable. As mentioned in the Environment Variables section, RUSTUP_HOME sets the root rustup folder, which is used for storing installed toolchains and configuration options. CARGO_HOME contains cache files used by cargo.

不要忘记更新 $PATH 否则您将无法使用二进制文件。此外，如果您希望该设置是永久性的，请从您的 shell 配置中导出这些变量(例如 .bashrc 或 .zshrc):

Note that you will need to ensure these environment variables are always set and that CARGO_HOME/bin is in the $PATH environment variable when using the toolchain.
