如何查看像这样的事件工具链的已安装目标？

Answer 1

Rustup 只会在有多个可用部分时显示部分。例如，如果您只有一个工具链，stable ，和一个目标，x86_64-unknown-linux-gnu ，这就是你所看到的:

> rustup show
Default host: x86_64-unknown-linux-gnu
rustup home:  /home/kmdreko/.rustup

stable-x86_64-unknown-linux-gnu (default)
rustc 1.61.0 (fe5b13d68 2022-05-18)

但是如果你有两个可用的目标，比如你跑了 rustup target add wasm32-unknown-unknown ，然后您会看到“事件工具链的已安装目标”部分:

> rustup show
Default host: x86_64-unknown-linux-gnu
rustup home:  /home/kmdreko/.rustup

installed targets for active toolchain
--------------------------------------

wasm32-unknown-unknown
x86_64-unknown-linux-gnu

active toolchain
----------------

stable-x86_64-unknown-linux-gnu (default)
rustc 1.61.0 (fe5b13d68 2022-05-18)

如果你有两个可用的工具链，就像你一样，然后运行 ​​ rustup toolchain add nightly ，然后您还会看到“已安装的工具链”部分:

> rustup show
Default host: x86_64-unknown-linux-gnu
rustup home:  /home/kmdreko/.rustup

installed toolchains
--------------------

stable-x86_64-unknown-linux-gnu (default)
nightly-x86_64-unknown-linux-gnu

installed targets for active toolchain
--------------------------------------

wasm32-unknown-unknown
x86_64-unknown-linux-gnu

active toolchain
----------------

stable-x86_64-unknown-linux-gnu (default)
rustc 1.61.0 (fe5b13d68 2022-05-18)
