step 1:
git clone https://github.com/ekzhang/sshx.git
step 2:
git checkout tags/v0.2.3 -b v0.2.3
dtep 3:
cargo install --path crates/sshx

will output error:

error: could not compile `proc-macro2` (lib) due to 2 previous errors
warning: build failed, waiting for other jobs to finish...
error: failed to compile `sshx v0.2.3 (E:\work\sshx\crates\sshx)`, intermediate artifacts can be found at `E:\work\sshx\target`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

if need, I can try to deal it.

What's your rustc version? I googled this and found https://users.rust-lang.org/t/cannot-compile-simple-tokio-example/109956/5 as a potential solution.

yes，I updated rust version to 79, use nightly, but there still other errors:
