Welcome to the Rust project! What do you want to do with x.py?
a) library: Contribute to the standard library
b) compiler: Contribute to the compiler itself
c) tools: Contribute to tools which depend on the compiler, but do not modify it directly (e.g. rustdoc, clippy, miri)
d) dist: Install Rust from source
e) none: Do not modify config.toml
Please choose one (a/b/c/d/e): d

To get started, try one of the following commands:

• x.py dist
• x.py build
x.py will now use the configuration at C:\source\rust/src/bootstrap/defaults/config.dist.toml

Rust's CI will automatically fail if it doesn't pass tidy, the internal tool for ensuring code quality.
If you'd like, x.py can install a git hook for you that will automatically run test tidy before
pushing your code to ensure your code is up to par. If you decide later that this behavior is
undesirable, simply delete the pre-push file from .git/hooks.
Would you like to install the git hook?: [y/N] y
Linked src/etc/pre-push.sh to .git/hooks/pre-push

Command "rustup" "--version" (failure_mode=Exit) did not execute successfully.
It was not possible to execute the command: Error { kind: NotFound, message: "program not found" }

Build completed unsuccessfully in 0:04:31

[wmjb]

also running x.py with "user" (as build instructions states)

python x.py setup user
results in

Building bootstrap
Finished dev profile [unoptimized] target(s) in 0.48s
ERROR: no setup rules matched ["user"]
HELP: run x.py setup --help --verbose to show a list of available paths
NOTE: if you are adding a new Step to bootstrap itself, make sure you register it with describe!

Huh.

[bjorn3]

The error about rustup not being found should be harmless, though not intentional. ./x.py setup runs rustup --version to check if rustup is available and otherwise skips linking the toolchain to rustup. This should not return in an error if rustup is not found, but as it is the last step of ./x.py setup anyway, everything should work just fine.
