Windows compatibility #1382
Description
Summary
At Windows, the rust Command::new() just will search in PATH executable file, this mean it only search suffix is .exe, but at Windows, there are still lots of file executle via cmd files, like npm.

This is a life long problem in Rust Command standard library, related to:
- Command::spawn has weird rules for finding binaries on Windows rust-lang/rust#37519
- https://doc.rust-lang.org/stable/std/process/struct.Command.html#platform-specific-behavior
Note on Windows: For executable files with the .exe extension, it can be omitted when specifying the program for this Command. However, if the file has a different extension, a filename including the extension needs to be provided, otherwise the file won’t be found.
see these document, I'm think whether we can make a polyfill for windows command search, like if Command::new("npm") is failed, then fallback to Command::new("npm.cmd").
There is some code for reproduce(should failed under Windows):
#[tokio::main]
async fn main() {
let std_out = std::process::Command::new("npm")
.arg("-v")
.output()
.expect("not found process under standard library");
let tokio = tokio::process::Command::new("npm")
.arg("-v")
.output()
.await
.expect("not found process under tokio");
