我尝试在Windows上从Rust中运行kotlinc。下面是我的代码的一小段:

let mut script_number: u32 = 0;
let script_path: String = format!("run/script-{script_number}.kts");

println!("Running Script: {script_number}");

let mut file = OpenOptions::new()
    .read(true)
    .write(true)
    .create(true)
    .open(script_path.clone())
    .expect("Could not create file");

file.write_all(
    self.editor
        .buffer()
        .expect("Couldn't read buffer.")
        .text()
        .as_bytes(),
)
.expect("Could not write to file");

let mut child = Command::new("./kotlinc")
    .arg("-script")
    .arg(script_path.clone())
    .stdout(Stdio::piped())
    .spawn()
    .expect("Could not execute script");

let stdout = child.stdout.take().expect("Could not read output");

let lines = BufReader::new(stdout).lines();

for line in lines {
    println!("{}", line.unwrap());
}

script_number += 1;

我得到以下输出和错误:

Running Script: 0

我怀疑这是创建的文件没有执行权限,然而,在网上搜索后,我似乎无法找到一种方法,使文件执行权限。一些答案在线引用mode函数,但该函数似乎不存在,当我试图运行它。
只是为了上下文,run目录存储了计划由程序运行的脚本,它和kotlinc(Kotlin编译器的副本)目录都是Rust src目录的兄弟目录。

我在kotlinc文件中找到了答案。需要运行的文件是./kotlinc/bin/kotlinc.bat,即:

std::process::Command::new("./kotlinc/bin/kotlinc.bat")
        .arg("-version")
        .stdout(Stdio::piped())
        .spawn()
        .expect("Could not execute script");
