php - 使用流向 child_process 发送输入键

Question

我正在尝试将Enter密钥发送到 Node.js 中的 child_process。\r\n, \n, 实际上并没有将Enter密钥发送到 Psy Shell（PHP repl）。

const execa = require("execa");
const { Readable } = require("stream");

const subprocess = execa("php", ["artisan", "tinker"], { cwd: "C:\\laravel-app" });

const str = Readable.from("5+5;\r\n2+2;"); // <-- Here
str.pipe(subprocess.stdin);

(async () => {
  const a = await readableToString(subprocess.stdout);
  const b = await readableToString(subprocess.stderr);
  subprocess.kill();
  console.log(a);
  console.log(b);
})();

// This function turns a stream to a readable string
async function readableToString(readable) {
  let result = "";
  for await (const chunk of readable) {
    result += chunk;
  }
  return result;
}

输出应该是

10
4

相反，我得到

4

这与我输入5+5;2+2PsySh（手动在终端中）时得到的结果相同。
