After using xclip in linux(ubuntu:20.04) py(calling pyperclip.copy(message)), the node failed to receive the result and eventually timed out

[zq0904]

Describe the bug
ts-node-dev test/test_pyperclip.ts
I found that the process is stuck. I'm not sure if it's a problem with the implementation of pyperclip.copy itself in the linux system or a problem with the implementation of python-shell itself (such as using clipping or buffer conflicts, etc.
What I can be sure of is that pyperclip.copy works as scheduled and it won't block the py process, but the node process just keeps waiting, which puzzles me a lot

Python code

# test_pyperclip.py
# test_pyperclip.py
import pyperclip


def main():
    message = "你好"
    pyperclip.copy(message)
    return


if __name__ == "__main__":
    main()

Javascript code

import path from 'path'
import { PythonShell } from 'python-shell'

PythonShell.run(path.resolve(__dirname, 'test_pyperclip.py'), {
  pythonPath: path.resolve(__dirname, '../.venv/bin/python3'),
  env: { ...process.env, DISPLAY: ':1' },
}).then(
  (res) => {
    console.log({ res })
  },
  (err) => {
    console.log({ err })
  }
)

Expected behavior
The code will execute to console.log({res}).

Actual behavior
Even if the py process has ended after the PythonShell.run() call, the Promise remains in the pending state

• OS: [e.g. ubuntu:20.04 & apt-get install xclip]
