无论文件是否存在，如何确保路径是可读和可写的？NodeJS

const fs = require('fs');

function checkPathAccessibility(path) {
  fs.access(path, fs.constants.R_OK | fs.constants.W_OK, (err) => {
    if (err) {
      console.error(`${path} is not accessible`);
    } else {
      console.log(`${path} is accessible`);
    }
  });
}

checkPathAccessibility('/path/to/file.txt');

const fs = require('fs');

function checkPathAccessibility(path) {
  if (fs.existsSync(path)) {
    try {
      fs.accessSync(path, fs.constants.R_OK | fs.constants.W_OK);
      console.log(`${path} is accessible`);
    } catch (err) {
      console.error(`${path} is not accessible`);
    }
  } else {
    console.error(`${path} does not exist`);
  }
}

checkPathAccessibility('/path/to/file.txt');
