如何使用node处理unix路径？

const path = require('path');

const filePath = '/usr/local/bin/node';
const pathObj = path.parse(filePath);

console.log(pathObj);
// 输出：{ root: '/', dir: '/usr/local/bin', base: 'node', ext: '', name: 'node' }

const path = require('path');

const dir = '/usr/local';
const file = 'bin/node';
const filePath = path.join(dir, file);

console.log(filePath);
// 输出：/usr/local/bin/node

const path = require('path');

const filePath = '/usr//local/../bin/node';
const normalizedPath = path.normalize(filePath);

console.log(normalizedPath);
// 输出：/usr/bin/node

const path = require('path');

const filePath = '/usr/local/bin/node';

console.log(path.dirname(filePath));
// 输出：/usr/local/bin

console.log(path.basename(filePath));
// 输出：node

console.log(path.extname(filePath));
// 输出：''
