在node.js中处理相对路径的标准方法

Question

Node.js path resolve system make me mad. I have var a = '../data/data.db' path to a file but this path resolve differently depending from am I run this code from node.js directly or from test runner or from CI. Is there is a standard unified way how relative paths need to be managed in node.js?

Answer 1

You should use the __dirname property and path.resolve . __dirname gives you the path to the scripts location as opposed to the current execution location, and path.resolve cleans up the relative path.

var path = require('path');
var a = path.resolve(__dirname, '../data/data.db');

Answer 2

您可以使用诸如__dirname之类的全局变量，它指向当前正在执行的脚本所在的目录。
