使用path模块的basename方法:

var path = require('path');
var filename = path.basename(__filename);
console.log(filename);

下面是上面例子的文档。

正如Dan指出的，Node正在处理带有“——experimental-modules”标志的ECMAScript模块。节点12仍然支持前面提到的__dirname和__filename。

如果您正在使用——experimental-modules标志，还有另一种方法。

另一种方法是获取当前ES模块的路径:

import { fileURLToPath } from 'url';
const __filename = fileURLToPath(new URL(import.meta.url));

对于包含当前模块的目录:

import { fileURLToPath } from 'url';
import path from 'path';

const __dirname = path.dirname(fileURLToPath(new URL(import.meta.url)));

我又看了一遍文件后找到的。我要找的是__filename和__dirname模块级变量。

__filename是当前模块的文件名。这是当前模块文件的解析绝对路径。(例:/ home /凯尔/一些/ dir / file.js) __dirname是当前模块的目录名。(例:/ home /凯尔/一些/ dir)

你可以使用process.env.PWD来获取当前应用程序的文件夹路径。

当涉及到主脚本时，它非常简单:

process.argv[1]

来自Node.js文档:

process.argv 包含命令行参数的数组。第一个元素是“node”，第二个元素是JavaScript文件的路径。下一个元素将是任何额外的命令行参数。

如果你需要知道模块文件的路径，那么使用__filename。

如果你想在shell脚本中使用类似$0的东西，试试这个:

var path = require('path');

var command = getCurrentScriptPath();

console.log(`Usage: ${command} <foo> <bar>`);

function getCurrentScriptPath () {
    // Relative path from current working directory to the location of this script
    var pathToScript = path.relative(process.cwd(), __filename);

    // Check if current working dir is the same as the script
    if (process.cwd() === __dirname) {
        // E.g. "./foobar.js"
        return '.' + path.sep + pathToScript;
    } else {
        // E.g. "foo/bar/baz.js"
        return pathToScript;
    }
}

如果你使用pkg来打包你的应用，你会发现这个表达式很有用:

appDirectory = require('path').dirname(process.pkg ? process.execPath : (require.main ? require.main.filename : process.argv[0]));

process.pkg tells if the app has been packaged by pkg. process.execPath holds the full path of the executable, which is /usr/bin/node or similar for direct invocations of scripts (node test.js), or the packaged app. require.main.filename holds the full path of the main script, but it's empty when Node runs in interactive mode. __dirname holds the full path of the current script, so I'm not using it (although it may be what OP asks; then better use appDirectory = process.pkg ? require('path').dirname(process.execPath) : (__dirname || require('path').dirname(process.argv[0])); noting that in interactive mode __dirname is empty. For interactive mode, use either process.argv[0] to get the path to the Node executable or process.cwd() to get the current directory.
