I know this is pretty old, and the original question I was responding to is marked as duplicate and directed here, but I ran into an issue trying to get jasmine-reporters to work and didn't like the idea that I had to downgrade in order for it to work. I found out that jasmine-reporters wasn't resolving the savePath correctly and was actually putting the reports folder output in jasmine-reporters directory instead of the root directory of where I ran gulp. In order to make this work correctly I ended up using process.env.INIT_CWD to get the initial Current Working Directory which should be the directory where you ran gulp. Hope this helps someone.

var reporters = require('jasmine-reporters');
var junitReporter = new reporters.JUnitXmlReporter({
  savePath: process.env.INIT_CWD + '/report/e2e/',
  consolidateAll: true,
  captureStdout: true
 });

Node.js 10支持ECMAScript模块，其中__dirname和__filename不再可用。

然后，要获得当前ES模块的路径，必须使用:

import { fileURLToPath } from 'url';

const __filename = fileURLToPath(import.meta.url);

对于包含当前模块的目录:

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

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

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.

这个命令返回当前目录:

var currentPath = process.cwd();

例如，使用路径读取文件:

var fs = require('fs');
fs.readFile(process.cwd() + "\\text.txt", function(err, data)
{
    if(err)
        console.log(err)
    else
        console.log(data.toString());
});

NodeJS公开了一个名为__dirname的全局变量。

__dirname返回JavaScript文件所在文件夹的完整路径。

因此，作为一个例子，对于Windows，如果我们用下面的行创建一个脚本文件:

console.log(__dirname);

然后使用以下命令运行脚本:

node ./innerFolder1/innerFolder2/innerFolder3/index.js

输出将是: C: \用户…<项目目录> \ innerFolder1 \ innerFolder2 \ innerFolder3
