尝试使用最新版本的tar，但是tar.Pack在使用tar 4.4.6版本时失败，并显示以下错误

Question

我正在尝试使该文件节点10兼容。节点10带有自己的4.4.6版本的tar，但是上面的代码是用tar 2.2.1编写的。该错误是因为以前使用的tar.Pack现在无法使用，因为它现在编写的方式不同于以前的方式。我只想使下面的代码节点10兼容，而不会破坏功能。如果有人知道如何请帮助。

var packer = tar.Pack({
                 ^

My code is here.

/**

 *
 * Note: ignores the cache directory and install-io.json
 *
 * @param dir {String} Path to the source directory
 * @param outfile {String} Path/filename to the output file

var fs = require('fs'),
    path = require('path'),
    zlib = require('zlib'),
    tar = require(path.join(node_env, './node_modules/tar')),
    fsignore = require(path.join(node_env, './node_modules/fstream-ignore')),
    ignores = {
        files: ['.ignore', '.gitignore'],
        rules: ['/cache/', 'install-io.json']
    },
    folder = process.argv[2],
    out = process.argv[3];

if (!folder) throw new Error('Require source directory');

folder = path.resolve(folder);

var folderStat = fs.statSync(folder);
if (!folderStat.isDirectory())
    throw new Error(util.core.format('[%s] is not a valid directory', folder));

console.log('Source directory: [%s]', folder);

// If out is not specified then use the source directory name.
out = out || process.cwd() + path.basename(folder);

if (path.extname(out) !== '.tgz') path += '.tgz';
out = path.resolve(out);

console.log('Output file to: [%s]', out);

var tgzStream = fs.createWriteStream(out),
    options = {
        path: folder
    };

tgzStream.on('close', function () {
    console.log('tgz stream closed');
});

tgzStream.on('error', function (err) {
    assert.ifError(err);
});

options.ignoreFiles = ignores.files;
options.follow = true;

var folderStream = fsignore(options);
folderStream.addIgnoreRules(ignores.rules, 'custom-rules');

folderStream.on('entry', function (e) {
    console.log('fstream entry: %s', e.path);
});
var packer = tar.Pack({
    noProprietary: true
});
folderStream.pipe(packer).pipe(zlib.Gzip()).pipe(tgzStream);

我正在使用节点10.13.0和tar 4.4.6。它与tar 2.2.1兼容。有没有解决办法？任何建议都会有所帮助。
