【问题描述】:
我当前的代码如下所示:
const gzip2 = zlib.createUnzip();
const pack2 = new tar.Unpack();
const source2 = Readable.from('public/img.tar.gz');
const destination2 = fs.createWriteStream('public/images2');
pipeline(source2, gzip2, pack2, destination2, (err) => {
if (err) {
console.error('An error occurred:', err);
process.exitCode = 1;
}
});
但是我收到了这个错误:
internal/streams/pipeline.js:108
throw new ERR_INVALID_ARG_TYPE(
^
TypeError [ERR_INVALID_ARG_TYPE]: The "val" argument must be an instance of Readable, Iterable, or AsyncIterable. Received an instance of Unpack

}
我也试过
const pack2 = tar.extract();
没有运气。 如果有人可以帮助我使用管道提取此 tar 文件,那么我也可以解压缩该文件。我会很感激。我见过人们在网上使用 .pipe(tar.extract()) ,但我试图让我的代码尽可能的干净和统一。这个:https://www.npmjs.com/package/tar 很遗憾没有提供多大帮助。
