The compressed file cannot be decompressed by lzma command on Mac OS

I’m using LZMA-JS on nodejs, my code is as below

var my_lzma = require("lzma");
var fs = require('fs');

var result = my_lzma.compress('123456789qwertyuiop');
fs.writeFileSync('b.txt', new Buffer(result, 'ascii'), null, 'b');

then, I renamed “b.txt” to “b.txt.lzma” and tried to use lzma command to decompress it. but I only get the error message

lzma: b2.txt.lzma: Compressed data is corrupt

LZMA-JS and lzma command both are based on the same algorithm, from my understanding, lzma can decompress the file that is compressed by LZMA-JS, am I right? So could you please help me to find out the problem that why the file get decompressed failed? Thanks

I’m late to the party but you can do this:

const lzmajs = require('lzma');
lzmajs.LZMA().disableEndMark = true;
// ... do your stuff

I’d prefer not to do anything without @nmrugg’s input but I think LZMA-JS is wrongly writing the end-of-payload marker to the compressed stream even though the compressed size is known. That should not be allowed according to the docs (ref), and commenting out the call to $WriteEndMarker seems to solve this problem.
