Error: invalid signature: 0x80014

It's just an ordinary zip file and node-unzip can't unzip.

@EvanOxfeld would you deprecate this project?

For those who encounter the same problem, here are some alternatives I found:

upzip file on disk:
https://github.com/hokein/node-minizip

unzip and ignore error:
https://github.com/alunny/zstream

I get a slightly different error: invalid signature: 0x4fcc0d08

If you're still having this issue, I've published unzip-stream which should solve it.

[felipeochoa]

@mhr3 Thanks! This solved the issue for me

@mhr3 I'm getting Error: Invalid signature in zip file in your lib too. Any ideas?

[mhr3]

@hiddenkirby Is it a zip64? Those are not supported. Otherwise should open a bug there - https://github.com/mhr3/unzip-stream/issues - ideally with the zip attached.

[hiddenkirby]

How does one determine if it's a zip64?

[mhr3]

For example mac's unzip tool wouldn't work.

[hiddenkirby]

Hrm. i was able to unzip on the mac. I will say i was able to use https://github.com/cthackers/adm-zip .. if that helps. I'm sorry i cannot provide the zip, but i wonder if size of the zip file matters?

[mhr3]

Only if the archive (or any of the files within) is >=2GB.

[hiddenkirby]

I would bet that was it.

[mhr3]

Also, what error exactly do you get from node-unzip? (if you can get that)

I have the same issue. I tried unzip-stream to see if it resolved my issue but no luck.

If it can help, here are the values I get when I put a breakpoint here https://github.com/mhr3/unzip-stream/blob/master/lib/unzip-stream.js#L84
chunk.readUInt32LE(0): 1329865020
LOCAL_FILE_HEADER_SIG: 67324752
CENTRAL_DIRECTORY_SIG: 33639248
CENTRAL_DIRECTORY_END_SIG: 101010256

Here, the chunk value should be equal to LOCAL_FILE_HEADER_SIG but it is not, so it default to 'Invalid signature' error.

The file works on mac with unzip and zip -T says everything is ok.
File size is 14274730.

Discolure: I don't anything about zip file binary format.

[mhr3]

1329865020 in hexadecimal is 0x4f44213c, which is ASCII for <!DO. Meaning you're passing plain text (looks like start of html/xml markup) to unzip.

Oh no. Thanks for the noticing this. The webpage I am downloading the script from is blocking the download if it's not a browser apparently...
