Error in AWS Lambda when using pyzstd module

I'm trying to use module pyzstd on Lambda service, but I get the following error:

pyzstd module: Neither C implementation nor CFFI implementation can be imported. If pyzstd module is dynamically linked to zstd library, make sure not to remove zstd library, and the run-time zstd library's version can't be lower than that at compile-time.

I've installed this library locally on Macbook M1 using command pip install pyzstd. Then I zipped site-packages from venv and uploaded it along side with handler code.

Solution

  • The .so binary file was compiled for M1 & macOS. If you run it on other architecture/OS, it will fail to import.
