I'm trying to package a CLI app as a Linux standalone executable using PyInstaller. I don't have a Linux OS so I used Vagrant to package it; used the CentOS 7 box since the server where the executable will run is also CentOS 7.
I was able to create a standalone executable and it ran successfully with a fresh CentOS 7 Vagrant machine (no provisioning scripts / no python3 and its dependencies installed). But when I run the executable in the server, it gives me this error: [user@server ~]$ emails_automation/emails --help [22874] Error -3 from inflate: unknown compression method [22874] Error decompressing _asyncio.cpython-38-x86_64-linux-gnu.so Failed to write all bytes for _asyncio.cpython-38-x86_64-linux-gnu.so fwrite: Bad address Some Observations ✅ Both VM and the actual server has the same glibc version: VM: [root@localhost emails]# ldd --version ldd (GNU libc) 2.17 Server: [user@server ~]$ ldd --version ldd (GNU libc) 2.17 🤔 Searching for "inflate: unknown compression method" in the pyinstaller repo and returned files related to `zlib`. So I checked whether zlib is installed in the server, and the fresh CentOS 7 VM (the one without any provisioning scripts) by running the python REPL and both doesn't give import errors which tells me zlib is installed.
