Error -3 from inflate: unknown compression method

[paxcodes]

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 both the server and the fresh CentOS 7 VM (the one without any provisioning scripts). I ran the python REPL and both doesn't give import errors which tells me zlib is installed.

VM:

[vagrant@localhost ~]$ python
Python 2.7.5 (default, Apr  2 2020, 13:16:51) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import zlib
>>> zlib.crc32
<built-in function crc32>

Server:

[user@server ~]$ python
Python 2.7.5 (default, Nov 16 2020, 22:23:17) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import zlib
>>> zlib.crc32
<built-in function crc32>

What could be causing this? I know that PyInstaller doesn't do cross-compilation. Is it because I'm using a virtual machine to package it?
