bad marshal data error about pyconcrete HOT 7 CLOSED

@Zoeybird which python version in your environment?

from pyconcrete.

I also got this error, my python ver is 2.7.9

from pyconcrete.

Reference by stackoverflow thread
It's seems caused by build & run by different python version
ex: build .pye by python 2.7.8, run .pye by python 2.7.9

@fangchih Please help to make sure build & run on same python version
Or you can rebuild all .pye, and try again

from pyconcrete.

@Falldog thanks, I just found the root cause same as you said.

have any workaround on this? because the PROD's python is older than CI's python.

Seems different platform will cause this issue too, still checking...

from pyconcrete.

1. The easiest way is that make sure all python version sync.
2. Use Vagrant or docker to process CI task to make sure python version is sync in VM env
3. Production environment is hard to control the python version, maybe you should try PyInstaller rather than pyconcrete

@fangchih I don't know how your Production or CI work
Maybe you can explain more detail then I can give you more suggestion.

@Falldog, thanks for your help...

My PROD is embedded linux box which have 32bit and 64bit os, so far we only have 2.7.9 because of our toolchian limitation.

My approach now is use docker in CI to emulate PROD env, same as you mentioned.
I will also give PyInstaller a try, but seems pycontrete is more light weight to just meet my requirement. XD

@fangchih, sounds great!
:)

@Zoeybird I will close this issue, cause the root cause should be run & build by different python version. If there is another root cause of the issue, you can reopen it.
