Sentry run web command uwsgi segfault


#1

Hi,
I am trying to install sentry on one of a server, following this guide,
/server/installation/python/

But when I try to start the server, I got this error segfault while doing this command
sentry --config ./ run web

I do not have any ideas what might cause this kind of segfault @@
Machine is on centos 6.5 (but i think it’s not quite an issue)

Ive never seen this issue before, but I can say we don’t support CentOS.


#3

Ah maybe the python package i used has some error, tried another python package and it seems working well now
