django | gunicorn | ImportError: No module named _

问题:

Configured and installed python2.7 as below:

./configure --enable-shared --with-ssl
make
install

And then install gunicorn with command python setup.py install.

Installation went well without any problem but now when I am running

gunicorn django.wsgi:application

I am getting below error.What should I do to move forward?

   Error: class uri 'sync' invalid or not found:

I assume that you are using a Linux distro since you compiled python from source. You need at least 2 SSL library: openssl and openssl-devel

With Ubuntu: apt-get install openssl openssl-devel

With Redhat based: yum install openssl openssl-devel

To build from source, you can download from: openssl and openssl-devel

Hope it helps.
