Can't start devpi-server on Amazon Linux 2015.09
I'm trying to install devpi-server on Amazon Linux 2015.09 but when I start it, I'm receiving the following error:
$ cat /etc/system-release Amazon Linux AMI release 2015.09 $ devpi-server --version 3.0.2 $ devpi-server --start 2016-03-22 21:53:12,909 INFO NOCTX Loading node info from /opt/devpi/.devpi/server/.nodeinfo 2016-03-22 21:53:12,910 INFO NOCTX generated uuid: 89e20f8f78fc4f2f8d8b96e121115993 fatal: The backend 'sqlite' can't be found, is the plugin not installed?
I am able to import sqlite3 from Python. $ python Python 2.7.10 (default, Dec 8 2015, 18:25:23) [GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

What am I missing?
How did you install devpi-server? It looks like it can't find the entry point for the plugin.
For me this happens during development when I checkout the source for devpi-server 3.x, install it in my virtualenv and then switch the repository to 2.x.

Cam you verify you are using the python interpreter which can import sqlite3 when starting devpi-server?

Could you check that lib/python2.7/site-packages/devpi_server/keyfs_sqlite_fs.py exists?
Also ``cat lib/python2.7/site-packages/devpi_server-3.0.2.dist-info/entry_points.txt`` should result in this:
``` [console_scripts] devpi-server = devpi_server.main:main
[devpi_server] devpi-server-auth-basic = devpi_server.auth_basic devpi-server-auth-devpi = devpi_server.auth_devpi devpi-server-sqlite = devpi_server.keyfs_sqlite devpi-server-sqlite-fs = devpi_server.keyfs_sqlite_fs
[devpi_web] devpi-server-status = devpi_server.views ```
Finally, check this:
``` % python Python 2.7.11 (default, Dec 23 2015, 08:32:32) [GCC 4.2.1 Compatible Apple LLVM 7.0.2 (clang-700.1.81)] on darwin Type "help", "copyright", "credits" or "license" for more information.

Glad it worked out for you. I hope to use the information gathered by this to improve the error reporting.

I have just had this issue while setting 2+ servers. The symptoms were:
- First server setup fine - 2nd 3rd etc server would install devpi-server but in running it I would get this sqlite error. - Ran debug mode and even strace but nothing obvious
With much troubleshooting, I found that I was installing devpi-server using the first server (-i http://first.server.local) When I removed that and let pip use the public servers I had to add the --upgrade switch and I got this.
Installing collected packages: setuptools
Found existing installation: setuptools 0.6rc11
Uninstalling setuptools-0.6rc11:
Successfully uninstalled setuptools-0.6rc11 Successfully installed setuptools-21.1.0
All other packages were at their latest versions.
I thought I would report this back.
