ERROR:raysync:pysqlite or sqlite3 must be installed.
Try opening up a python shell and running:

```
from peewee import sqlite3
print sqlite3
```

You can also try:

```
from pysqlite2 import dbapi2
import sqlite3
```

What happens? My python is compiled by myself, I forget to add sqlite3 module.
The peewee i used , running ok on windows, but linux. it print `ERROR:pysqlite or sqlite3 must be installed.`
