I'm hoping that someone here can point me in the right direction with
freezing my Flask application. I'm using the latest git
version: 2.1dev-d649f53 (But it fails on 2.0 as well). I'm on a Mac using
10.7.5 and Python 2.7.
Note that to get to this point I had to do 2 things:
1) Change werkzeug lazy imports in __init__.py to be normal imports
2) Add an empty __init__.py module to flaskext so that the babel extension
is detected
Here is the output I get from PyInstaller:

*LookupError: no codec search functions registered: can't find encoding*
Here is the application:
from flask import Flask
from flaskext.babel import Babel, format_datetime
from datetime import datetime
from mypackage.database import MyDatabase
app = Flask(__name__)
bab = Babel(app)
class DemoDatabase(MyDatabase):
def set_connection_parameters(self):
self.connection_uri = 'postgresql://[email protected]/Demo'
self.engine_options['echo'] = True
db = DemoDatabase()
db.init()
@app.teardown_request
def shutdown_session(exception=None):
db.session_remove()
@app.route('/')
def root():
return u"Hello (Frozen) World!"
@app.route('/users')
def user_list():
columns = [User.first_name, User.last_name]
response = u""
users = db.session.query(*columns)
for user in users:
response += u"<br>" + user.first_name + " " + user.last_name
return response
@app.route('/date')
def date():
return u"Hello (Frozen) World! It is
{0}".format(format_datetime(datetime.now()))
if __name__ == '__main__':
app.run()
I can't quite pin down which area is causing this error, or where to start
looking. The application uses SQLAlchemy, Dogpile.cache, and PyCrypto 3rd
party packages (the rest are all from the standard library). What's
interesting is that if I run an app using my package, but not Flask-Babel,
then it works:
from flask import Flask
from mypackage.database import MyDatabase
from mypackage.models import User
app = Flask(__name__)
class DemoDatabase(MyDatabase):
def set_connection_parameters(self):
self.connection_uri = 'postgresql://[email protected]/Demo'
self.engine_options['echo'] = True
db = DemoDatabase()
db.init()
@app.teardown_request
def shutdown_session(exception=None):
db.session_remove()
@app.route('/')
def root():
return u"Hello (Frozen) World!"
@app.route('/users')
def user_list():
columns = [User.first_name, User.last_name]
response = u""
users = db.session.query(*columns)
for user in users:
response += u"<br>" + user.first_name + " " + user.last_name
return response
if __name__ == '__main__':
app.run()
It also works using Flask-Babel, but not my package:
from datetime import datetime
from flaskext.babel import Babel, format_datetime
from flask import Flask
app = Flask(__name__)
Babel(app)
@app.route('/')
def root():
return u"Hello (Frozen) World! It is
{0}".format(format_datetime(datetime.now()))
if __name__ == '__main__':
app.run()
So it is just some combination of Flask-Babel and something in my package
that is causing some kind of conflict. Any help or traceback deciphering
would be greatly appreciated!
