I'm trying to run python setup.py a small script on a Linode instance where I'm running Flask + sqlalchemy (mysql).
#filename - setup.py
from daaru import db
def init_db():
db.drop_all()
db.create_all()
init_db()
This is the error I'm getting -

ImportError: No module named MySQLdb
The funny part is that when I log into the server, activate the virtual env (named v1), and run init_db in ipython everything works as expected. But when I run it as a script, it gives me an ImportError for the module named MySQLdb. MySQLdb has a systemwide installation using apt-get install python-mysqldb as this package is not available via pip.
What am I doing wrong here?
Running pip freeze on the server shows me this:
Flask==0.9
Flask-SQLAlchemy==0.16
Jinja2==2.6
SQLAlchemy==0.7.9
Werkzeug==0.8.3
argparse==1.2.1
wsgiref==0.1.2
Is the error coming because mysqldb package is not found in the venv? Why isn't then the systemwide installation of that package being used?
I used this blog post to install mysql-python in my venv. Everything works likes a charm now. Thanks.
I've also added a fabfile to automate deployment -
from fabric.api import *
env.user = "host"
env.hosts = ["hostname"]
env.directory = "/home/captain/public/daaru"
env.activate = "source /home/captain/public/daaru/v1/bin/activate"
def deploy():
with cd(env.directory):
run("git pull")
run("sudo service apache2 reload")
def virtualenv(command):
with cd(env.directory), prefix(env.activate):
run(command)
def populate_db():
virtualenv("python setup.py")
def freeze():
""" command for testing virtualenv """
virtualenv("pip freeze")
I just ran into this, and the simple, dirty workaround for me was to cp -r /usr/lib/python2.7/dist-packages/*mysql* $VIRTUALENV/lib/python2.7/dist-packages/ and cp -r /usr/lib/python2.7/dist-packages/*MySQL* $VIRTUALENV/lib/python2.7/dist-packages/, which picked up all needed parts.
Looking into it more it turned out that pip install MySQL-python failed in the virtualenv due to libmysqlclient-dev not being installed via apt. Hope this helps.

I am having issues with connecting Amazon AWS MySQL with SQLAlchemy. According to the instruction, I have connected.
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://<user>:<password>#<host>/<dbname>

I am using Python3.7 version. Even according to the stackoverflow, I have installed pymysql, but still facing the problem.
Thank you for your reply.
If you use the PyMySQL client to connect to MySQL, your SQLAlchemy connection string needs to start with
mysql+pymysql://
instead of mysql://.
If you connect with mysql:// then you will need to install the MySQLdb library as shown in the Traceback.
Above issues has been solved with the following:
import pymysql
pymysql.install_as_MySQLdb()
Nothing to change anywhere.
Step 1
If you want to use MySQLDB you need to use one of the following commands. Which one depends on what OS and software you have and use.
easy_install mysql-python (mix os)
pip install mysql-python (mix os/ python 2)
pip install mysqlclient (mix os/ python 3)
apt-get install python-mysqldb (Linux Ubuntu, ...)
cd /usr/ports/databases/py-MySQLdb && make install clean (FreeBSD)
yum install MySQL-python (Linux Fedora, CentOS ...)
For Windows, see this answer: Install mysql-python (Windows)
Step 2:
Create Engine
engine = create_engine('mysql+mysqldb://...', pool_recycle=3600)
use the create_engine.pool_recycle option which ensures that a connection will be discarded and replaced with a new one if it has been present in the pool for a fixed number of seconds:
Create Connection object
conn = engine.connect()
Execute SQL queries
conn.execute("SELECT * From table;")
I have defined a few different Cloud Dataflow jobs for Python in the Google AppEngine Flex Environment. I have defined my requirements in a requirements.txt file, included my setup.py file, and everything was working just fine. My last deployment was on May 3rd, 2018. Looking through logs, I see that one of my jobs began failing on May 22nd, 2018. The job fails with a stack trace resulting from a bad import, seen below.

from google.iam.v1.logging import audit_data_pb2
ImportError: No module named logging
So the main issue seems to come from the pubsub dependency relying on importing google.iam.v1.logging, which is installed from grpc-google-iam-v1.
Here is my requirements.txt file
Flask==0.12.2
apache-beam[gcp]==2.1.1
gunicorn==19.7.1
google-cloud-dataflow==2.1.1
google-cloud-datastore==1.3.0
pytz
google-cloud-pubsub
google-gax
grpc-google-iam-v1
googleapis-common-protos
google-cloud==0.32
six==1.10.0
protobuf
I am able to run everything locally just fine by doing the following from my project.
$ virtualenv --no-site-packages .
$ . bin/activate
$ pip install --ignore-installed -r requirements.txt
$ python main.py
No handlers could be found for logger "oauth2client.contrib.multistore_file"
INFO:werkzeug: * Running on http://0.0.0.0:8080/ (Press CTRL+C to quit)
INFO:werkzeug: * Restarting with stat
No handlers could be found for logger "oauth2client.contrib.multistore_file"
WARNING:werkzeug: * Debugger is active!
INFO:werkzeug: * Debugger PIN: 317-820-645
specifically, I am able to do the following locally just fine
$ python
>>> from google.cloud import pubsub
>>> import google.iam.v1.logging
>>> google.iam.v1.logging.__file__
'/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/google/iam/v1/logging/__init__.pyc'
So I know that the installation of the grpc-google-iam-v1 package is working just fine locally.. the required files are there.
My questions are
Why is the install of grpc-google-iam-v1 on the Google AppEngine Flex Environment not installing all of the files correctly? I must be missing the /site-packages/google/iam/v1/logging directory.
Why would this randomly start failing? I didn't do any more deploys, the same code was running and working on the 21st and then it broke on the 22nd on May.
I was able to get the pipeline running again after changing the requirements.txt file to
Flask==0.12.2
apache-beam[gcp]
google-cloud-dataflow
gunicorn==19.7.1
google-cloud-datastore==1.3.0
pytz
google-cloud-pubsub
google-gax
grpc-google-iam-v1
googleapis-common-protos
google-cloud==0.32
six==1.10.0
protobuf
so simply removing the version requirements from apache-beam[gcp] and google-cloud-dataflow did the trick.
Building on the solution provided by John Allard, removing the version from the requirements.txt will automatically default to the latest version. Thus, with no version specified for apache-beam[gcp] , google-cloud-dataflow and google-cloud-pubsub they will all run on the latest version and solve the dependency issue. The requirements.txt will look like the following:
Flask==0.12.2
apache-beam[gcp]
gunicorn==19.7.1
google-cloud-dataflow
google-cloud-datastore==1.3.0
pytz
google-cloud-pubsub
google-gax
grpc-google-iam-v1
googleapis-common-protos
google-cloud==0.32
six==1.10.0
protobuf
When I try to import non-standard modules into my Flask app with debug mode on and run it locally, the Flask server crashes with an ImportError for _tkinter. If I remove the import for the non-standard module, or turn off debug mode, everything works as expected.
Examples
The following runs fine, and "Hello, World" can be seen at localhost:5000
from flask import Flask
app = Flask(__name__)
#app.route("/")
def home():
return "Hello, World"
if __name__ == '__main__':
app.run(debug=True)
If I add the following line at the top of the file
import dateparser
I get the following Traceback when I run the file:

raise ImportError, str(msg) + ', please install the python-tk package'
ImportError: No module named _tkinter, please install the python-tk package
For confirmation, with debug mode turned off everything runs as expected, even if I use the dateparser module. For example, the following shows "2015-01-01 00:00:00"
import dateparser
from flask import Flask
app = Flask(__name__)
#app.route("/")
def home():
return str(dateparser.parse("1 jan"))
if __name__ == '__main__':
app.run()
Importing any standard Python modules, such as
import json
works fine. But any other modules installed through pip cause the same issue.
If I run (as prompted by the error)
sudo apt-get install python-tk
Then the Traceback is replaced with an ImportError for _winreg

I just tried running the following code on my Windows 10 machine and it worked fine for me.
Flask-Test.py

app.run(debug=True)
I think there may be an issue with the python environment that you're currently working in. Perhaps try creating a virtual environment to operate out of using virtualenv to make sure that your environment is setup correctly.
If you would like to following along with the steps that I took to setup up a virtual environment to test the code, see below. The commands used might be slightly different when running from Ubuntu.
pip install virtualenv
Navigate to the folder where you have your test code saved and create the Virtual Environment using the following command
virtualenv env
Activate the virtual environment by navigating to the 'activate' file. In my case it was located at
.\venv\Scripts\activate
Download Flask and dateparser using pip
pip install Flask
pip install dateparser
Finally, activate the test file through the virtual environment
python .\Flasky-Test.py
Navigating to localhost returned a value of 2015-01-01 00:00:00 for me ok.
Edit
I just tried running your list of packages and managed to replicate the error that you were receiving. I believe the problem might be with the version of six that you are using. Try running
pip install six --upgrade
And let me know if that fixes the problem for you - it did for me.

ImportError: No module named pylons.util
I'm not sure how to proceed, any ideas?
ImportError: No module named pylons.util looks like Python cannot find the Pylons package, one of the Python packages that CKAN depends on. Two possibilities come to mind:
Did you activate your CKAN virtualenv, before running the paster command? ~/ckan/default/bin/activate.
Have you installed the Python packages that CKAN depends on into your virtualenv? With the virtualenv activated run pip install -r ~/ckan/default/src/ckan/requirements.txt
If you activate your CKAN virtual environment and then run pip freeze | grep pylons, this should tell you whether pylons is installed in the virtualenv.
The Distribution already installed: at the top of your terminal output is strange.
I had the same error and a slightly different solution:
got the error only after using sudo, so I went out of it (sudo -k)
then I got the following error: IOError: [Errno 13] Permission denied: '/etc/ckan/default/development.ini'
after digging around a lot, I finally found out that while the /etc/ckan had correct permissions, it was actually a symlink to ~/ckan/etc and that folder did not have correct permissions
I ran sudo chown -R `whoami` ~/ckan/etc and followed up with paster make-config ckan /etc/ckan/default/development.ini

I'm the maintainer of the package, thanks to your post I realized that we were missing celery/django-celery in our requirements. It's now added in the latest version.
So "pip install django-audiofield" will install those dependencies for you.
If you have django-audiofield already installed you can run the following command to upgrade : "pip install django-audiofield --upgrade"
Have you installed celery? If no, install celery (pip install celery). If the github application in question (a link would have been nice) has a requirements.txt file anywhere, do pip install -r requirements.txt to install all the required dependencies of the application.
If yes, it looks like your import search path may not be set up correctly to find Celery - just a guess based on the import error.
Open up the django shell (type python manage.py shell when you're in your project's working directory) and type in import sys; print sys.path. Make sure that Celery is installed in one of those directories, since sys.path specifies the import search path for python modules.
If it isn't included there, you can temporarily append the directory celery is installed into by doing sys.path.append("<directory where celery is>") (mind the backslashes, since you're on Windows). If, after doing that, you can successfully from celery.tasks import Task, then you can set the PYTHONPATH environment variable appropriately to make it permanent.
Also, since you installed Celery into a virtualenv, it may be worth checking that both django and Celery are in the same virtualenv.
Finally, the latest commits to Celery indicate Celery now has native Django support, but since that hasn't been released as a stable version yet, you may want to look at django-celery.
Edit (in response to comment below):
Since you mentioned you're trying to get django-audiofield to work: it seems to be on pypi. This means you can use pip (or easy_install) to install it using pip install django-audiofield once you've installed all the required (non-python) dependencies, and stuff like celery should be downloaded for you.
