I am in the process of learning the RobotFramework from an absolute beginners point.
I have had experience creating automation scripts using ruby-watir and gherkin. As well as automation in c#.
However I am simply stumped with even the setup of RobotFramework in Pycharm.
I have installed all the packages
I deemed necessary
-including selenium/RobotFramework /RobotFramework-selenium2library.
My Python.exe and scripts are in the correct directory as well as the environment variables being added.
However when I run :
from lettuce import *
from behave import *
from Selenium import webdriver
#step("I am on the web")
def step_impl(context):
context.browser = webdriver.Firefox
pass
I get:
Traceback (most recent call last):
File "C:/Users/Jordan/PycharmProjects/RbtFrameWork/features/steps/Test_steps.py", line 3, in <module>
from Selenium import webdriver
ImportError: No module named Selenium
I imagine it's something to do with the installation location of my selenium - which I have installed through pip
Any help?
Python is case sensitive so instead of from Selenium import webdriver you should use from selenium import webdriver

The question I have - can you use Firestore Native mode on Google App Engine Standard using Python 2.7? I need GAE- Standard because we are using Google Endpoint that is not support on GAE-Flex.
The doc here says App Engine Client library integration is not supported on Python2.7 GAE Standard environment. But I am not trying App Engine Client library, I am trying App Engine Server library in GAE Standard Environment.
How do I solve for import error for cygrpc? The solution here, says -
python -m pip install grpcio --ignore-installed
Is this recommended?
It's 2020, and you can now use grpcio (without explicitly adding it yourself as it's a built-in library) w/Cloud Firestore natively on App Engine with Python 2.7. Three things to make this work:
Add google-cloud-firestore to your requirements.txt file and install with pip install -U -t lib -r requirements.txt.
Add these lines to the libraries section of your app.yaml file:
libraries:
- name: grpcio
version: 1.0.0
- name: setuptools
version: 36.6.0
Ensure these lines are in your appengine_config.py file:
import pkg_resources
from google.appengine.ext import vendor
# Set path to your libraries folder.
path = 'lib'
# Add libraries installed in the path folder.
vendor.add(path)
# Add libraries to pkg_resources working set to find the distribution.
pkg_resources.working_set.add_entry(path)
Of course, we do recommend you eventually migrate to Python 3 to take advantage of the greater flexibility the next generations (of Python and App Engine) provide, esp. the ability to tap into other GCP services. However, caveat such a port isn't without effort if your app is complex & deeply-dependent on App Engine's 1st gen built-in services. Most of the suggestions above are derived from this section of the migration docs.
Once you're on Python 3, everything related to 3P libraries on App Engine becomes much easier, as I demonstrate in this other SO answer.
A while ago GRPC wasn't supported on GAE standard, see GRPC and types import error in App Engine Datastore. I didn't try since, but I don't see newer activity on issue 149.
Also the cython reference in the traceback suggests that it may include compiled code, which would violate the pure python standard environment sandbox restrictions that applies to the code you deploy.
Make sure that your installed python version bit(32/64) and your system bit(32/64) are matched.
If they are not matched please follow the solution mentioned at https://azurelessons.com/cannot-import-name-cygrpc/
I created an Odoo Module in Python using the Python library ujson.
I installed this library on my development server manually with pip install ujson.
Now I want to install the Module on my live server. Can I somehow tell the Odoo Module to install the ujson library when it is installed? So I just have to add the Module to my addons path and install it via the Odoo Web Interface?
Another reason to have this automated would be if I like to share my custom module, so others don't have to install the library manually on their server.
Any suggestions how to configure my Module that way? Or should I just include the library's directory in my module?
You should try-except the import to handle problems on odoo server start:
try:
from external_dependency import ClassA
except ImportError:
pass
And for other users of your module, extend the external_dependencies in your module manifest (v9 and less: __openerp__.py; v10+: __manifest__.py), which will prompt a warning on installation:
"external_dependencies": {
'python': ['external_dependency']
},
Big thanks goes to Ivan and his Blog
Thank you for your help, #Walid Mashal and #CZoellner, you both pointed me to the right direction.
I solved this task now with the following code added to the __init__.py of my module:
import pip
try:
import ujson
except ImportError:
print('\n There was no such module named -ujson- installed')
print('xxxxxxxxxxxxxxxx installing ujson xxxxxxxxxxxxxx')
pip.main(['install', 'ujson'])
In python file using the following command, you can install it (it works for odoo only). Eg: Here I am going to install xlsxwriter
try:
import xlsxwriter
except:
os.system("pip install xlsxwriter")
import xlsxwriter
The following is the code that is used in odoo base module report in base addons inside report.py (odoo_root_folder/addons/report/models/report.py) to install wkhtmltopdf.
from openerp.tools.misc import find_in_path
import subprocess
def _get_wkhtmltopdf_bin():
return find_in_path('wkhtmltopdf')
try:
process = subprocess.Popen([_get_wkhtmltopdf_bin(), '--version'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
except (OSError, IOError):
_logger.info('You need Wkhtmltopdf to print a pdf version of the reports.')
basically you need to find some python code that will run the library and install it and include that code in one of you .py files, and that should do it.
I am trying to install SQLAlchemy on a Windows 8 64 bit machine for Python 2.7
When I run the setup.py file that comes with the download from the SQLAlchemy site, a .egg file called 'SQLAlchemy-1.0.0-py2.7.egg' is placed in C:\Python27\Lib\site-packages.
But when I try to do a basic import of the library using an import statement on given in the SQLAlchemy documentation, I get an error message.
The import code is:
from flask.ext.sqlalchemy import SQLAlchemy
And the error message I get is:
c:\Users\Me\MyCode>ws_dbwrite.py
Traceback (most recent call last):
File "C:\Users\Me\MyCode\ws_dbwrite.py", line 2, in <module>
from flask.ext.sqlalchemy import SQLAlchemy
File "C:\Python27\lib\site-packages\flask-0.10.1-py2.7.egg\flask\exthook.py",
line 87, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.sqlalchemy
Should I be going about installation in a different manner? Or should the .egg file for SQLAlchemy go at a different file level? Or am I missing something obvious here?
Edit: If I change the import line to just
import SQLAlchemy
The import works, but Python does not recognize things like
db = SQLAlchemy(app)
as valid commands.
You have installed SQLAlchemy, but you are trying to use the Flask extension, Flask-SQLAlchemy. While the two are related, they are separate libraries. In order to use
from flask.ext.sqlalchemy import SQLAlchemy
you need to install it first.
pip install Flask-SQLAlchemy
(You installed SQLAlchemy directly from source. You can also do that for Flask-SQLAlchemy.)
I am new to programming and have recently installed the Enthought Canopy distribution and can't seem to import certain modules.
Python 2.7 MacOSX
Numpy works when I import it, however other modules which I have created or downloaded as a simple module.py file return this error message:
import numfun1
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-297-cb46e477a372> in <module>()
----> 1 import numfun1
ImportError: No module named numfun1
Could it have something to do with where those modules are saved? If so, how do I point python in their direction? or where should I put those modules so that Python sees them.
Thank you in advanced for your suggestions.
Information about the module search path is included in the official Python tutorial: http://docs.python.org/2/tutorial/modules.html#the-module-search-path.
A lot of python libraries come with a setup.py script that will automatically install them into locations that are on the search path.
The installation process can be even more automated by using a Python package manager like pip.
If you create a module you must put it where your script is.
I am trying to setup django with fastcgi on apache. Django is installed and seems to be running correctly but I am having problems with setting up fastcgi.
I decided to test out my dispatch.fcgi script in the interactive python shell line by line and the following line:
from django.core.servers.fastcgi import runfastcgi
results in the following error:
ImportError: No module named core.servers.fastcgi
I can import django with no problem but import django.core gives yet another ImportError (No module named core).
How can I go about ensuring that I can import django.core. If I can import django then in must be on my path, and so why can I not import core?
You probably have a file/folder called django somewhere in your path, that isn't the actual path.
try this
import sys
sys.path
And then check everything in that output to see if there is a file/folder called django(.py) somewhere.
If so, change the path (sys.path = ['/path/to/directory/below/django/install'] + sys.path) or move/rename the file.
Probably you have django.py module in your working directory or in any other that is in python path.
For anyone having this problem and coming across this question like I did, it turns out that fastcgi support has been removed as of Django 1.9, thus you will get this import error if trying to import it. Refer Using Django with virtualenv, get error ImportError: No module named 'django.core.servers.fastcgi'
