I just installed pymongo from an .exe on a windows 7 box. I tried connecting to mongodb by:
import pymongo
c = pymongo.Connection()
i get the following error:
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
c = pymongo.Connection()
File "E:\Softwares\installed\Python2.7\lib\site-packages\pymongo\connection.py", line 370, in __init__
self.__find_master()
File "E:\Softwares\installed\Python2.7\lib\site-packages\pymongo\connection.py", line 605, in __find_master
raise AutoReconnect("could not find master/primary")
AutoReconnect: could not find master/primary
I did some googling and i figured that the mongodb daemon is not running and hence i'm not able to connect. I tried doing the following:
c = pymongo.Connection('localhost', 27017)
But i got the same error. How do i start the mongodb deamon ?? Or is there any other problem/error ??
Thanks in advance :)
Go to http://www.mongodb.org/downloads to download the version of mongodb for your operating system.
Unzip the downloaded folder.
Run the file mongod.exe. (This is in the "bin" folder)
You should now be able to connect using pymongo.

I am trying to use the grammar-check 1.3.1 library for Python
I have installed it using the pip commands
$ pip install --upgrade 3to2
$ pip install --upgrade language-check
I also unzipped the LanguageTool file from this link and moved it to C:\Users\me\AppData\Roaming\Python\Python27\site-packages\grammar_check
Then I tried to run a test program
import grammar_check
tool = grammar_check.LanguageTool('en-GB')
text = 'This are bad.'
matches = tool.check(text)
len(matches)
But I got this error:
Traceback (most recent call last):
File "grammar-checker-test.py", line 2, in <module>
tool = grammar_check.LanguageTool('en-GB')

raise Error(u'{}: {}'.format(cls._url, e))
grammar_check.Error: http://127.0.0.1:8081: HTTP Error 400: Bad Request
How can I solve this error?
I had this error:
grammar_check.Error: http://127.0.0.1:8081:
I am not sure why you have to start server on your local machine as this piece of code does exactly that:
tool = grammar_check.LanguageTool('en-GB')
If you will have one more language_tool server running on 8081, then it will try to start server on port 8082 and if even that is busy on 8083 and then will fail (which was happening in my case).
Anyways for my error, I had to debug a lot and finally figured out that server was not able to run as my JAVA runtime environment was messed up.
The problem was that I wasn't running the LanguageTool server.
In order to do that I have to check if I have the LanguageTool folder (its version must be < 3.3, in my case it's the 2.2) inside my grammar_check folder.
Then using the cmd shell I have to move into this LanguageTool folder, which in my case is located in this path:
C:\Users\me\AppData\Roaming\Python\Python27\site-packages\grammar_check\LanguageTool-2.2
than, I have to run the server with this command
java -cp languagetool-server.jar org.languagetool.server.HTTPServer --port 8081
and voilà grammar_check is working well

Edit on 12.10.2016
I use a Mac with macOS El Captain. I have the program "Parallels" on my laptop for using Access in a virtual machine. Python is installed on the Mac side.
What must I change that Python can use the ODBC interface to Access?
Edit 13.10.2016
I find a the toolkit "pyodbc" i think this should work on mac but again i can not ran the setup file i got the error. I already installed homebrew and find this dokumentation for installing (https://github.com/lionheart/django-pyodbc/wiki/Mac-setup-to-connect-to-a-MS-SQL-Server)
Error in python:
Traceback (most recent call last):
File "/Users/123GuteLaune/connectionprogramm.py", line 1, in

Reason: image not found
If you are running Python on the Mac side then you need to use a driver that is compatible with macOS. The Microsoft Access-Trebier (*.mdb) ODBC driver is a Windows DLL (ODBCJT32.DLL) and I doubt very much that the Mac version of Python can use it.

Already referred this , but i dont have any sleep in my code.
Not really sure what could go wrong.
Please let me know if I am missing something obvious.
The issue was with rabbitmqctl. Reconfigured it, Restarted service, and the issue is fixed.
Make sure rabbitmqctl is installed(if installed, uninstall it and re-install;when you just enter rabbitmqctl, it should display the help)
rabbitmqctl start_app
TIP: I tried installing first using 'brew',but for some reason, I was not able to get it right. So installed, rabbitmqctl as a separate package and added to PATH
Nettuts-fetch package stopped working. I followed 'Reverting to a Freshly Installed State' and then started to install packages. I started with Nettuts-fetch and re-started Sublime on each package install. The Nettuts-fetch worked fine until I installed SFTP. I removed SFTP and Nettuts-fetch worked again.
EDIT:
Fetch:file - works as expected.
Fetch:Package - I can select a download location, the process stalls for a while, but does not show download animation processes (equals sign moving side to side), the download file is created with nothing inside and there is not a download complete confirmation.
Is there an error log file I can look for?

I presume there is a conflict between these two packages though I can not find anything relating to this on the Web? I do not know how to debug any further - help appreciated.

I"m trying to get web2py running on an Ubuntu machine. All the docs seem to indicate that to run it on a *nix system, you download the source and do:
python web2py.py
I grabbed the source (stable source, not the trunk, version 1.99.4) and tried the above, but after entering a password for the server I get (in the terminal):

Any suggestions? I'm running Python 2.7.1+. I've read elsewhere that you also need pyschopg2 installed for web2py to run, and I've confirmed that this is in fact installed as well (I did a sudo apt-get install python-psycopg2 and got "python-psycopg2 is already the newest version").
I just downloaded and web2py runs ok in ubuntu, python 2.7.2+

Are you trying to run web2py on appengine environment?
Do you have SQLITE module working ok in your Python?
A possibility is permission issue, your user have permission to write to web2py/* folder?
It looks like a bug in web2py 1.99.4. I was having the same problem using Postgres and psycopg2, but in Windows.
I tried with 1.99.2 and it worked fine.
Actually, the bug seems to be related to the cryptic error message - 1.99.2 gave me the error message that the database doesn't exist, which was easily fixed. 1.99.4 does not mention the missing database. However, when I created the database and tried with 1.99.4, it worked fine.
