I tried downloading the latest NLTK release, and moving the nltk directory included in the zip file to my python project's working directory. Then I tried calling import nltk. Usually, to the best of my understanding, this would work - but I got this error:
Traceback (most recent call last):
File "/home/akf/PycharmProjects/comrad/main.py", line 32, in <module>
import plugins.nltk as plugins_nltk
File "/home/akf/PycharmProjects/comrad/plugins/nltk/__init__.py", line 89, in <module>
from nltk.internals import config_java
ImportError: No module named nltk.internals
It's accurate, I can't find this file either. What's the best way to do this?
For some libs, simply downloading the folder isn't going to work. You need more than just downloading it to actually install it, and before installing it make sure you have dependencies like numpy first.
Also managing dependencies with something like pip is better, you can track versions, upgrade etc, without having to manually removing and re-downloading the folder.
Seems you're working on Linux or UNIX? Here is a guide on how to install it http://www.nltk.org/install.html

I'm trying to use w3af to start doing some routine security testing on a webapp that I'm using. Install instructions recommend cloning a git repo, then running the python code and seeing what dependencies are unmet then installing them. My first run yielded:
ModuleNotFoundError: No module named 'ConfigParser
OK, no problem, right?
$ pip install ConfigParser
Collecting ConfigParser
Downloading configparser-5.2.0-py3-none-any.whl (19 kB)
Installing collected packages: ConfigParser
Successfully installed ConfigParser-5.2.0
Mission accomplished, let's try again!
$ ./w3af_console
Traceback (most recent call last):
File "./w3af_console", line 12, in <module>

ModuleNotFoundError: No module named 'ConfigParser'
Hmmm. Could swear we took care of that. Let's run pip (maybe pip3?) again to be sure?
$ pip3 install ConfigParser
Requirement already satisfied: ConfigParser in /Users/westonx/.pyenv/versions/3.8.2/lib/python3.8/site-packages (5.2.0)
Seems good. Let's check to see if the import path includes that directory:
$ python -c "import sys; print('\n'.join(sys.path)); import ConfigParser;"
/Users/westonx/.pyenv/versions/3.8.2/lib/python38.zip
/Users/westonx/.pyenv/versions/3.8.2/lib/python3.8
/Users/westonx/.pyenv/versions/3.8.2/lib/python3.8/lib-dynload
/Users/westonx/.pyenv/versions/3.8.2/lib/python3.8/site-packages
Traceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'ConfigParser'
So... we know the sys.path includes the directory pip says the module is installed in, but when we import it, python insists it's not there.
configparser-5.2.0.dist-info and configparser.py are indeed in my ~/.pyenv/versions/3.8.2/lib/python3.8/site-packages directory, so it doesn't look like pip telling me something that's not true. But it sure looks like python is.
I'm using pyenv on MacOS 10.14, not sure if that makes a difference. Anyone have ideas of what next steps should be?
ConfigParser is a built in library in Python, but its name was changed to configparser in Python 3. It appears like w3af is still using Python 2 (I found this check that actively states it, but you never even got that far). So, to run this code, you need to run it with Python 2.
There are very many (thousands) of python3 compatibility issues with the w3af codebase. The ConfigParser issue is just the first one you hit - the codebase is full of references to outdated / unmaintained libraries, and has no support for python3 byte strings vs. unicode strings (b"" vs ""), which are used throughout the codebase.
There is a w4af project on Github, where someone has made the effort to port all the w3af code to python3, but you didn't hear that from me.
I have apache ampps which comes with version 3.6.1 of python.
I was given various directions for installing pip.
None seemed to work.
For example,
link https://packaging.python.org/tutorials/installing-packages/
says that I can run:
python -m pip install -U pip setuptools
Get a whole bunch of errors. It might amount to: no module named queue.
Similar errors happen when I download the file they mentioned (get-pip.py) and run it from python.
Now, when I look at directions for installing queue, some point me to use pip. But when I try to install pip, it is complaining that queue is not there....
Hmmm...?
Now what?

import queue
ModuleNotFoundError: No module named 'queue'
From the format i see here.
Firstly, pip is an installer basically what you've confused yourself with is that pip = queue which is not the case. Pip is just a packager that helps you install packages. Queue is a different module
For your case here Queue is a part of multiprocessing module so you just put this at the top of your code:
from multiprocessing import Queue
and you do not need to add import pip into your code
hope that explained things better for you :)
This line:
python -m pip install -U pip setuptools
means use pip to upgrade the installations of pip and setuptools. Only works if you already have pip - which you probably do. It is a useful step to make sure your install environment is up to date, though.
pip does in places use queue. Note it's been renamed between python2 and python3 - if you have py3, which you claim, you have queue (it was Queue in py2). So I wonder if there's a version mismatch in something.
Windows installs always create problems. You might be safer installing and experimenting with a virtualenv so your experiments don't mess up the python install from the package you mention - ampps. There are plenty of notes on that elsewhere on stackoverflow... e.g. Python and Virtualenv on Windows
pip is already included in 3.6.1, but it is in subfolder Scripts.
it is not automatically a part of the path variable.
you have to change directory and run pip or you can change environment variable so that the location of pip becomes part of the path search.
I have installed Python 3.4 and wxPython Phoenix on Windows 10. I go into Eclipse and add wxPython to the external libs in my project, but when I try to import it, I get this error:
Traceback (most recent call last):
File "C:\Users\linus\workspace\MiCS 1.2\main.py", line 1, in <module>
import wx
File "C:\Python34\Lib\site-packages\wx\__init__.py", line 17, in <module>
from wx.core import *
File "C:\Python34\Lib\site-packages\wx\core.py", line 6, in <module>
from ._core import *
ImportError: DLL load failed: The specified module could not be found.
I did some searching and tinkering and still can't figure out what's causing it. It shouldn't be the msvcp or msvcr DLLs as I have Office running just fine (or is that an incorrect assumption?) Any help is appreciated. Thanks.
How did you install wxpython?
As of now, the top page of the official site has wxpython 3.0 only for python27. So, I suspect you might not have installed it properly.
If you have your python34 at C:/Python34 then, cd to C:/Python34/Scripts first so that we make sure to use the pip for this python.
According to this post (https://groups.google.com/forum/#!topic/wxpython-dev/LmGIrQyh7jc), try
pip install -U --pre -f http://wxpython.org/Phoenix/snapshot-builds/ wxPython_Phoenix
This should find the corresponding whl file for your python version and CPU architecture.
Or, you could manually download whl file at http://wxpython.org/Phoenix/snapshot-builds/
If you have 32 bit Python34, then look for ******-cp34-none-win32.whl
and simply do:
pip install path/to/the/whl/that/you/just/downloaded/wxPython_Phoenix-3.0.3.dev1839+4ecd949-cp34-none-win32.whl
After this, if you can import wx in the normal cmd then the problem should be coming from eclipse.
Recently, (I have no idea when), I installed this package called pymol. Today when I was trying to copy a list of all my install modules, I encountered this error.
~/Projects$ python -c "help('modules')"
Please wait a moment while I gather a list of all available modules...
Error: unable to initalize the pymol.cmd module
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/pymol/cmd.py", line 117, in <module>
from chempy import io
ImportError: cannot import name io
I've tried
sudo pip uninstall pymol
This definitely worked... but it also definitely did not work. It removed the .egg, and pip list tells me it's not installed, but the tool is still there. I open a python prompt and import it with no problem. Now my question is, if I just delete the package, is there anything that could go wrong, (WCS I'm thinking kafkaesque broken dependency fixing for the rest of my natural life.) and is there a standardized, best practice to remove this, or any other package manually.
I am trying to configure svn hook for email notification using mailer.py script from apache, but it always crash on import of svn libs. I try two ways of installing svn and python. I try to install everything manually using command line and use CollableNet installer that have preinstalled Python and all libs I need but result is the same.
Now I try to import one library from hole package that I need using python in command line and I have such response:
>>> import svn.core
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named svn.core
I try to fix it using:
1) import sys; sys.path.append("C:\csvn\lib\svn-python\svn")
and
2) C:\csvn\lib\svn-python\svn>python "\__init__.py" install
But it didn't help.
For now I have no package with setup.py to install it.
I spend a lot of time on this task, and going crazy a little). Please give me any suggestion how to fix it.
