Python doesn't install modules? - python

I can't seem to get a module installed with Python 2.7.3, or well, a lot of modules in fact. When I download the module, and then run "python setup.py install" from the folder, it looks like it installs - however, trying to import the module does not work. So, I went ahead and looked in site-packages - the only thing I found was the .egg file, which is not helpful in any way. Then, I did a search for the module in the entire folder of Python2.7, results: the .egg file and something totally unrelated. I have gotten some modules installed in the past (twill, BeautifulSoup, and a few others), some partially installed (pyglet, installed and in the folder, however running doesn't work) and then there's a whole load of modules that just don't install. They create a .egg file and that's it. Done. Nothing else. It's really annoying, so I'm wondering what could cause the issue?
The module I was trying to install was the feedparser module.
Edit: After doing >>>help() and then modules, it's not showing up there either.

You can use pip as a module (package) manager, better that installing things manually.

Plus using virtualenv is a good practice.

Installed module is not working (windows)

So long story short. I want to use requests and bs4 modules in my code. I installed them using pip install requests, pip install bs4. I double checked everything, even found installation folder and saw that the files is here, but my vs code is not detecting it and giving a error. I'm a quite new to this programming language so possibly it's a common issue. But i searched and mostly found posts about this problems on diffrent versions of linux, not windows.
Error i'm getting in vscode btw
Import "requests" could not be resolved from source
And when i'm launching the program through cmd the error is
ModuleNotFoundError: No module named 'requests'
First, you should add more information for us to know how your computer and IDE are configured. The first thing you should do is to check that VS Code is using the Python version where you have pip installed the modules. That is, clicking at the bottom-left space as in the picture below. Then checking that the modules are within that path.
Otherwise, check out virtualenv. With this tool you can create virtual environments within your project's folder and makes it easier to manage packages.

Python refuses to recognize library I am almost certain exists

I have no idea why this is so frustrating, but I have literally pulled out a few clumps of hair in rage because this just refuses to work and I honestly do not have the slighest clue on what to do. I am trying to use the winshell module for a quick python programming I am using. I am new to python and just started trying it today. I have tried to install the library manually, and through pip. pip claims the module is downloaded, and I can see it in the lib folder. No matter what I do I get this error when I try to run my code:
import winshell
ModuleNotFoundError: No module named 'winshell'
what on earth must I do to get this to work I am at my wits end here and I feel like I'm going to break something
You have to install the library with:
pip install winshell
I just tested with pip3 install winshell and it worked.
Python interpreter search for modules in the set of directories that you can see with:
import sys
print(sys.path)
I recommend you take a look to see if the directory where you are seeing the library in lib is include in that list.

Pip error when trying to install module

I'm trying to install PyDrive [a wrapper library of the google drive api for python] and pip is giving me this error. It did the same thing when trying to install things like matplotlib or mega.py [a mega.nz api for python].
Here's the error:
Anyone got a clue what's going on?
Cheers
You could try renaming that pip.py to something else.
There is a library called pip somewhere on your system (and it may also be bundled within pip.exe). That is different from the "entry point" script that actually runs pip from the command line. When you run pip, it will try to import the library called pip. If there is a script called pip.py in the Scripts directory (representing the entry-point script, not the library), it may import that instead of the real library. If this is indeed the problem, renaming pip.py to something else will remove the name conflict and allow pip to properly import the library it needs.
I'm not sure how you wound up with pip.py in your Scripts directory in the first place. I don't think it should be there. My Python installation on Windows doesn't have it.

How to make downloaded Python libs work on Windows?

I got this simple problem and I can't find the answer anywhere, I'm wasting a lot of time!
I did a Python programm on Linux (which works OK), but when I try to run it on Windows, there are too problems with libs...
I have installed the libs I need (dateutil, lxml, xmlrpclib...) in C:\Python34\Lib\site-packages. But then, they don't work as they do on Linux. For example:
from dateutil.tz import tzlocal
Gives me next error:
File "C:\Python34\lib\site-packages\dateutil\tz.py", line 9, in module
from six import string_types, PY3 ImportError: No module named 'six'
That is, they are not finding the other modules... why???
Have you try this ?

Maybe it can help
It looks like you're using Python 3.4 which comes with pip. pip is a tool for installing packages and any dependencies they might have (like the srting_types module from your error message). I'd suggest learning how to use it because it resolves most of the packaging problems with you needing to moving things around yourself. See an answer from a different question to learn more about pip.
There are some packages that need to be compiled. This can be difficult on Windows 7 if you don't have the proper toolchain set up to compile packages. I'd recommend Christoph Gohlke's wonderful collection of installable packages for Windows. You just need to make sure to grab the right version. Since 3.4 is still relatively new, some packages may not be available, so be warned.

Easy Install for Python and Eclipse Library Paths

Recently I found about this tool easy_install that help me to easy install additional python modules. The problem is that for each module it creates additional *.egg folder (sometime there is only an egg file?) (no source?) and I don't know how to setup eclipse paths.
By default I have included C:\Python26\Lib\site-packages and this is enough when I install python modules from source... but not when I'm using easy_intall
For example django instaled with easy_install is located in C:\Python26\Lib\site-packages\django-1.2.5-py2.6.egg\django and installed from source it's located in C:\Python26\Lib\site-packages\django
In fact when I'm using easy_install all installed modules are working without a problem, the only problem is that eclipse can't locate where is the source and gives me a false unresolved import errors
Where I'm wrong?
I'm assuming that eclipse does not search the egg files for source. Eggs, like jar files in Java, are just zipfiles of python code with some included metadata.
You'll also note that in site-packages you've got easy-install.pth and setuptools.pth files. Those files are parsed by python and used to add other directories and egg files to your PYTHONPATH (import sys; sys.path) so that Python can find the code in those locations. Eclipse isn't seeing those imports as valid because it is most likely not setup to take pth files into account.
To get Eclipse to recognize that Django is really installed you may want to try removing your easy_installed django package and reinstalling it with:
easy_install --always-unzip django
That way rather than installing a compressed egg file you'll have a normal package directory that eclipse should have a fairly easy time opening.
Alternatively, in your screenshot above it looks like you may just need to explicitly add each egg file you want eclipse to use.
