Sorry in advance if this question has been asked before,
So after some time, I wanted to start a new python project. My previous computer (on which my python files were) died. I had saved my projects in my Dropbox. Now I installed python (3.8, there is also an anaconda installation, but it should not interfere with the python installation) on my new PC, and I cannot import any library to those files.
The python shell can find the imported packages (imported using pip), but even when I move the files to C:\Users\Username\AppData\Local\Programs\Python\Python38-32\Scripts (single user installation). It doesn't work.
I have tried uninstalling and re-installing pygame (in this example. Any library is unusable) using pip, pip3 and even pip3.8, I have added the .whl file by hand, it all didn't work. I have tried a virtual environment, but I can't get that to work either.
I run Windows 10 on a 64-bit computer.
first be sure you know which python installation you use with which import files etc.
you can copy your files not in scripts, but in lib somewhere in site-packages dir.
add your scripts to the python path! sys.path.add(.....) Otherwise python is blind and can't see them

I'm very new to python and trying one of my first projects. I have installed modules 'pandas' and 'alpha_vantage' and imported them at the top of my code but they show the errors 'reportMissingModuleSource' for pandas and 'reportMissingImports' for alpha_vantage. I installed them in Command prompt and it was successful but it seems python doesn't recognise them or cant find them.
Potentially useful info:
When I first installed python I had to go into my Path settings and create a new Path to python.
I use VSCode
I had issues installing pip I cant remember why because I've been at this for hours.
Python version is 3.10.5 64bit
Pip version is 22.1.2
I am on Windows
I don't know what python files need to go where so they are slightly scattered around my directory.
Do I need to create a Path in my settings to each module, I already have one going to my scripts folder. I am very stuck so any help is appreciated.
Thank you for anyone that helps!
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.
I am new to programming and Python and what's really bothering me is that on my Mac, I'm used to knowing exactly where everything is and what's in every folder, but doing things through the command line is very different, so I don't know where things like Python Packages are being installed to by default.
According to the Pypi site, the packages are installed here: /usr/local/lib/python2.3/site-packages'
However when I cd to /usr/local/lib/, all I see in this folder are 'wx-python unicode', which I'm guessing was an accident on my part because I forgot to activate my virtual environment when I installed it?
Why is nothing in my /lib/ folder?
If you ever want to know where a module source file is located:
import some_module
print some_module.__file__
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.
I am in the process of migrating from an old Win2K machine to a new and much more powerful Vista 64 bit PC. Most of the migration has gone fairly smoothly - but I did find that I needed to reinstall ALL of my Python related tools.
I've downloaded the mechanize-0.1.11.tar.gz file and ran easy_install to install it. This produced C:\Python25\Lib\site-packages\mechanize-0.1.11-py2.5.egg.
I then ran a python script to test it, and it worked fine under the interpreter. But, when I ran py2exe to compile the script, I get a message that mechanize cannot be found.
I then moved the egg to a new folder, used easy_install to install it - and got every indication that it did install.
But, I still get the same message when trying to use py2exe - that mechanize does not exist!
I did a search for "mechanize" of the entire disk, and get only the 2 egg files as a result. What files should be produced by the install - and where should I expect them to be located?
Obviously, I'm missing something here...any suggestions?
Also, perhaps related, the python I am running is the 32 bit 2.5.4 version...which is what I had before and wanted to get everything working properly prior to installing the 64 bit version - plus, I don't see some of the tools (easy_install & py2exe) which seem to support the 64 bit versions. Is that part of the problem, do I need to install & run the 64-bit version - and will that be a problem for those who run 32-bit PC's when they run my scripts?
There is a note on the py2exe site that it does not work if the source is in egg format:
py2exe does not currently (as of
0.6.5) work out of the box if some of your program's dependencies are in
.egg form.
If your program does not itself use
setuptools facilities (eg,
pkg_resources), then all you need to
do is make sure the dependencies are
installed on your system in unzipped
form, rather than in a zipped .egg.
One way to achieve this is to use the
--always-unzip option to easy_install.
Which version are you running? The latest version listed at pypi.python.org is version 0.6.9 but there is no indication I can find if the problem with eggs is fixed in this release.
As other users suggested as above... I hereby summarize the steps I need to make Mechanize and BeautifulSoup work with py2exe.
Converting .py Files to Windows .exe
Follow instructions in here: py2exe Tutorial
STEP 1
Download py2exe from here… http://sourceforge.net/projects/py2exe/files/
(I am using Python 2.7)
I installed 0.6.9 for Python 2.7
py2exe-0.6.9.win32-py2.7.exe (201KB)
Install it
STEP 2
Try a hello world file.. to make sure all works.. as given in
http://www.py2exe.org/index.cgi/Tutorial
Python setup.py install (step 2 on web tutorial)
Then use a setup.py (step 3 on web tutorial).
See Issues below for any problems with Modules (under this folder: C:\Python27\Lib\site-packages)
STEP 3
Test the executable file.. in the dist directory.
In summary, when you have problems with modules, make sure you visit the site packages directory.. and see if the full package is there instead of just the .egg file.
py2exe cannot make use of just the .egg file (a layman's understanding).
Issues:
Mechanize module was not found by py2exe.. this was due to my first installation of mechanize on my local machine was just an .egg file (mechanize-0.2.5-py2.7.egg.OLD 324KB).. I need to install the full mechanize like this:
easy_install --always-unzip <library_name>
I did that.. then this time mechanize was installed in a folder named mechanize-0.2.5-py2.7.egg (1.1MB).
Also beautifulsoup-3.2.0-py2.7.egg originally the .egg file was 69KB… and after installing with
easy_install -–always-unzip BeautifulSoup
it was installed in a folder named beautifulsoup-3.2.0-py2.7.egg (229KB).
