I am trying this program ( https://gist.github.com/eknowles/9939273) to work but when I put the code in PyCharm, it underlines json, requests and BeautifulSoup imports and it says "no module named beautifulsoup...".
Then I tried to install with "easy_install requests" or "easy_install json" but it spits this:
PS C:\Users\Ruzgar> easy_install json
Searching for json
Reading https://pypi.python.org/simple/json/
Couldn't find index page for 'json' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/
No local packages or download links found for json
error: Could not find suitable distribution for Requirement.parse('json')
How can I make this code work?
I understand that I have to fix this import problem first. (I use Python 2.5.4 by the way)
Python 2.5.4 I am using.
You need to update your version of Python. Requests and BeautifulSoup require Python version greater than 2.6; and json is also included in Python from version 2.6
I recommend you install the latest stable version of Python 2.7. You can find it at the download page.
I cheanged the project interpreter to Python 3.4. Now it gives me
different modules are not installed.
Use Python 2.7 as not everything is compatible with 3.4. Once you have downloaded and installed it, restart PyCharm and load your project again; then follow the following steps:
Click on File, then Settings
On the left, under 'Project Settings', click on Python Interpreter
On the right hand side, click on 'Configure Interpreters'
On the right, you will see a list of interpreters available on your system. The interpreter for your project will be highlighted. In the bottom half you will see the packages installed for the interpreter. Click on "Install".
You'll see a new window popup. This is a browser for the Python Package Index (PyPI). In the search box, type requests; when you see the results filtered, click on requests, and then click Install Package. Repeat this process for BeautifulSoup. Remember, you don't need to install json since its already included.
Click Apply, then OK to dismiss the window. Give PyCharm a few seconds to rebuild its cache, and everything should work.
download the package of beautiful soup （I think you should download
the Beautiful Soup 3 because your python version < 2.6）and install it;
if you want to know more about this package,see here

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 trying to reinstall Python, so I go control panel > uninstall > Python 3.6.2. It succeeds, but when I try to download 3.6.*, it says that I can't download because there is already a version of Python3 installed.
I tried to clean the registry, deleted all files named "Python", but still see the error. I even deleted the path Python in PATH.
This may be a silly solution, but for me the issue was the Python Launcher still listed in the apps list after the uninstall. Uninstalled it separately, afterwards reinstalled Python without the error.
The installer/uninstaller does not do a good job of cleaning up after itself (and that's being generous). What worked for me:
Remove all python binary folders from Program Files and Users\<username>\AppData
Clean the PATH of any and all mentions of python
Search the registry in Computer\HKEY_CLASSES_ROOT\Installer\Features for any values with python, then delete the containing key. The key names are things like "03CEBFB8CC334B3148F9B330F67264A6" (that's an example, not an actual one, since the actuals I deleted)
#3 is the one that actually got it past the hurdle, but #1 and #2 should be done anyway.
My issue persisted despite all the above. If you're still having issues:
I realized the Python installer shows a log file link... wish I had noticed it sooner. Click to open that log, search for "Detected". Find all lines with "Detected related package". These lines are specifically what's tripping the installer. Notice the version numbers are higher than the version you're installing, along with the "Operation: Downgrade"s).
Once you find these GUIDs in your log, you'll need to search each of them in the registry. I use a free registry tool called Resplendence Registry Registrar Manager (I have no connection with them), which searches the registry blazingly fast and will show everywhere it finds something. But you can also just use Windows' native RegEdit, as well.
When you find one of these GUIDs in the registry, rename the key by adding an underscore to it, like below. This is the equivalent of "deleting" them -- as far as the Python installer can tell -- but without actually deleting them. You can easily revert them if needed.
Re-run the Python installer and it should now install just fine.
Delete all the files of the old version python and try to re-install to uninstall the older version you can do it from control panel
Install another version. For example, if you are installing a 64-bit installation, then try to install 32-bit.
Download zip file from below URL.
https://www.python.org/ftp/python/3.6.0/python-3.6.0-embed-amd64.zip
Copy all the contents to the python folder which is registered in the environment.
I managed to fix all this Python cringe by doing this:
Download newest version of Python for your version after the first point. In this case it's Python 3.6, so I downloaded the latest available - 3.6.8:
https://www.python.org/downloads/release/python-368/
Run it.
Check the checkbox "Add Python to Path":
Press on the Custom Installation button:
Press Next:
Install:
It should install. Now go to Control Panel\Programs\Programs and Features, press RMB and uninstall:
Now run your wanted Python 3.6.X installation again.
If it still gives you the "A newer version of the Python launcher is already installed", run the latest installer again as in all the previous steps, but instead, check the "Install for All Users" checkbox:
Then uninstall this latest version again.
And then install your wanted Python 3.6.X installation again.
I'm throwing hands in the air, personally
I had to do it just now for 3.6, 3.7, 3.8, 3.9 and 3.10 versions because I had problems with uninstalling and installing with errors "no python installation was detected" and "A newer version of the Python launcher is already installed". Why do I have all these different versions of Python? Because different programs want different versions of Python installed and refuse to work with any other(lmao).
World would be a better place without Python.
For me, the solution to the problem (a newer version of the python launcher is already installed) was to install it via the web installer from the website (https://www.python.org/downloads/windows/)
Download the Windows x86-64 web installer. The installer took for his series (3.7). Oddly enough, it worked the first time. Previously, the registry was cleaned, and the removal of possible traces of the program - all to no avail.
I'm a complete beginner in Python programming. I have trouble installing/importing the module 'requests' on python. When I use my command terminal to install requests, I get a message that requests is already installed. However, when I try to import requests into the file I'm working on, python tells me there is no such module installed.
Sorry to bother you with this silly and probably easy question, thanks in advance!
If you use PyCharm (which is a great choice in my opinion), go to the tab Run and select Edit Configuration and in the window that just opened make sure the your Python interpreter is the one you used when you pip installed the package you asked about.
You can check your Python version or just see in PyCharm if the requests is actually installed by going to the tab File, select Settings, click on Project: name_of_your_project and finally check in Project Interpreter that the package is installed.
I'm using netbeans to write a simple python program which I need the requests module for, I've downloaded requests through terminal and it all seems to be fine there but netbeans can't seem to find it.
This is the error that it's throwing up:
import requests
ImportError: No module named requests
I've tried installing the requests library directly into the python folder but the folder won't let me paste anything into it.
There do seem to be answers on the netbeans forums but their server is down so won't let me on their website to my annoyance!
EDIT
I've tried to run python setup.py install as per other answers on the website but had no luck.
EDIT
have tried completely uninstalling python and requests to make sure it wasn't an installation error but still no luck.
This clearly looks like an error of installation of the request module to some other place than where your netbeans expects when running the code.
In your console run
which python
Check if this gives the same path as the one set in your netbeans. You can set your path by adding new platform using Tools > Python Platforms > New:
I would suggest that you learn bit more about sandboxed environments such as virtualenv. This article shows how you can use a virtualenv to install packages and use the same virtualenv for netbeans so that whatever packages you install in the virtualenv will be available in the netbeans for you to use. For this case, it could be requests.
In the end I gave up with requests, as I was using requests to get json data from an API I decided just to go back to the drawing board and start over rather than attempt to fix something that I couldn't work out. I am now using the urllib import and whilst this may not be the most efficient way it works which is the most important thing.
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).
