I'm attempting to use click within a Python 3 virtualenv (3.9.5) script and I keep getting an import error even after installing it via pip. When I attempt to install it again it says requirement already satisfied. I feel like I'm missing something simple.
Although you are using virutalenv but just in case, make sure you are using the same version of python where click is installed, to run your script.
try to do a pip freeze or pip list to check all the modules installed, do it with and without the virtualenv activated. sometimes a simple restart of the cmd prompt can solve the issue. These kinds of problems are common in windows
Not sure but I think you should try again by changing name of virtual envirment. Because you have used same name for virtual envirment.

I keep trying to install pip in various different ways, yet everytime I try to, it does not work. I tried to investigate by going to the Python folder in C:\Users(my pc name)\AppData\Local\Programs\Python, and even after I deleted my previous Python folders, uninstalled and fixed my PATH variables. Any clue why this is happening?
Update: No solution has been found, so for now I'm going to hard-reset python by uninstalling everything, then trying to reinstall and such. I'll make a second update if what I try works.
Update 2: Got the same error, so reverted back to 3.10.9, and it was completely fixed. Not sure why 3.11.1 doesn't work with my pc, but I fixed it by updating my pip.ini file in %APPDATA%\pip\pip.ini .
Because in your case older python was installed before latest. Overlap happend in namespase, when new python took python name, but new pip dont.
That issue occurs because pip is actually separate from python. And it have new lead number versions often, which probably occured in betwin your python versions installations.
Deleting all Python versions and clean install, starting from latest version, seems easiest solution.
If you have more than one python interpreter, things may become messy.
The best way to do that is by using virtual environments.You can use native python venv, Poetry or even Conda.
Or you could call pip module using the desired interpreter:
c:\...path_to_python_3_11\python.exe -m pip install my_module
I am trying to check what packages are installed in my virtual environments, I have different packages from different virtual environments depends on what project I am working on. Whatever virtual environment I switch I always get this error when using help("modules")
aiohttp dependency is not installed: No module named 'aiohttp'. Please re-install black with the '[d]' extra install to obtain aiohttp_cors: `pip install black[d]`
My question is how do I install this package correctly, and by that I mean should I install it in my main Python PATH? I'm not sure if this is a mandatory package that I need it installed in my main environment if that makes sense.
My Python version is 3.9.6 by the way.
EDIT: I was able to fetch all of my packages.
I had to do a . Scripts/activate first, but it was weird because before I did not have to do the activate command before, since VS Code displays on the lower left portion of the screen what environment you are currently using, I'm not sure if I had any settings change prior to this bug.
Maybe you should try to open new terminal
thanks for reading this. I am using macOS High Sierra. I am not very familiar with terminal or environment variables, but am trying to learn more. From reading other threads and google, it seems like I either have multiple pythons installed, or have pythons running from different paths. However I am not able to find a solution to resolving this, either by re-pathing my IDLE or deleting it entirely.
I do have python, python launcher, and anaconda (not very sure how anaconda works, have it installed a few years back and didn't touch it) installed. I am trying to install pandas (pip install pandas), which tells me that I have it installed, but when I run it on IDLE, it says module not found. Though if i run python3 on terminal and type my code in, it works (so pandas has indeed been installed).
When i run which python on terminal, it returns
/Users/myname/anaconda3/bin/python
(when i enter into this directory from terminal, it shows that in the bin folder, I have python, python.app, python3, python3-config, python3.7, python3.7-config, python3.7m, python3.7m-config)
When i run which idle on terminal, it returns
/usr/bin/idle (im not even sure how to find this directory from the terminal)
When i run import os; print(os.path) on IDLE, it returns module 'posixpath' from '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/posixpath.py'
Would really appreciate some help to figure out how to ensure that when i install modules from terminal, it would be installed into the same python as the one IDLE is using. Also, I would like to know whether it is possible for me to work on VSCode instead of IDLE. I cant seem to find suitable extensions for data science and its related modules (like statsmodels, pandas etc). Thanks a lot!
First of all, a quick description of anaconda:
Anaconda is meant to help you manage multiple python "environments", each one potentially having its own python version and installed packages (with their own respective versions). This is really useful in cases where you would like multiple python versions for different tasks or when there is some conflict in versions of packages, required by other ones. By default, anaconda creates a "base" environment with a specific python version, IDLE and pip. Also, anaconda provides an improved way (with respect to pip) of installing and managing packages via the command conda install <package-name>.
For the rest, I will be using the word "vanilla" to refer to the python/installation that you manually set up, independent of anaconda.
Explanation of the problem:
Now, the problem arises since you also installed python independently. The details of the problem depend on how exactly you set up both python and anaconda, so I cannot tell you exactly what went wrong. Also, I am not an OSX user, so I have no idea how python is installed and what it downloads/sets alongside.
By your description however, it seems that the "vanilla" python installation did not overwrite neither your anaconda python nor anaconda's pip, but it did install IDLE and set it up to use this new python.
So right now, when you are downloading something via pip, only the python from anaconda is able to see that and not IDLE's python.
Possible solutions:
1. Quick fix:
Just run IDLE via /Users/myname/anaconda3/bin/idle3 every time. This one uses anaconda's python and should be able to see all packages installed via conda install of pip install (*). I get this is tiresome, but you don't have to delete anything. You can also set an "alias" in your ~/.bashrc file to make the command idle specifically linking you there. Let me know with a comment if you would like me to explain how to do that, as this answer will get too long and redundant.
2. Remove conda altogether (not recommended)
You can search google on how to uninstall anaconda along with everything that it has installed. What I do not know at this point is whether your "vanilla" python will become the default, whether you will need to also manually install pip again and whether there is the need to reinstall python in order for everything to work properly.
3. Remove your python "vanilla" installation and only use anaconda
Again, I do not know how python installation works in OSX, but it should be reasonably straightforward to uninstall it. The problem now is that probably you will not have a launcher for IDLE (since I am guessing anaconda doesn't provide one on OSX) but you will be able to use it via the terminal as described in 1..
4. Last resort:
If everything fails, simply uninstall both your vanilla python (which I presume will also uninstall IDLE) and anaconda which will uninstall its own python, pip and idle versions. The relevant documentation should not be difficult to follow. Then, reinstall whichever you want anew.
Finally:
When you solve your problems, any IDE you choose, being VScode (I haven't use that either), pycharm or something else, will probably be able to integrate with your installed python. There is no need to install a new python "bundle" with every IDE.
(*): Since you said that after typing pip install pandas your anaconda's python can import pandas while IDLE cannot, I am implying in my answer that pip is also the one that comes with anaconda. You can make sure this is the case by typing which pip which should point to an anaconda directory, probably /Users/myname/anaconda3/bin/pip
First: This would be a comment if I had enough reputation.
Second: I would just delete python. Everything. And reinstall it.
To repeat and summarized what has been said on various other question answers:
1a. 3rd party packages are installed for a particular python(3).exe binary.
1b. To install multiple packages to multiple binaries, see the option from python -m pip -h.
To find out which python binary is running, execute import sys; print(sys.executable).
3a. For 3rd party package xyz usually installed in some_python/Lib/site-packages, IDLE itself has nothing to do with whether import xyz works. It only matters whether xyz is installed for 'somepython' (see 1a).
3b. To run IDLE with 'somepython', run somepython -m idlelib in a terminal or console.
somepython can be a name recognized by the OS or a path to a python executable.
I did a pip install chatterbot.
and I imported the same in a python program which while running showed a
module not found error.
Can you confirm that the pip install initially worked without any errors? If there was an issue there, it is likely due to the module name that you're using.
If that's not the case, do you know which version of python you're using? The problem may be that you're using python 3. In which case try pip3 install chatterbot instead.
First, check if this module really exists in system using pip freeze. If it shows your module installed, then check for correctness in import string, and make sure that your pip points to the interpreter you're using. If you're using venv, it must also be taken account for.
Second, take note that the chatterbot.ChatBot needs to be imported like
from chatterbot import ChatBot, not just import ChatBot.
Best of luck!
Do you use Windows or Linux?
If you use Windows. Did you set the enviroment variables?
I followed the instructions in this post. Everything installed successfully. However, when I run python I cannot import pygtk. Specifically, it says this:
>>> import pygtk \n
“ImportError: No module named pygtk”
I'm guessing I have to do some commands like make or something, but I can't find anywhere where it says what to do. Please help, I am getting very frustrated.
Edit: I should probably mention I'm on Mac OS X
How are you running python? Is it the one that comes with OSX (/usr/bin/python) or the MacPorts version (/opt/local/bin/python)?
The page you linked to has the instructions for installing pygtk under using MacPorts. So it should run with that installation of python. See the MacPorts wiki for help on how to configure your PATH variable to use the appropriate python installation.
EDIT: Try running the macports python explicitly: "/opt/local/bin/python" and then import pygtk. Also, check under the macports python site-packages directory on the filesystem to see if pygtk exists there (usually something like /opt/local/lib/python2.5/site-packages).
If you are running git mergetool from virtual environment, then python interpreter cannot find pygtk. fix your python path for virtualenv or deactivate virtualenv first.
Below worked for me - assumes you have HomeBrew installed
I was trying to install meld and was getting the same error - this fixed it
brew install python
It is likely that you've installed pip separately (rather than through macports). So, your packages are being installed in a location that is not readable by macports-installed python. For example, in my OS X, the following code works:
[user]$ /usr/bin/python
>>> import pip
>>> for package in pip.get_installed_distributions():
>>> print package, package.location
But if I start /opt/local/bin/python (which is my default python) and say "import pip", then it gives an importerror stating there is no module named pip.
There might be two things that work for you:
1) Install pip using macports, and set that as your default (port install pip). Install pygtk again with this pip
2) Launch python explicitly with /usr/bin/python, and write your codes there.
There may be a way to have the /opt python (from macports) read modules installed by non-macports pip, but I am not aware of it.
a> pip install pygtk - (windows only),
b> brew install python
Not sure why, first options is saying its only works on windows.
Below is working fine for me.
A very general view on the problem, this is what I do if python complains about not finding a module that I know exists:
(This is very general rather basic stuff, so apologies if this is stuff that you already tried even before posting here... in that case I hope it'll be useful to someone else)
1: Go to the python installation directory and make sure the module is actually there (or: figure out where exactly it is -- I have some modules that are part of a project, and thus not in the main directory). ... sometimes this will uncover that the module is not actually installed although it looked like it was)
2: make sure you're writing it correct (capital/lowercase letters are a likely source of frustration -- the import statement needs to reflect the module's directory name)
3: if it isn't located in the python path, either setting the $PYTHONPATH environment variable or putting something like this at the beginning of your script will help:
import sys
sys.path.append('\\path\\to_the_directory\\containing_themodule')
(double slashes required to make sure they're not read as special characters)
in this example, pytk would be in \path\to_the_directory\containing_themodule\pytk'.
