When I check the version of a package, I get a python version in parentheses. What does it mean?
This python 3.7.3 does not match with the PyCharm interpreter I am using (python 3.8). Is that the reason? Should I worry the version between parentheses is not the same as my python project interpreter?
It is possible that you have many python versions installed on your computer.
You probably need to pip install again the same package for the python version you are using with your Pycharm if you want them to work correctly.
if you are not sure how to do that with CMD commands,
you can access your Pycharm, look for "Python packages" at the bottom, and then search for your package.
You can see there is this package is installed already or not.
and if not - just hit the 'install' button.
after that, you are ready to go.

I'm shifting from pycharm to vscode for python development and want to check if most of functionality from pycharm such as debugging, gitlab integration, etc... Are possible in VScode.
I've learned that you could install python extension so I did install python v.2022.20.1 extension. However this debugging functionality does not work when I use python 3.6(it says in python extension that it supports python 3.7 and above). I want to find a version that support python 3.6, how can I find it?
I can click drop down beside uninstall block and install another version however there are lots of versions and it is cumbersome to click each one to check...
You can use 2022.08.* or previous versions, later versions no longer support python3.6.
I have a Raspberry Pi 3 with Raspbian and I upgraded python version from 3.7 to 3.8. If I type python --version in the terminal the correct version appears as the system version. However none of the modules that I have installed AFTER the version change seem to work. Python gives ModuleNotFoundError when trying to import ANY of the modules that I have installed.
I can see the modules with pip freeze but Python seems to not be able to find them.
I followed this instructions to purge 3.7. I reinstalled pip after purging python 3.7 but pip as again installed in /home/pi/.local/lib/python3.7/site-packages/pip. How can I get rid of 3.7 completely?
python3.8 -m pip install SomePackage # specifically Python 3.8 should work.
More documentation here: https://docs.python.org/3/installing/index.html#work-with-multiple-versions-of-python-installed-in-parallel
Just to summarize the comments and suggestions from other answers:
The problem I have was caused by the fact that even I had set Python 3.8 as default and python -v was pointing to Python 3.8 the pip script was installing modules for Python 3.7.
The suggested solution was to use pip3.8 (or whatever version someone might have) to install packages for that equivalent Python version and that works good.
Ideally best option if someone wants to have multiple versions of python is to use pyenv. You can create multiple virtual environments with multiple python versions.
However Do not uninstall the default Python. I have also tried to uninstall the default Python 3.7 to avoid having two versions of python 3 and keeping track of which module is installed where. This was a bad idea. I did not know that many Linux distributions have applications which use the default Python. You might get a black screen and who knows what other problems see this discussion Removed Python 3 on 18.04, how can I fix my system?
I have many different versions of Python, but a version that I use and that terminal show me if use command Python – version is 3.10.0.
When I use command pip list I got a big list of library, including the one I recently installed odfpy.
I open VsCode, choose Python version 3.10.0 and try to import odf but...
ModuleNotFoundError: No module named 'odf'
For sure I need to set something on VsCode or change some configuration in Linux but I cannot find a normal explanation of how to solve this issue.
If I change the Python version in VsCode with 3.8.10, odfpy (and also Django just installed) is recognized. So I suppose that, even if the Python version selected on the terminal is 3.10.0, when I pip install something, is installed on version 3.8.10. How do you manage this?
Please check which pip you are using through the command of pip --version.
After you switch the python interpreter in the VSCode, please create a new terminal, and make sure it has activated the environment you have selected.
I also use VS code and use Python 3.10 and i had try to download the odfpy which has gone alright, i use the command python -m pip install odfpy
try and see if it work for you though.
If it does not work, maybe try and create a virtual environment if you haven't created it yet.
In my case i was getting same error while using import-export django module. Installing odf library didn't worked got same error. I resolve this issue by simply pip install tablib==0.14.0.
I am using python 3.6.5 with PyCharm.
While trying to install any package, it gives the error
"Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'C:\projectPath\venv\Scripts\python.exe'"
Project path and actual python installed paths are different.
In settings of PyCharm, pip version is 19.0.3 and latest version is 19.3.1
Also, "python -m pip --version" from command prompt says pip version is 9.0.3
What do I do?
I imagine that you have more than one Python installed in your system.
you should go to Pycharm --> file> settings> project>project interpreter.
you should find the other Python instance on your system and try to change your interpreter to that one.
if it does not appear in the list click on the button that looks like star in front of the project interpreter.
I had the same problem.
I realized that I installed one python by myself and another is installed while installing PyCharm.
After changing my interpreter I do not receive that error anymore.
This error occurred to me too when using PyCharm, and trying to install MeCab in it. And by choosing mecab-python3 instead of just mecab (which is what is for Python2 I assume...).
You might install the package compatible to the Python version used in the package, but not to yours, which is that PyCharm refers to'dir:\projectPath\venv\Scripts\python.exe' . So you should choose the different version of the package, or change interpreter to another.
I got the same error along with no such option: --build-dir after upgrading pip from PyCharm's (2020.1 #PY-201.6668.115) terminal (PyCharm didn't allow me to do so from interpreter's settings).
Turned out older versions of PyCharm rely on --build-dir which was removed in newer versions of pip. To resolve the issue I had to downgrade pip.
Solution was found here
Faced same issue after trying to change the file path.
Tried changing the interpreter location but it dint work for me. so I uninstalled pycharm and re-installed it. working fine now.
I faced the same problem on Windows-10 (PyCharm 2020.1.2 version) when installing h5py package. I didn't want to change my interpreter as that will raise other compatibility errors in my code.
In my case:
What didn't work: upgrading the pip
What worked: I chose old h5py version-2.10 (instead of the latest h5py version selected by default by PyCharm) and it worked.
Mentioning just in case if this works for someone. Uninstalling both Python and Pycharm is too much to do for this error (in my opinion).
File-> settings
searching for project -> and choosing "python interpreter"
in "python interpreter" tab choosing "show all"
pressing in the left down side on "+" (add)
adding the right direction of python installed place and press "ok"
removing the previous version
I faced the same error while using Python 3.7.5 and Pycharm 2019.1.2 for my Django project.
It also causes failure in execution of many other python commands, and is not caused by environment variables or path.
I guess it's because some python files are broken or corrupted.
The easiest and fastest way I found to get out of this was :-
Uninstall Python.
Uninstall Pycharm.
And Reinstall latest versions of both.
I had the same problem and but see solution uninstall IDLE python and pycharm and install least version
Uninstall Python.
Uninstall Pycharm.
And Reinstall latest versions of both.
I'm trying to use different versions of python on win7, and I was told that I can use the python laucher.
I find the docs for it: https://docs.python.org/3/using/windows.html#launcher
But I don't know where is it. Someone say its called py.exe, but there is no file with this name on my computer.
I installed python 3.4.3 with Anaconda, https://store.continuum.io/cshop/anaconda/, comes with Scipy
===========
UPDATE:
Since there is no python launcer in Anacoda, how can I re-install it? Or if there is better way of using different version on Win7?
It should be in the root directory of Python 3.3 installs and higher. It is not available for Python2.
Go to C:\PythonXX\ and you should find py.exe for your version.
In Command Prompt or your favorite shell (like Cygwin), run:
py -3.3 -m path/to/myscript.py
However, this only works if you have a 3.3 or higher installed.
EDIT: Anaconda does not come with Python launcher. It is only available for an ActiveState, standard, or probably many other installs.
EDIT2: Here are two brand-new, Python 3.4 installs of ActiveState Python and Anaconda Python, screenshotted. Notice how Anaconda Python does not include py.exe and a lot of other (non-essential) executables?
EDIT3: After some "difficult" testing, just set anaconda as your default install for Python3.4 and grab the py.exe from another install. That is all. So you can install Python3.4 from another source, uninstall it, and save the py.exe, make sure it is in the system path, and the python launcher is fully installed.
EDIT4: Actually there's also a standalone installer available here:
https://bitbucket.org/vinay.sajip/pylauncher/downloads
If installing python from python.org's downloads and you select "[x] install pylauncher [x] install for all users", py.exe is installed in C:\Windows\py.exe.
I think if you don't install for all users, then it's in the python install root.
If you are able to run py from cmd.exe, then you can find out where it is with where py.exe.
It looks like the python executable is part of the conda command if you're using Anaconda, according to their website. According to Alexander Huszagh (see his answer), the python launcher doesn't come with Anaconda python.
Here is a blog post that is perhaps relevant.
I first tried everything Alexander Huszagh has written. But none of it helped.
It took me a really long time to find the Python Launcher. I had accidentally changed how to open .py-files. And once you change it, you can't do right mouse click "Edit with IDLE" anymore. I eventually found them in the C:\Windows\ directory named py.exe.
The experts gave a reply which seems relevant to one version of python but not the latest version. e.g. In my least favorite command line tool I entered:
C:\Program Files (x86)\Python36-32>dir py.exe /s
