I have a project in pycharm which I am currently running in python 3.9
However, I want to compare how would it behave under python 3.11
I have tried File-Settings-Python Interpreter - Add Interpreter- Add Local Interpreter and tried adding 3.11 from there but it says "Environment location directory is not empty" and prevents me from doing this.
How can I make my project run under python 3.11?
You are doing it correctly. Make sure you have Python 3.11 installed (it runs outside PyCharm). You need to use PyCharm to pick the existing python command from your hard disk. Make sure you are adding an existing interpreter and use the... button to choose it from your disk.

I cloned a python environment and recreated it on a new machine using Anaconda Navigator with a yml file. My script runs fine in the new environment using PyCharm. The python version of this environment is 3.9.0. However the script doesn't run with IDLE because IDLE is running version 3.11.0.
IDLE is located at:
C:\ProgramData\Anaconda3\envs\CloneETL3\Lib\idlelib\idle.pat
The python interpreter which PyCharm uses is located at
C:\ProgramData\Anaconda3\envs\CloneETL3\python.exe
How can IDLE have a different version from the python interpreter when they were just installed fresh? How can I prevent multiple versions of python from running on my machine? I made sure to create a new project in PyCharm, use an existing interpreter using conda and point it to the exe I described above.
The environment was first created from a clone of my ArcGIS Pro environment.
Thanks for the help!
This is quite common in most editors. I use vscode which is similar to pycharm and the user can select the version of python (or other languages) that they wish to run.
It look like this:
The reason for this is that some users have the requirement of being compatible with previous versions. You should be able to select the latest version of each.
Alternatively you can delete all versions leaving only the one version that you desire, this would avoid confusion...
You could refer to this answer for that option: How to completely remove Python from a Windows machine?
When I start Pycharm, this python setup menu pops up.
Python 3.7.4 is not even the version I'm using. Everything else works fine and I can just close it, but it is annoying.
There was a same question, and the answer was
You appear to be using the installer .exe as if it were the Python interpreter. Install Python to somewhere first, then use the python.exe in the bin directory inside that.
But I can't find where my bin directory is. My Python37-32 folder looks this.
How do I find my python interpreter?
Open some project -> File -> Settings -> Project: ... -> Project Interpreter -> Show All ... to view the list of available interpreters added to PyCharm.
Find and remove the interpreter which is pointing to Python distributive from the newly opened list.
At some point in past you added Python installer as a project interpreter in PyCharm so now when IDE tries to use this exe to run some background tasks (e.g. to get sys.path) installation wizard is triggered instead.
Correct python.exe to point PyCharm to is right on your screenshot
According to official python documentation.
The Python interpreter is usually installed as
/usr/local/bin/python3.8 on those machines where it is available;
putting /usr/local/bin in your Unix shell’s search path makes it
possible to start it by typing the command:
Since you are using Windows here, you are already in the location where the python interpreter resides. So look no further.
By the looks of the screenshots, I have a concern whether you have installed python correctly.
If you did not select the checkbox for Add Python 3.7 to PATH, the wizard expects you to do it manually which is why the error.
I would uninstall and reinstall Python and this time make sure to check that box. I am sure your error messages should go away.
Alternatively, if you're not in the disposition to uninstall. According to python docs here you can set the python variable to PATH variable and try.
I'm new to programming and just started a course on Python. I want to use PyCharm, so I downloaded and intalled it (v. 4.5, community edition). I had previously installed Python 3.5 64-bit from python.org (I'm using Windows 10).
To start using PyCharm, I need a project interpreter, which I can select in the settings. As far as I'm concerned, the interpreter is "py.exe", but when I select it, I get this error message: "The selected file is not a valid home for Python SDK". I also tried to use every file whose name contained "python" or "py", and failed.
On every website and video I see, they select a file called "python.exe", but they're using Python 3.4 or a previous version. I checked that PyCharm supports 3.5 ("Initial support for Python 3.5").
Is there anything I'm doing wrong? What should I do to be able to use PyCharm?
All replies are appreciated. Thanks in advance.

Now, in the Virtualenv Environment tab under the New environment radio button, check the path in the 'Base interpreter:' field. For me, mine was set to an invalid path. Once I had corrected the path to point to python.exe I recreated my new project and PyCharm built the virtualenv.
For me there was a bit more too.... When creating the new project I expanded the drop down and had to verify the directory where the venv directory was being created. Once I had corrected the path here I had to click around a bit to get it to let me create the project.
I'm going to chaulk this up to a bug. I'm using Community edition.
When creating a project in PyCharm, if the interpret is not already selected, in the drop down menu under the projects "Location:", you can click the gear-looking icon to the right of the interpreter option, and click "Add Local"; then select the file location of the python.exe file that you have installed. It will probably be C:\Python35\Python.exe
I faced a Similar issue and was not able to find Python interpreter anywhere on the system.
The problem with it was that python was installed directly with default settings and there was no exe found in
C:\Python35\
and to solve this i tried uninstalling and reinstalling with custom settings and selecting allow for all users as well which did the trick and path was set correctly to
C:\Python35\python.exe.
After whichPycharm was able to detect the interpreter on this path.

I installed anaconda python distribution (Anaconda3-5.0.1-Windows-x86_64.exe) from the anaconda website. https://anaconda.org/anaconda/python
What it actually did was it re-installed my Python3.6.3 (pertinent to mention I have windows10, with pyCharm community & python 3.5 already but with the interpreter problem and while installing anaconda I chose the following settings and disabled my antivirus before my anaconda installation):
selecting allow for all users
installation path was set correctly and (stored safely for future)
restart my Computer after installation.(not essential-but I did)
opened Anaconda & Jet brian pycharm
selected new project in PyCharm screen shot of my New project default Python interpreter location = C:\Users\Skboy\PycharmProjects\dani Interpreter = C:\Users\Skboy\AppData\Local\Programs\Python\Python36-32\python.exe
Wow! my pyCharm started working for me,
Resolution : Python6.3 re-installation with proper custom setting
make a python test test1.py program file to print "hello python test world"
Run
now my Python Interpreter(automatically -by default select) Python 3.6.3
edit configuration & check for interpreter
(C:\Users\user1\AppData\Local\Programs\Python\Python36-32\python.exe)
Run
success test Run
worth to mention Anaconda Jupyter is a web based can also be used in case novice user are still having problems
I have had the exact same problem and was unable to find the solution until just now. Hopefully this works for anyone that was struggling with it.
I went to the location of the Python 3.5 (32-Bit) in my C: Drive which it turns out is just a shortcut to the actual Python application, right click on it and select Open file location which should direct you to the application version of python - simply called 'python'. This is the .exe file that PyCharm was looking for to use as the interpreter.
Now go to the configure interpreter menu in Pycharm and type in the file location of the actual python application. To get to mine I had to go to AppData/Local/Programs/Python/Python35-32. Click on the python.exe file and it should work.
This is my first post here so if its formatted incorrectly or doesn't use the conventional terms - sorry. Let me know if the solution worked for anyone else with the problem or if I fluked it.
If you kept the default settings while installing python, Your project interpreter for PyCharm will be:
C:\Users\yourUserName\AppData\Local\Programs\Python\Python36\python.exe
Chose the above location as your project interpreter inside PyCharm.
Depending on which python version you have, it could be either Python36\python.exe or Python35\python.exe.
For me the following solution it worked:
My configuration:
Pycharm Community edition 2019.1.1
Anaconda distribution with python 3.7. Interpreter in standard location.
Problem:
Pycharm was not able to find python interpreter after reinstallation of anaconda distribution.
Solution:
- Make sure you run pycharm as admin (right click and run as admin). This was actually the critical step.
- Create new project (or open an existing one)
- Depending on the choice choose interpter or go to file > settings > project interpreter > choose small gear on rights side > add > on base interpreter choose the 3 dots > paste the location of the interpreter in the anaconda distribution.
Hope it helped someone. For me the blocking point was that for some reason pycharm was not launching with admin rights.

Having installed Python 2.7 from here:
https://www.python.org/downloads/release/python-279/
I then uninstalled it using the control panel (I have Windows 7 pro). Now Python 2.7 no longer appears in the list of installed programs, however the files are still sitting in the same place on the C: drive.
I have since installed version 2.6 but I seem to be having some clashing issues between the versions. I'm having similar issues to this guy:
How to completely remove Python from a Windows machine?
I just want to know how can I remove Python 2.7 completely?
Will simply deleting the folders from my C: drive be sufficient?
How can I test that it has been completely removed?
You should just be able to delete the local files if you've already uninstalled from control panel. Also be sure to go to your environment variables and make sure that the python 2.7 directory isn't there. To do that,
Go to the start menu and right click on Computer
Click on Properties
Advanced system settings
Environment Variables and look for "path" under system variables
Be sure to erase C:\...\Python2.7.x
If you uninstalled from control panel it might not be there but it's probably good to double check. Also, be sure to delete the ; before C:\...\Python2.7.x
I had a similar problem. I kept installing Python 3.6 but when I typed "python" from the command prompt, Python 2.7 kept opening up despite the fact that I had uninstalled and it wasn't in my Path or in my Programs folder. I eventually solved the problem by uninstalling Enthought/Canopy from my computer and also erasing all the related files. Now I have a regular installation of Python 3.6 working and accessible from the command prompt. I assume I could now also get a parallel python 2.7 going, but I haven't tried to since I have no need for it at the moment.
The giveaway for me that my python 2.7 installation was strange was that when I typed:
python --version
into the command prompt, I was getting the following:
Python 2.7.6 -- CUSTOM
I have Python 2.7.8 installed and when doing the version check in my command line, it shows that I have Python 2.7.8.
However, when I run PyCharm it's running it on version 2.6. Is there a way for me to get it to make PyCharm take the 2.7.8 version?
Thanks for the help!
By default, PyCharm picks up the Python installed system-wide.
Which Python your project should use is configured under Project Interpreter section of your Project Settings. From there, you can add existing interpreters either locals, or remotes, even create brand-new virtual environments and manage packages inside.
