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.
file > new project settings > project Interpreter > click in the drop down and select 'show all' > click the '+' button >
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.
PyCharm project interpreter problem Resolved
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.

I had Python version 2.7.17 already installed on my machine. Recently I started coding in Python and I installed VS Code to make things easier. However once I opened VSCode and ran a simple Python Hello World program, VSCode terminal gave a warning saying that
Python 2 support has ended at January 1, 2020
which means the support has already ended and suggested to install the latest Python version. So I heeded the warning and installed Python 3.8.5 on my Windows machine. The installation was completed without any issue. Afterward, when I tried the command python --version on VSCode terminal, it correctly gave the output python 2.7.17. However, when I tried the command python3 --version to check if it was correctly installed, the terminal gave no output.
Since I am a beginner and the support for Python 2 has already ended, I would like to work with Python3 from now on. However, I don't mind Python 2 staying in the machine.
Is this something should I worry about? Or should I uninstall Python 2 completely (When I checked Control Panel both versions are list under currently installed programs)?
According to your description, you can change pythonpath in vscode and still keep python2.
I assume you are using windows system and if not, please let me know. The following is the solution:
open cmd and type: where python. There should be two path, copy it which is about python3.8.5;
press Ctrl+, to open setting.json and add an entry for python.pythonPath manually inside your User Settings:
Now you can press Ctrl+Shift+P and find the option select interpreter. Click it you'll find a interpreter list. After selecting new interpreter, it is necessary to press Ctrl+Shift+` to open a new terminal for further development.
About more detailed information about pythonpath and interpreter you can refer to using python environments in vscode.
The version of Python used depends on your environment, and PATH variable.
I think you need to select the correct Python interpreter. At the bottom of your screen, there should be something that says the Python version number. If you click it, you can get a menu to select the interpreter.
Alternatively, you can hit control-shift-p, type "python interpreter", then click "select python interpreter" option.
Finally, you can alter the default Python interpreter used by changing the User settings in VS Code. Hit control-shift-p, type "open settings", and select Open Settings (JSON). Add a key to the JSON file called "python.pythonPath", so that you have a line that looks something like this:
"python.pythonPath": "full/path/to/the/python/executable/you/want/python.exe",
You might be able to get a hint as to the path to use or available isntallations of python if you type where python or which python (depending on terminal/ OS in use).
Then you can save those settings. Restart VS Code. Hopefully now the correct interpreter is selected by default.
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 downloaded Python 3.8.
I downloaded PyCharm Community Edition 2019.3.4. Saved it in new folder in the Desktop directory.
In PyCharm, when I click on File > New Project, I...
1.) Have the location set to C:\Users\User\Desktop\newProject
2.) Have New environment using set to Virtualenv
3.) Have Base interpreter set to C:\ProgramFiles\WindowsApps\PythonSoftwareFoundation.Python.3.8_3.8.752.0_x64_qbz5n2kfra8p0\python.exe
I have a Windows 10 Home computer
When I click on the Create button, I get the attached error.
What can I do?
The error says it has access problem while accessing python.exe. Files inside WindowsApps are for systems use and cannot be accessed manually by users due to access permission.
Also you installation does not seem right as python.exe is present inside WindowsApps.
Please follow the simple installation guide for python. You might run into many other problems later.
I would suggest reinstalling python. It should go directly into C:/ drive or C:/ProgramFiles.
This is the same question as this else but for Python.
The thing is that I've built my own installer package of Python interpreter (I've added modules and extras) and once installed I can't find the way to set the location of my custom Python installation dir in PyCharm IDE, I can't find any option to manually specify the location of python interpreter.
While I don't know if exist that option I'm thinking in other alternative, If maybe the PyCharm IDE takes the original Python path from a registry value then it should be sufficient for set the location, but I don't know if pycharm uses a config file or a reg key to get the python location and where is this value to modify it, I need help.
PS: I'm having the same problem for RubyMine IDE.
For PyCharm, in the IDE go to File -> Settings. In the Project Settings navigation panel, select Project Interpreter and then Python Interpreters, then in the right panel, click on the green plus (+) icon on the top right and select local. Navigate to the python executable you would like to specify as your interpreter.
You can also try this:
click on File
select Settings from the menu
in new Settings window click on Project and then Python interpreter
click on gear icon on the right, then on Add... option
in the Add python interpreter window select System interpreter from the list on the left
pick Python, click apply and you are done
I was having similar problems with PyCharm.
Having installed both Python 2.7 and 3.5 I was only able to find the the "python.exe" file for python 2.7.
I tried reinstalling Python 3.5 and attempting to change the installation path to C:// but it lead to several errors. This is the work around I found for getting 3.5 on PyCharm as an interpreter.
Copy the python 3.5 directory in windows explorer.
Paste it into PyCharms choose local interpreter area.
I have python installed with django. I know the installation is there because I installed it following the directions and in the command line I can do "import python" and there is no crash.
When I try creating a django project in pydev, I get an error: "Django not found."
What could the problem be?
I had the same problem and this is what I did just after installing eclipse:
Preferences > Interpreter Python
Pressed Auto-config
Selected /Library/Python/x.x/site-packages, which was not selected
(some django folders were in there, persumably the installation)
Clicked apply / OK
Creating a Django project afterwards should be ok.
Good Luck!
go in the menu to window -> preference -> pydev -> Interpreter - Python ; and add the python interpreter there, if you installed the django in a virtual environment you should add the python interpreter of the virtual env ; after adding the interpreter by clicking on new you should now click on Apply , you should see now all the system libs from PYTHONPATH added there between them Django .
hope this will help
Jaffa,
You might have configured your python interpreter in Eclipse prior to installing Django in python.
So what you have to do now is in Eclipse remove the Python interpreter and add it again (now that it has Django installed) and all should work ok.
I was having this same exact problem today, and I just wanted to add some notes to help people out. You can follow the instructions of antonkeren above, but there's one thing to note that was not mentioned. After adding the django directory to the path you must QUIT ECLIPSE OR APTANA STUDIO. After you restart it and try to create a django project it will work.
I stumbled upon this only yesterday myself: Django must not be among the system libraries for this to function...
I had the same problem and had solved it by adding the python home directory to the PATH variable and reconfigure the python interpreter on pydev.
Use auto config in the preferences option and then click apply and then ok.
If everything is done as said above, and still showing "Django not found" while your are trying to create django project, let try to double click 'django-admin' python file that in scripts folder of python. And try to create django project
I think I've got the same problem, Eclipse 3.5.2 on Fedora. In my PyDev Python interpreter settings I've got the site-packages/django folder (site-packages/django/bin too, just in case), but when I try to create a django project I get an error dialogue saying "It seems that the selected interpreter does not have Django available". Looks like I'm going to have to use Eric4, which is a pity because I can't get that working at all on my Windows rig!
Unless I manage to understand the cryptic advice above, "Django must not be among the system libraries for this to function..."
Same problem I have faced today. I took help from these answer.
but in my case it didnt work.
There is small modification in #antonkeren answer.
1) Go to Preferences. Windows > preferences.
2) Search for Pydev
3) Select Python Interpreter
4) Pressed Quick Auto-config
5) now download www.djangoproject.org/downloads django tar and extract on any location.
6) now click on Folder in "Libraries tab" of "System PYTHONPATH" and select your extracted django project folder location.
7) Click on apply and ok.
Creating a Django project afterwards should be ok.
Cheers...!!
