I was postponing this question since i am not sure this is the right place to ask it. But i don't find a clear answer either.
I am running pycharm 2018.1.4, on windows and it seems that i can't change the virtual env that running in the terminal in pycharm. When i check the python version in the terminal i get version 2.7.3, for the project interpreter i have python 3.6 and for my run configurations i have the same 3.6 interpreter. There are no problems running the development server or anything like that, just in the terminal i can't run the manage.py script without getting following.
ImportError: Couldn't import Django. Are you sure it's installed and
available on your PYTHONPATH environment variable? Did you forget to
activate a virtual environment?
I understand the error, i just dont get why it is using that virtuals env instead of the one configured as project interpreter. Anyone else stumbled upon this problem?
As far as i know, Pycharm's terminal is not bound to Project Interpreter and the IDE related features.
To make it work, you'll have to manually activate your virtualenv in the terminal.
It can be due to various reasons,
You can try the following command once the virtualenv is activated
python --version
If it shows python 2.7 as the version then it means in your system you have given python command to respond to the 2.7 version. Its more like a name tag.
Try python3 --version and it should give you back "Python 3.6".
If that's the case, then use python3 manage.py runserver and it should work perfectly
In Pycharm go to project setting,then go to project interpreter make sure that you have your required python virtual environment (which I think you did it already)
Under same selected environment, make sure that you have installed Django
Of course, if there is the dependency on Django, you can just type
pip install django

I'm using Pop_OS! Linux. Whenever I make a Python Virtual Environment using mkvirtualenv and then pip install packages into it, that environment does not work when I reference it inside pycharm. I set up virtual environments using virtualenv and virtualenvwrapper.
The workaround I've found is to build any virtual environment you need to use inside of PyCharm inside of pycharm, or using the terminal inside of PyCharm. I'm annoyed it doesn't seem compatible with my native terminal, and can't figure out why. I even get slightly different python versions by running python --version both inside the PyCharm terminal and in the native linux terminal, while inside the same virtual environment! It's like Pycharm isn't reading the same information out of the python environment directory as my terminal is.
What is going on here, and how do I harmonize PyCharm with the rest of my linux machine? I'm also new to Pop_OS! Trying it out for the first time is an adventure.
IDK if that will work, but maybe if you install your packages via the "Python packages" tab in PyCharm (down left -> add package next to the research bar that appeared), PyCharm will see them while it installed them itself.
Bottom Line:
I can get everything to work by configuring two separate virtual environments, one for pyCharm and one for the CLI. Is this really necessary or should I be able to use 1 virtual environment for both as I expected?
More Detailed explanation:
I'm very new so this is probably a facepalm type of question so i'll try to be terse.
I'm using Linux Mint, Python 3.6, django 3.0.3, and pyCharm 2019.3.1.
I can create a virtual env using venv in the cli and it works.
I can also create a NEW virtual env in pyCharm through the settings: Project: Interpreter interface, and it works, however it doesn't have venv as an option, it only has virtualenv.
But if I try to activate the virtual env i created in pyCharm from the cli (using virtualenv of course, not venv), it fails hard and thinks i'm using python 2.7 which isn't even installed on my system. If it try to point pyCharm at the virtual env I setup on the cli, I get an error 134.
Is this just a known/expected issue? Must I have two virtual environments for every project I want to access via both pyCharm AND the cli? And I assume this is unrelated but I also find it odd that pyCharm lists my interpreter as python 3.7, which also is not installed on my system. I'm using 3.6 alone.
Thanks for your time.
At this time, I'm going to just answer this as: you need a separate virtual env for each (pyCharm and CLI) as this approach is not difficult or time-consuming and I have not had any issues working in this way.
I was required to install anaconda for a CS course and used spyder and Rstudio.
Then, for a different class I used pycharm.
When I type on the command line "python -V" I get:
Python 3.6.1 :: Anaconda 4.4.0 (x86_64)
and I have no idea why it relates the python version I have installed with Anaconda (and why not pycharm?). I understand that the OS runs python 2.7 (shouldn't I get that instead? and when I type python3 -V get which version of python 3 I have?) and when I use something like Pycharm or Spyder I can choose which version I want from the ones I have installed and use it within the program, not for the terminal.
I just want to have everything in order and under control. I don't think I understand what Anaconda really is (to me is like a program that has more programs in it...). How do I keep anaconda to itself ? 1313
Also, should the packages I installed through Terminal work on both pycharm and spyder/anaconda even though when I used pycharm I used python 3.5 and anaconda 3.6?
I think I need definitions and help to get everything in order in my head and the computer.
Pycharm is just an application to help you write code. Pycharm itself does not run python code. This is why in PyCharm, you need to set the interpreter for a project, which could be any python binary. In PyCharm, go to Preferences > Project > Project Interpreter to see where you would set the python environment being used for a given project. This could point to any python installation on your machine, whether that is the python 2.7 located at /usr/bin/python or a virtual environment in your project dir.
The industry standard way to "keep things in order" is to use what are called virtual environments. See here: https://docs.python.org/3/library/venv.html. A virtual environment is literally just a copy of a python environment (binaries and everything) so whatever directory you specify. This allows you to configure your environment to however you need in your project without interfering with other projects you might have. For example, say project A requires django 1.9.2 but project b requires 1.5.3. By having a virtual environment for each project, dependencies won't conflict.
Since you have python3.6, I would recommend going to you project directory in a terminal window. Running python -m venv .venv to create a hidden directory which contains a local python environment of whatever your 3.6 python installation. You could then set your project interpret to use that environment. to connect to it on the command line, run source .venv/bin/activate from where you created your virtual environment. run which python again and see that python is now referencing your virtual environment :)
If you are using a mac (which I believe you are from what you said about python2.7), what likely happened is that your anaconda installer put the Python bin directory on your PATH environment variable. Type in which python to see what the python alias is referencing. You can undo this if you want by editing your ~/.bash_profile file if you really want.
You are more or less correct about anaconda. It is itself another distribution of python and contains a load of common libraries/dependencies that tend to make life easier. For a lot of data analysis, you likely won't even need to install another dependency with pip after downloading anaconda.
I suspect this won't be all too helpful at first as it is a lot to learn, but hopefully this points you in the right direction.
I'm trying to work with python in PyCharm, and set up a virtualenv for my project. What I imagine should be the way this works is that I set up a project to pull from a repository. It's a Django project, so I enable Django support. Setting up a pyenv is good hygiene, so I set the interpreter to use a pyenv. PyCharm supposedly includes pyenv, so I don't need to install it from my os, and I was under the impression that either Django came with it as well, or I could install it from PyCharm.
Instead of any of that working the way it seems like it should and has been described, pyenv doesn't appear to be installed:
$ pyenv
No command 'pyenv' found, did you mean:
Command 'p7env' from package 'libnss3-tools' (main)
Command 'pyvenv' from package 'python3-venv' (universe)
pyenv: command not found
$ virtualenv
The program 'virtualenv' is currently not installed. You can install it by typing:
sudo apt-get install virtualenv
Of course, the only reason I'm even caring about that is that going to Settings --> Project --> Project Interpreter to install new modules doesn't work, either with or without a Pycharm-created virtualenv. I made a post to the Jetbrains forums here, but I'm not expecting a response, as they seem almost completely abandoned.
Then I thought I'd try enabling Django support, so that I could at least get that module working. But instead it says that Django isn't installed; In the Run/Debug configuration, at the bottom it says Django is not importable, the django icon has an x on it, and of course, every import django statement is underlined in red, indicating it can't be imported. My versions are:
Ubuntu 15.10
PyCharm 5.0.4
Python 2.7.10
So why does everything seem to be broken? What am I missing? If I have to install outside of pycharm, I don't really care, I'm just trying to set everything up the right way, so that nothing steps on anything else, and everything works as intended. Pycharm seemed to "volunteer" to handle everything, and I'm just trying to make that work. Using a pyenv seems to be what everyone recommends, and I'm just trying to do that. Any help at all would be appreciated.
To install Django on your virtualenv using pyenv please use the following command line:
pyenv activate <virtualenv_name>
pip install django
Or (for example if pyenv fails to activate your virtualenv due to some reason) it is possible to just execute pip using the full path:
<path_to_virtualenv_folder>/bin/pip install django
Then select the Python interpreter from your virtualenv as a project interpreter in PyCharm.
Normally PyCharm should be able to install packages, if it doesn't work please submit an issue to PyCharm tracker.
When I switch my PyCharm to use Python 3.4.3 and I am getting the error:
Invalid Python SDK
Also PyCharm does not automatically find the Python 3.4 interpreter for me, even though it is on the desired path /Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4. See the screenshot:
Despite this the interpreter does work. I am able to get correct output as expected, but code completion related to Python 3.4 is not working.
E.g. print("hello world!) still shows an error on the editor, but the console shows the correct output.
This also happened to me. I renamed a repository and then my virtual environment got stuck in the old path.
I grepped all configuration files and could not find any reference to the old one.
What finally solved the problem was to clear caches with the option File > Invalidate Caches / Restart...:
I had the same issue.
Try to comment/remove the PYTHONPATH variable in your ~/.bash_profile
#export PYTHONPATH=/usr/local/lib/python2.7/site-packages/
If it does not help it also may be useful to look in the idea.log for the errors:
/Users/username/Library/Logs/PyCharm40/idea.log
I had the following errors:
Your PYTHONPATH points to a site-packages dir for Python 2.x but you are running Python 3.x!
PYTHONPATH is currently: "/usr/local/lib/python2.7/site-packages/"
You should `unset PYTHONPATH` to fix this.
I go the same error message in Windows version of PyCharm after I re-installed Python (3.5) on a different location. The problem was that most of my existing virtual environments registered in PyCharm were still referencing the old installation of Python.
I resolved it by deleting these existing virtual environments and creating a new one. If deleting existing interpreters (in virtual environment) is not an option, you should be able to modify them instead in File | Settings | Project Interpreter
I got the same issue, when I updated Python (3.x) version via Home brew in MacOS.
Above answers didn't work for me. But with those, I realize that, it's an issue with linking the directories. I deleted ~/.virtualenvs folder and recreated all virtual envs.
$ ls -a ~/.virtualenvs
local-dev wdias-dev
$ rm -rf ~/.virtualenvs
$ which python3
/usr/local/bin/python3
$ mkvirtualenv local-dev --python=/usr/local/bin/python3
$ mkvirtualenv wdias-dev --python=/usr/local/bin/python3
Open the PyCharm again, and it works fine.
I couldn't get anything to work, so I cloned my conda env (see how), called it something else, and then set it in PyCharm to the new one.
For me, changing the paths in ~\venv\pyvenv.cfg made PyCharm recognize the new environment after bringing my projects to a new PC.
I had the same issue in Windows10. I was so frustrated, beacause everything seems looked OK. I've added PYTHONPATH, I've restarted Pycharm and deleted old virtualenv folders and created new... It did't work.
And at the end I have just opened Pycharm in an administrator mode and it works!
When creating a new project my interpreter was set to python 2.7 so I had to change that to python3 and everything works like a charm
I got the same problem with Pop OS 21.04 and Pycharm installed via Flatpack. So i remove it and installed via Snap and started working again.
I ended up having to install Python as an admin and make sure it installed to the C:\Program Files\Python310 folder. I think The option was to make sure it installed for all users. If I installed it under for user's appdata it wouldn't work.
Once I did that I was able to point pycharm to the C:\Program Files\Python310\ for the interpreter. Pretty annoying but finally got it working
I've solved it too. Uninstalled python 3.10, installed python 3.9. Changed the python interpreter to 3.9 through pycharm setting. Created a new virtual environment.
