Adding to PYTHONPATH in VS Code - python

I'm trying to add the src folder to my PYTHONPATH i.E. do the same thing as Mark directory as sources root in PyCharm.
I've looked at the solutions to Visual Studio Code - How to add multiple paths to python path? but the solutions shown there do not work for me.
I've set up my minimal example as follows shown in the screenshot below:
My understanding would be that having a .env file with PYTHONPATH="./src;${PYTHONPATH}" would add the src file to the path.
Nevertheless, when running the code runner or when running python change_pyhton_path.py src is not part of the PYTHONPATH and the direct import from src fails.
I do have setting "python.envFile": "${workspaceFolder}/.env".
In pyCharm on the other hand everything works as it should after hitting Mark directory as source on src.
Thanks for helping out!

in your settings.json add:
"terminal.integrated.env.windows": {
"PYTHONPATH": "full python path here"
}

if you have problems with importing modules and you are using code-runner, try to add
"code-runner.fileDirectoryAsCwd": true
to your settings.json file

If you are trying to get auto complete working from your source directory, you could add to the PYTHONPATH environment variable as you are doing. You can also go the "vscode native" route, as there is a configuration. Open your workspace settings and add the following line:
"python.autoComplete.extraPaths": ["./src"]
NOTE: Avoid setting this at the user level as each project differs in where the source code lives

I dont know much but the json PYTHONPATH setting above looks like it would work as the json.settings file is definatly going to nead to know about your interpreter. Once you have a Python terminal prompt you have to run pythons pip file to integrate all the neccesary libraries . VS Code itself tells you to go to the command pallete and install either a venv virtual environment or create a conda (from anaconda or miniconda) set up for it. I am trying to do it myself so once I crack it I'll have more info.

How to set PYTHONPATH for all tools in Vscode (on Windows)?

I have a folder mysrc in my project root and I'd like to make all tools of VScode work with import mysrc. The only way I found to make it work is to put the full absolute path PYTHONPATH=<fullpath_to_workfolder> in the .env file. But ideally I'd like to use relative paths to the workfolder.
How can I do that?
All suggestions I found (also here) somehow do not work. ${workspaceFolder} is empty. PYTHONPATH=. does not work. Ideally I'd configure a single PYTHONPATH and not for every tool (terminal, notebooks, mypy, ...). And even my solution for whatever reason duplicates PYTHONPATH=<fullpath_to_workfolder>;<fullpath_to_workfolder> on Windows when I inspect this variable in my code. I believe on Linux I did not have issues.
I'm not sure if this is what you want, but you could create a batch file with the following lines:
#echo off
set PYTHONPATH=%cd%
"%LOCALAPPDATA%\Programs\Microsoft VS Code\Code.exe"
(assuming default VS Code installation directory — you might have to change the last line if you installed it in another directory.)
This would call VS Code with the PYTHONPATH environment variable set to the directory from where you call it.
You can confirm this by opening a terminal window in VS Code and typing echo %PYTHONPATH%. All processes spawned from VS Code will inherit the environment variables, so this should work for all tools.
If you copy the batch script to another project and call it from there, all tools would then use that directory.
Sorry, but it works when I add these in the .env file:
PYTHONPATH=.\
or
PYTHONPATH=.
Could you reconfirm it?
Update:
.env file has no influence on the Jupyter NoteBook, but it works on linters, formatters, IntelliSense, and testing tools.
You can configure this to achieve it:
"jupyter.notebookFileRoot": "${workspaceFolder}",

imports issues in vscode (Python)

I'm trying to write a python library with the following structre on vsc. When I run tests I got an error no module named pytrader. pytrader is a python package it has an init on it. In pycharm i used to set the src folder as the source directory and everything works. Any help thank you
enter image description here
The action of set the src folder as the source directory in the PyCharm is to add the src folder path to the PYTHONPATH.
In the VSCode, it has no way to add it directly, but it's possible to edit it when you debugging, you can add this in the launch.json file:
"env": {"PYTHONPATH":"${workspaceRoot}/src"},
And you can add it directly in the python file like this:
sys.path.append("D:\\TestPlace")

How do I get into the environment VS Code is using for pylance?

I'm using pylance to check my Python code. It tells me
Import "astor" could not be resolved
When I switch to the terminal within VS Code:
I'm pretty certain that the issue is that it uses another environment. I'm using pyenv by default and I would like if vscode would use the same environment. But at the very least I need to be able to access the environment it is using to install packages.
Interestingly, the status bar seems to show something else, because in that environment I have astor installed:
I found this link that informs us that we should add an extra path.
These extra roots must be specified to the language server. The
easiest way to do this (with the VS Code Python extension) is to
create a workspace configuration which sets
python.analysis.extraPaths. For example, if a project uses a sources
directory, then create a file .vscode / settings.json in the workspace
with the contents:
{
"python.analysis.extraPaths": ["./sources"]
}
https://github.com/microsoft/pylance-release/blob/master/TROUBLESHOOTING.md#unresolved-import-warnings
Another easy way to solve this on VSCODE:
ctrl + ','
type "extrapaths"
Down you should have something like "add element" (I have VSCode on Spanish so in my case I have "Agregar elemento")
type './sources/'
Also if you have problems importing local files, you can do the same thing and add your working directory path to solve the problem :) just add 'C: your working directory goes here' in addition to './sources' in the same way ;)
I found one thing resolved my issue same as yours
Go to your working env(mine is pipenv shell), then pip show 'yourmodule' to check your module is installed or not
If its installed copy Location: path
Go to settings ctrl +','
Type extrapaths
Add Item paste the path string you copied and ok.
We have added actual installed path as additional import search resolution path, so this path will be scanned for imports
Now your module should be resolved. This worked for me.

Pylint "unresolved import" error in Visual Studio Code

I am using the following setup
macOS v10.14 (Mojave)
Python 3.7.1
Visual Studio Code 1.30
Pylint 2.2.2
Django 2.1.4
I want to use linting to make my life a bit easier in Visual Studio Code. However, for every import I have states "unresolved import". Even on default Django imports (i.e. from django.db import models).
I presume it is because it is not seeing the virtual environment Python files.
Everything works just fine, but it's starting to get annoying.
The interpreter choices I have are all system versions of Python. It does not seem to see my virtual environment Python at all (it is not in the same directory as my workspace, so that part makes sense).
If I set up the python.PythonPath in the settings.json file, it just ignores it and does not list my virtual environment path as an option. I also tried setting it up in my global Python settings, but it also does not show up.
Is there a quick fix to get it working?
The accepted answer won't fix the error when importing own modules.
Use the following setting in your workspace settings .vscode/settings.json:
"python.autoComplete.extraPaths": ["./path-to-your-code"],
Reference: Troubleshooting, Unresolved import warnings
In your workspace settings, you can set your Python path like this:
{
"python.defaultInterpreterPath": "/path/to/your/venv/bin/python",
}
Alternative way: use the command interface!
Cmd/Ctrl + Shift + P → Python: Select Interpreter → choose the one with the packages you look for:
This issue has already been opened on GitHub:
Python unresolved import issue #3840
There are two very useful answers, by MagnuesBrzenk and SpenHouet.
The best solution for now is to create a .env file in your project root folder. Then add a PYTHONPATH to it like this:
PYTHONPATH=YOUR/MODULES/PATH
And in your settings.json add:
"python.envFile": ".env"
When I do > reload window that fixes it.
Reference: Python unresolved import issue #3840, dkavraal's comment
None of the solutions worked except this one. Replacing "Pylance" or "Microsoft" in the settings.json solved mine.
"python.languageServer": "Jedi"
You need to select the interpreter associated with the virtual environment.
Click here (at the bottom status bar):
And just select the virtual environment you are working with. Done.
Sometimes, even with the interpreter selected, it won't work. Just repeat the process again and it should solve it.
If you have this code in your settings.json file, delete it:
{
"python.jediEnabled": false
}
If you are more visual like myself, you can use the Visual Studio Code configurations in menu File → Preferences → Settings (Ctrl + ,). Go to Extensions → Python.
In the section Analysis: Disabled, add the suppression of the following message: unresolved-import:
I was able to resolved this by enabling jedi in .vscode\settings.json
"python.jediEnabled": true
Reference from https://github.com/Microsoft/vscode-python/issues/3840#issuecomment-456017675
I wonder how many solutions this problem have (or have not), I tried most of the above, nothing worked, the only solution that worked is to set the python language server to Jedi, instead of Microsoft in the settings.json file:
"python.languageServer": "Jedi"
None of the previous answers worked for me. Adding both of the lines below to my settings.json file did, however.
"python.analysis.disabled": [
"unresolved-import"
],
"python.linting.pylintArgs": ["--load-plugin","pylint_protobuf"]
The first line really just hides the linting error. Certainly not a permanent solution, but de-clutters the screen.
This answer gave me the second line: VS Code PyLint Error E0602 (undefined variable) with ProtoBuf compiled Python Structure
Maybe someone who understands Python more than me can explain that one more.
Okay, so 2 years down the line, I have ran into this annoying problem. All I can seen here are some really complicated workarounds. Here are easy to follow steps for anyone else who might just run into this later on:
at the bottom of VS Code where you see the Python version listed, just click there
Select Interpreter windows is going to appear
click on the first option that says "Select Interpreter Path" and navigate to the folder path which has your Virtual Environment
That's all you need to do and avoid tampering with those settings in VS Code which might get very complicated if not handled with caution.
My solution
This solution is only for the current project.
In the project root, create folder .vscode
Then create the file .vscode/settings.json
In the file setting.json, add the line (this is for Python 3)
{
"python.pythonPath": "/usr/local/bin/python3",
}
This is the example for Python 2
{
"python.pythonPath": "/usr/local/bin/python",
}
If you don't know where your Python installation is located, just run the command which python or which python3 on the terminal. It will print the Python location.
This example works for dockerized Python - Django.
I was facing the same problem while importing the project-related(non standard) modules.
Detailed explanation of the problem
Directory structure:
Project_dir:
.vscode/settings.json
dir_1
> a
> b
> c
dir_2
> x
> y
> z
What we want:
Project_dir
dir_3
import a
import y
Here "import a" and "import y" fails with following error:
Import "dir_1.a" could not be resolvedPylancereportMissingImports
Import "dir_2.y" could not be resolvedPylancereportMissingImports
What worked for me:
Appending the top directory which contains the modules to be imported.
In above example add the follwoing "Code to append" in ".vscode/settings.json"
Filename:
.vscode/settings.json
Code to append:
"python.analysis.extraPaths": [dir_1, dir_2]
The solution from Shinebayar G worked, but this other one is a little bit more elegant:
Copied from Python unresolved import issue #3840:
Given the following example project structure:
workspaceRootFolder
.vscode
... other folders
codeFolder
What I did to resolve this issue:
Go into the workspace folder (here workspaceRootFolder) and create a .env file
In this empty .env file, add the line PYTHONPATH=codeFolder (replace codeFolder with your folder name)
Add "python.envFile": "${workspaceFolder}/.env" to the settings.json
Restart Visual Studio Code
To me the problem was related with the project that I was working on. It took me a while to figure it out, so I hope this helps:
Original folder structure:
root/
__init__.py # Empty
folder/
__init__.py # Empty
sub_folder_b/
my_code.py
sub_folder_c/
another_code.py
In another_code.py:
from folder.sub_folder_b import my_code.py
This didn't trigger the intellisense in Visual Studio Code, but it did execute OK.
On the other hand, adding "root" on the import path, did make the intellisense work, but raised ModuleNotFoundError when executing:
from root.folder.sub_folder_b import my_code.py
The solution was to remove the _init_.py file inside the "folder" directory, leaving only the _init_.py located at /root.
This works for me:
Open the command palette (Ctrl + Shift + P) and choose "Python: Select Interpreter".
Doing this, you set the Python interpreter in Visual Studio Code.
None of the answers here solved this error for me. Code would run, but I could not jump directly to function definitions. It was only for certain local packages. For one thing, python.jediEnabled is no longer a valid option. I did two things, but I am not sure the first was necessary:
Download Pylance extension, change python.languageServer to "Pylance"
Add "python.analysis.extraPaths": [ "path_to/src_file" ]
Apparently the root and src will be checked for local packages, but others must be added here.
I am using the following setup: (in Apr 2021)
macos big sur
vscode
Anaconda 3 (for environment)
And I faced this error during starting of the Django.
So, I follow these steps and this error is resolved.
Steps are given in these screenshots:
Open settings (workspace)
Follow this screenshot to open Python Path
Now, click Edit in settings.json
Make path like given in this screenshot /opt/anaconda3/bin/python
5. Now, save this settings.json file.
6. Restart the vscode
Also, intellisense might not work for some time hold on wait for some time and then restart again then vscode reads file for new path.
That happens because Visual Studio Code considers your current folder as the main folder, instead of considering the actual main folder.
The quick way to fix is it provide the interpreter path to the main folder.
Press Command + Shift + P (or Ctrl + Shift + P on most other systems).
Type Python interpreter
Select the path where you installed Python in from the options available.
Changing
Python:Language Server
to 'Jedi' worked for me.
It was 'Windows' initially.
For me, it worked, if I setup the paths for python, pylint and autopep8 to the local environment paths.
For your workspace add/change this:
"python.pythonPath": "...\\your_path\\.venv\\Scripts\\python.exe",
"python.linting.pylintPath": "...\\your_path\\.venv\\Scripts\\pylint.exe",
"python.formatting.autopep8Path": "...\\your_path\\.venv\\Scripts\\autopep8.exe",
Save and restart VS Code with workspace.
Done!
I have a different solution: my Visual Studio Code instance had picked up the virtualenv stored in .venv, but it was using the wrong Python binary. It was using .venv/bin/python3.7; using the switcher in the blue status bar.
I changed it to use .venv/bin/python and all of my imports were resolved correctly.
I don't know what Visual Studio Code is doing behind the scenes when I do this, nor do I understand why this was causing my problem, but for me this was a slightly simpler solution than editing my workspace settings.
In case of a Pylint error, install the following
pipenv install pylint-django
Then create a file, .pylintrc, in the root folder and write the following
load-plugins=pylint-django
I have faced this problem in three ways. Although for each of them a solution is available in the answers to this question, I just thought to put it all together.
First I got an "Unresolved Import" while importing some modules and I noticed that my installations were happening in global pip instead of the virtual environment.
This issue was because of the Python interpreter. You need to select the interpreter in Visual Studio Code using Shift + Ctrl + P and then type Select Python Interpreter. Select your venv interpreter here.
The second issue was: The above change did not resolve my issue completely. This time it was because of file settings.json. If you don't have the settings.json file in your project directory, create one and add the following line in that:
{
"python.pythonPath": "apis/bin/python"
}
This will basically tell Visual Studio Code to use the Python interpreter that is in your venv.
The third issue was while importing a custom Python module or file in another program. For this you need to understand the folder structure. As Python in venv is inside bin, you'll need to specify the folder of your module (most of the time the application folder). In my case it was app,
from app.models import setup_db
Verbally, import setup_db from models.py resides in the app folder.
If you are using pipenv then you need to specify the path to your virtual environment.in settings.json file.
For example :
{
"python.pythonPath":
"/Users/username/.local/share/virtualenvs/Your-Virual-Env/bin/python"
}
This can help.
If someone happens to be as moronic as me, the following worked.
Old folder structure:
awesome_code.py
__init__.py
src/
__init__.py
stuff1.py
stuff2.py
New structure:
awesome_code.py
src/
__init__.py
stuff1.py
stuff2.py
How to avoid warning
Please note that this is just skipping the warning not resolving it.
First of all open visual studio code settings in json and add following arguments after "[python]":{}
"python.linting.pylintArgs": ["--rep[![enter image description here][1]][1]orts", "12", "--disable", "I0011"],
"python.linting.flake8Args": ["--ignore=E24,W504", "--verbose"]
"python.linting.pydocstyleArgs": ["--ignore=D400", "--ignore=D4"]
This has helped me to avoid pylint warnings in VSCode.
I have resolved import error by Ctrl + Shift + P.
Type "Preferences settings" and select the option Preferences Open Settings (JSON)
And add the line "python.pythonPath": "/usr/bin/"
So the JSON content should look like:
{
"python.pythonPath": "/usr/bin/"
}
Keep other configuration lines if they are present.
This should import all modules that you have installed using PIP for autocomplete.

Python works in PyCharm but not from terminal

I recently figured out how to import modules for unittesting in python. As a solution to this, I use:
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))
from Dev.test import someclass
This works fine while running in PyCharm and I get the expected output. However, when I run from terminal I run into an error:
ImportError: No module named Dev.test
I have the init files where they are supposed to be but I'm lost as to why this is working in PyCharm but not from the terminal. I have not changed my path or anything in PyCharm as this code is supposed to be able to run with minimal modifications on other machines. Any idea as to why this is happening and what I might be able to do to fix it?
My folder structure is as follows
-Current
-Dev
-__init__.py
-test
- __init__.py
-someclass.py
-Tests
-__init__.py
-someunittest.py
I have tried running someunittest from the main folder as well as with a complete path but it only works in PyCharm
sys.path.append(os.getcwd()[:os.getcwd().index('Dev')])
I added this to my imports and it seems to have solved the problem. However, this doesn't seem like it would be the right way to do it; it will do for now.
When running a script from within PyCharm, it runs it in an environment with PYTHONPATH set to the list of all the folders that are marked "Sources Root" (with a blue folder icon) in the project explorer.
Outside of PyCharm, PYTHONPATH is not normally set. The first entry in sys.path refers to the current working directory where the script was run from. As long as you run your script with your terminal's working directory as the folder containing Dev, it should be able to find the Dev.test module, regardless of the extra entry added to sys.path.
Once you get the working directory correct, you should be able to remove the sys.path hack.
What #codewarrior has said about the PyCharm setting its own PYTHONPATH is correct. But sys.path didn't have my current working directory. So to get around this problem, I updated my PYTHONPATH (or you can edit sys.path).
Setting PYTHONPATH
export PYTHONPATH=$PYTHONPATH:`pwd` (OR your project root directory)
Updating sys.path
import sys
sys.path.insert(0,'<project directory>') OR
sys.path.append('<project directory>')
You can use insert/append based on the order in which you want your project to be searched.
HTH.
Pycharm uses a virtual environment. When you try run your program in your terminal this enviroment isn't active.
You need to build or upload your enviroment Pycharm with your libraries.
cd to the directory project and write in terminal:
source venv/bin/activate
I too have had this issue - and the PYTHONPATH setting set by PyCharm did seem to be the issue.
My alternative (as I was nearly finished writing the code) was to generate a setup.py - and install the classes/structure in my local virtual Python environment.
I would recommend trying out $ pip install . in your source directory. This will install your own packages for your project.
To add to similar answers here, PyCharm is doing some extra config for you before running your script. If adding your sources root to PYTHONPATH doesn't work then examine your run configuration in PyCharm for the script in question, there will likely be some more behind the scenes magic at play.
I had similar problem. I think the problem is that Pycharm modifies PYTHONPATH so before running your script:
cd to the file where python file resides
run export PYTHONPATH=.
run the script
You can also create "main" python file where you set the python path and then call the other modules
