I keep getting error "X" could not be resolved Pylance(reportMissingImports) [ln 1, Col8]
I AM in fact a beginner, the basic youtube "fixes" are NOT working
View Command Pallet ... NOT working
Terminal pip install .... NOT working
I am running the Zip install on my work computer and im guessing it has something to do with a directory. but i cant seem to figure it out. the bottom left corner shows the python version which is ( Pyhton 3.110a7 64-bit(windows store)
Pylance requires you to set the Python PATH:
If you're in Mac/linux, make use of :
which python3
And in windows:
where python
So that the path in which you're python is installed is returned
Copy that path.
Go to your vscode and open the settings.json file (CTRL + SHIFT + P, and type "settings.json" at search bar)
Add the following key to the json file
"python.defaultInterpreterPath": "/Users/YOURUSERNAME/opt/anaconda3/bin/python3"
This was just an example, the PATH could be something more like
"C:/users/YOURUSERNAME/anaconda3/bin/python3" in case you're using windows.
The following documentation from python for vscode provides more information about how to configure Python for Visual Studio Code:
https://code.visualstudio.com/docs/python/settings-reference
There’s a very comprehensive discussion on settings in VS Code here: https://stackoverflow.com/a/63211678/5709144.
In summary and with regard to this specific case, it’s better to change settings by going to (on a Mac) Code > Preferences > Settings.
Enter python.defaultInterpreterPath in the search box at the top of screen. The current path is shown in an editable text box.
Enter any path you like here - foobar, mother, whatever you like. It doesn’t matter as, if the path isn’t recognised by VS Code, VS Code lists those that are. The only reason you enter the path is to get the list of potential paths. Click on one of these accepted paths and you’re all set up.
As asked, your question doesn't specify whether or not your imported module is correctly installed. If it isn't, then this answer will not apply. However, if your code works as expected and you're getting a false warning, then you can ignore the warning by doing the following.
Create the file .vscode/settings.json in your current directory and then add the following:
"python.analysis.diagnosticsSeverityOverrides": {
"reportMissingImports": "none",
}
Be warned however that this will ignore all missing import warnings, not just the one you're trying to get rid of. Therefore, if you have any imports that are legitimately missing, the warning will not be there.
Also, on some occasions, you might have configured your environment by adding custom paths that Pylance can not detect.
In that case, you can use the python.analysis.extraPaths parameter to add more paths to your project, such as :
"python.analysis.extraPaths": ["app", "another/path/etc"]
(Source: https://dev.to/climentea/how-to-solve-pylance-missing-imports-in-vscode-359b)
If you are using the VS, Please go to the settings .. search for Advance path and then ADD it (/.source) it should solve the problem.
Hope you have installed the Pylance in your system correctly.

I am using PyCharm to work on a project. The project is opened and configured with an interpreter, and can run successfully. The remote interpreter paths are mapped properly. This seems to be the correct configuration, but PyCharm is highlighting my valid code with "unresolved reference" errors, even for built-in Python functions. Why don't these seem to be detected, even though the code runs? Is there any way to get PyCharm to recognize these correctly?
This specific instance of the problem is with a remote interpreter, but the problem appears on local interpreters as well.
File | Invalidate Caches... and restarting PyCharm helps.
Dmitry's response didn't work for me.
I got mine working by going to Project Interpreters, Selecting the "Paths" tab, and hitting the refresh button in that submenu. It auto-populated with something called "python-skeletons".
edit: screenshot using PyCharm 3.4.1 (it's quite well hidden)
There are many solutions to this, some more convenient than others, and they don't always work.
Here's all you can try, going from 'quick' to 'annoying':
Do File -> Invalidate Caches / Restart and restart PyCharm.
You could also do this after any of the below methods, just to be sure.
First, check which interpreter you're running: Run -> Edit Configurations -> Configuration -> Python Interpreter.
Refresh the paths of your interpreter:
File -> Settings
Project: [name] -> Project Interpreter -> 'Project Interpreter': Gear icon -> More...
Click the 'Show paths' button (bottom one)
Click the 'Refresh' button (bottom one)
Remove the interpreter and add it again:
File -> Settings
Project: [name] -> Project Interpreter -> 'Project Interpreter': Gear icon -> More...
Click the 'Remove' button
Click the 'Add' button and re-add your interpeter
Delete your project preferences
Delete your project's .idea folder
Close and re-open PyCharm
Open your project from scratch
Delete your PyCharm user preferences (but back them up first).
~/.PyCharm50 on Mac
%homepath%/.PyCharm50 on Windows
Switch to another interpreter, then back again to the one you want.
Create a new virtual environment, and switch to that environments' interpreter.
Create a new virtual environment in a new location -- outside of your project folder -- and switch to that environment's interpreter.
Switch to another interpreter altogether; don't switch back.
If you are using Docker, take note:
Make sure you are using pip3 not pip, especially with remote docker and docker-compose interpreters.
Avoid influencing PYTHONPATH. More info here: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000058690-Module-not-found-in-PyCharm-but-externally-in-Python .
If the above did not work for you, but you did find another trick, then please leave a comment.
In my case it was the directories structure.
My project looks like this:
+---dir_A
+---dir_B
+app
|
\-run.py
So right click on dir_b > "mark directory as" > "project root"
You have to mark your root directory as:
SOURCE ROOT (red),
and your applications:
EXCLUDED ROOT (blue).
Then the unresolved reference will disappear. If you use PyChram pro it do this for you automatically.
I find myself removing and re-adding the remote interpreter to fix this problem when Invalidating Caches or Refreshing Paths does not work.
I use vagrant and every once and awhile if I add a new VM to my multi-vm setup, the forwarded port changes and this seems to confuse PyCharm when it tries to use the wrong port for SSH. Changing the port doesn't seem to help the broken references.
If none of the other solutions work for you, try (backing up) and deleting your ~/.PyCharm40 folder, then reopening PyCharm. This will kill all your preferences as well.
On Mac you want to delete ~/Library/Caches/Pycharm40 and ~/Library/Preferences/PyCharm40.
And on Windows: C:\Users\$USER.PyCharm40.
Tested with PyCharm 4.0.6 (OSX 10.10.3)
following this steps:
Click PyCharm menu.
Select Project Interpreter.
Select Gear icon.
Select More button.
Select Project Interpreter you are in.
Select Directory Tree button.
Select Reload list of paths.
Problem solved!
Sorry to bump this question, however I have an important update to make.
You may also want to revert your project interpreter to to Python 2.7.6 if you're using any other version than that This worked for me on my Ubuntu installation of PyCharm 4.04 professional after none of the other recommendations solved my problem.
Much simpler action:
File > Settings > Project > Project Interpreter
Select "No interpreter" in the "Project interpreter" list
Apply > Set your python interpreter again > Click Apply
Profit - Pycharm is updating skeletons and everything is fine.
If you want to ignore only some "unresolved reference" errors, you can also tell it PyCharm explicitly by placing this in front of your class/method/function:
# noinspection PyUnresolvedReferences
You might try closing Pycharm, deleting the .idea folder from your project, then starting Pycharm again and recreating the project. This worked for me whereas invalidating cache did not.
I finally got this working after none of the proposed solutions worked for me. I was playing with a django rest framework project and was using a virtualenv I had setup with it. I was able to get Pycharm fixed by marking the root folder as the sources root, but then django's server would throw resolve exceptions. So one would work when the other wouldn't and vice versa.
Ultimately I just had to mark the subfolder as the sources root in pycharm. So my structure was like this
-playground
-env
-playground
That second playground folder is the one I had to mark as the sources root for everything to work as expected. That didn't present any issues for my scenario so it was a workable solution.
Just thought I'd share in case someone else can use it.
It could also be a python version issue. I had to pick the right one to make it work.
None of the answers solved my problem.
What did it for me was switching environments and going back to the same environment. File->Settings->Project interpreter
I am using conda environments.
Mine got resolved by checking inherit global site-packages in PyCharm
File -> Settings -> Project Interpreter -> Add Local Interpreter -> Inherit global site-packages
I closed all the other projects and run my required project in isolation in Pycharm. I created a separate virtualenv from pycharm and added all the required modules in it by using pip. I added this virtual environment in project's interpreter. This solved my problem.
Geeze what a nightmare, my amalgamation of different StackOVerflow answers:
Switch to local interpreter /usr/bin/pythonX.X and apply
View paths like above answer
Find skeletons path. Mine was (/home/tim/Desktop/pycharm-community-2016.2.3/helpers/python-skeletons)
Switch back to virt interpreter and add the skeletons path manually if it didn't automatically show up.
None of the above solutions worked for me!
If you are using virtual environment for your project make sure to apply the python.exe file that is inside your virtual environment directory as interpreter for the project (Alt + Ctrl + Shift + S)
this solved the issue for me.
In my case the inspection error shows up due to a very specific case of python code.
A min function that contains two numpy functions and two list accesses makes my code inspection give this kind of errors.
Removing the 'd=0' line in the following example gives an unresolved reference error as expected, but readding doesn't make the error go away for the code inspector. I can still execute the code without problems afterwards.
import numpy as np
def strange(S, T, U, V):
d = 0
print min(np.abs(S[d]), np.abs(T[d]), U[d], V[d])
Clearing caches and reloading list of paths doesn't work. Only altering the code with one of the following example patches does work:
Another ordering of the 'min' parameters: schematically S U T V but not S T U V or T S U V
Using a method instead of the function: S[d].abs() instead of np.abs(S[d])
Using the built-in abs() function
Adding a number to a parameter of choice: U[d] + 0.
My problem is that Flask-WTF is not resolved by PyCharm. I have tried to re-install and then install or Invalidate Cache and Restart PyCharm, but it's still not working.
Then I came up with this solution and it works perfectly for me.
Open Project Interpreter by Ctrl+Alt+S (Windows) and then click Install (+) a new packgage.
Type the package which is not resolved by PyCharm and then click Install Package. Then click OK.
Now, you'll see your library has been resolved.
In PyCharm 2020.1.4 (Community Edition) on Windows 10 10.0. Under Settings in PyCharm: File > Settings > Project Structure
I made two changes in Project Structure:
main folder marked as source and
odoo folder with all applications I excluded
Screenshot shows what I did.
After that I restarted PyCharm: File > Invalidate Caches / Restart...
Unresolved references error was removed
Invalidating the cache as suggested by other answers did not work for me. What I found to be the problem in my case was that PyCharm was marking init.py files of Python packages as text and thus not including them in the analysis which means python resolving was not working correctly.
The solution for me was to:
Open PyCharm settings
Navigate to Editor -> File Types
Find Python and add __init__.py to the list of python files
or Find Text and delete __init__.py from the list of text files
To add yet another one: None of the solutions involving the Python Interpreter tab helped, however, I noticed I had to set Project Dependencies: In the project that had unresolved reference errors, none of the dependencies were checked. Once I checked them, the relevant errors disappeared. I don't know why some are checked to begin with and others are not.
If you are using vagrant the error can be caused by wrong python interpreter.
In our vagrant we are using pyenv so I had to change Python Interpreter path path from /usr/bin/python to /home/vagrant/.pyenv/versions/vagrant/bin/python
I have a project where one file in src/ imports another file in the same directory. To get PyCharm to recognize I had to to go to File > Settings > Project > Project Structure > select src folder and click "Mark as: Sources"
From https://www.jetbrains.com/help/pycharm/configuring-folders-within-a-content-root.html
Source roots contain the actual source files and resources. PyCharm uses the source roots as the starting point for resolving imports
I had to go to File->Invalidate Caches/Restart, reboot Ubuntu 18.04 LTS, then open Pycharm and File-> Invalidate Caches/Restart again before it cleared up.
For me it helped:
update your main directory "mark Directory as" -> "source root"
#kelorek works for me, but before, in interpereter paths I had to add some path.
lets say
from geometry_msgs.msg import Twist
is underline as error, then in remote machine in python run:
help("geometry_msgs")
at the end there will be path lets say :
/opt/ros/foxy/lib/python3.8/site-packages/geometry_msgs/__init__.py
so to Your intepreter pycharm path add
/opt/ros/foxy/lib/python3.8/site-packages
Hope it will help You and it helps me :)
I had the same symptoms. In my instance the problem source was that I had set
idea.max.intellisense.filesize=50 in the custom properties.
I could resolve it by setting it to 100.

I downloaded Visual Studio Code the other day and I decided to use it with pylint.
For some odd reason I couldn't set the python interpreter to python 3 from the palette (Shift + Ctrl + P) but I set the path to it from the settings and it seems to have done the job. However, pylint underlines almost everything. All of my imports are underlined with the error message:
[pylint] E0401:Unable to import 'my.import'
I read a couple of threads on this topic and the main suggestions are to set the correct python path and path to pylint, which I have done with 0 success. I tried removing it pip3 remove pylint and reinstalling it, however, it still did not fix my issue.
You may try setting "python.linting.pylintPath" key separately.
In settings.json you can set like this;
"python.linting.pylintPath": "/home/user/.local/bin/pylint"
user will be your user name of course
if you use linux and want to find exact location of pylint you can run which pylint command in terminal
To solve this issue, you can set the path to your python installation in preferences-> settings python.pythonPath.
I want to test some python files in a project before installing them. For this I entered the folder to be installed in my vscode workspace settings as follows:
"python.autoComplete.extraPaths": [
"${workspaceRoot}/lib_python/release"
]
Now I have a test file in my workspace that imports from the above mentioned folder. Suggestions work fine, it also gives me definitions while hovering with the mouse over a class name from the imported file. However, half my code is underlined in red, because pylint says it does not know the definitions and cannot import.
Question: Is there a way to also make whatever part of the python plugin by Don Jayamanne is responsible for the red underlining find the additional import folders?
So what worked for me now is to set additional paths in a .env file in the project's root folder. This file will be read by the python extension of vscode.
Example:
PYTHONPATH=./lib_python/release
In User Settings -> Extensions be sure python command is the right one. On my Mac, python refers to Python 2.x, however python3 refers to Python 3.X. I simply changed VSCode's python command to python3 and this resolved my issue.
I am beginning to look at python, so when I found a tutorial it said that the first thing to do would be to download python from www.python.org/downloads/
Now when I downloaded python 3, I then started the installation and got to
Why would I want to "Add Python 3.5 to PATH"? What is PATH? Why is it not ticked by default?
PATH is an environment variable in Windows. It basically tells the commandline what folders to look in when attempting to find a file. If you didn't add Python to PATH then you would call it from the commandline like this:
C:/Python27/Python some_python_script.py
Whereas if you add it to PATH, you can do this:
python some_python_script.py
Which is shorter and neater. It works because the command line will look through all the PATH folders for python and find it in the folder that the Python installer has added there.
The reason it's unticked by default is partly because if you're installing multiple versions of Python, you probably want to be able to control which one your commandline will open by default, which is harder to do if both versions are being added to your PATH.
In addition to what #SuperBiasedMan stated, you can edit your PATH in Windows by hitting Start > Run, then type sysdm.cpl.
From there, navigate to Advanced tab and then hit Environment Variables.
In the lower section, where it says 'System variables', find the one named PATH and double click it. Note that it would be easier to copy and paste it to a notepad or something. The separator as you can see is a semi-colon.
Any path that you add to this variable, will be looked when you type any command in a cmd window or through the 'Run' command line.
That's the same concept as in Linux, I just pointed out how it can be edited.
This shows the way if you haven't add python to PATH(By the way, the python.exe is in my Python directory)
This is the way if you add python to a PATH
