whenever I try to import matplotlib or matplotlib.pyplot in VS Code I get the error in the title:
Import "matplotlib" could not be resolved from source Pylance(reportMissingModuleSource)
or
Import "matplotlib.pyplot" could not be resolved from source Pylance(reportMissingModuleSource)
The hyperlink of the reportMissingModuleSource sends me to https://github.com/microsoft/pylance-release/blob/main/DIAGNOSTIC_SEVERITY_RULES.md#diagnostic-severity-rules, where it says:
«Diagnostics for imports that have no corresponding source file. This happens when a type stub is found, but the module source file was not found, indicating that the code may fail at runtime when using this execution environment. Type checking will be done using the type stub.»
However, from the explanation I don’t understand exactly what’s wrong and what I should do to fix this, can someone help me with this?

I can reproduce your question when I select a python interpreter where doesn’t exist matplotlib:
So, the solution is opening an integrated Terminal then run pip install matplotlib. After it’s installed successfully, please reload window, then the warning should go away.

I had the same issue. Sometimes it’s back to multiple versions of python on your device. You just need to change the path. Make sure the correct Python interpreter is selected in your IDE.
In vscode Press CTRL + Shift + P or (⌘ + Shift + P on macOS) to open the command palette. Then type Python select interpreter in the search field and choose the right version.

I have the same issue — I did two things and its working now
-
Check if there is some earlier versions of python installed on your machine — if yes then remove and reinstall the latest one
-
Second install the Microsoft C++ Build Tools
https://visualstudio.microsoft.com/visual-cpp-build-tools/
Restart the app and run again.

I was getting the same problem and realised the package install path for my active virtual env wasn’t listed in sys.path
after appending this location to sys.path my .ipynb was able to import matplotlib

You will likely encounter the error message ‘Import “flask” could not be resolved from source Pylance (reportMissingModuleSource)‘ when working with Python. If you are facing the same problem, don’t worry, this article will help you overcome this problem.
How did this error occur?
The cause of this error is that the ‘flask’ module is not installed in the required environment.
This error started appearing as soon as you used the import statement. To illustrate, you can see the example below:
As you can see, we cannot import the module ‘flask’ in this situation.
Explain more understandably: You work on your computer and install many different versions of Python for different projects. The error message tells you that ‘flask’ is not installed in the current Python environment in use.
You need to install the flask module. Here is the procedure we recommend to fix this problem:
- First, you need to create a Virtual Environment on your terminal.
- Use the pip install flask command to install the flask module.
- Use the key combination: CTRL+SHIFT+P.
- Search “Python: Select Interpreter”.
- Select your Virtual Environment.
Virtual Environment in Python is a virtual environment. Just like virtual machines (Virtual Machine), Virtual Environment establishes a virtual environment, allowing you to freely perform installation, removal, and installation of different versions of Python packages without fear of affecting the available projects.
To create a Virtual Environment, open the terminal in your project and the following command:
pip install virtualenvTo check if the installation of module ‘virtualenv’ has been successful, you can use the pip list command. The result will show a list of installed packages.
Now you can create a virtual environment and use that virtual environment with the following two commands:
::create a virtual environment called env
python -m venv env
::activate the virtual environment in your project
.envscriptsactivate
Using the key combination CTRL+SHIFT+P, search for “Python: Select Interpreter”, then select the python environment you have virtualized for your project.
Finally, run the install command for the ‘flask’ module.
pip install flaskEverything seems to be working smoothly, and the error no longer occurs.
Summary
In conclusion, the error “Import “flask” could not be resolved from source Pylance (reportMissingModuleSource)” has been solved. You must install the ‘flask’ module for the required environment before you can use it. That’s the end of this article. We hope the above information is clear and helpful to you.

To Solve Import “flask” could not be resolved from source Pylance (reportMissingModuleSource) Error just make sure that VSCode is using the virtualenv as your python interpreter, otherwise it will not be able to pick up the packages that you installed inside this virtualenv. To do so, click on the Python interpreter in your bottom bar, you should get a list of possible python interpreters including your virtualenv.
Solution 1
make sure that VSCode is using the virtualenv as your python interpreter, otherwise it will not be able to pick up the packages that you installed inside this virtualenv.
To do so, click on the Python interpreter in your bottom bar, you should get a list of possible python interpreters including your virtualenv.
Solution 2
I had a similar issue while trying to import flask on vscode. I fixed it by using anaconda. Simply you install the flask module in your created environment.
How to create a virtual env in anaconda:
1. On the left sidebar, click on environments.
2. Click create (at the bottom).
3. At the pop-up window, give your vir.env a name and select the language version.
4. Once created, you can start installing different modules in your environment.

Когда я пишу
from flask import Flask
Под флягой появляется одна желтая строка, в которой говорится, что Импорт «фляги» не может быть разрешен из исходного Pylance (reportMissingModuleSource) . Также я могу успешно работать с этим пакетом. Но дело в том, что я не очень хорошо умею использовать автоматические подсказки для классов и методов.
Дальше:
- Я проверил, что колба успешно установлена.
- Также я посетил эту ветку https://github.com/microsoft/pylance-release/issues / 236
И я настроил свой < sizessettings.json в vscode следующим образом:
"python.analysis.extraPaths": [
"/media/sarimurrab/New Volume/COURSES/Flask/FlaskMigrateforDatabaseMigrations/2"
]
Но все же не удалось устранить ошибку.

Когда я не установил модуль «flask» в среде Python, которая в настоящее время используется в VSCode:
Используйте команду «pip --version», чтобы проверить источник средства установки модуля «pip», модуль установлен в этом месте:
Затем мы можем использовать команду «pip show flask«, чтобы проверить место установки модуля «flask»: (Он проверяет, соответствует ли место установки модуля среде Python, отображаемой в нижнем левом углу VSCode .)
Если сообщение «reportMissingModuleSource» все еще отображается здесь, перезагрузите VS Code.

Вы используете Virtualenv? Если это так, убедитесь, что VSCode использует virtualenv в качестве вашего интерпретатора python, иначе он не сможет получить пакеты, которые вы установили внутри этого virtualenv.
Для этого щелкните интерпретатор Python в нижней панели, вы должны получить список возможных интерпретаторов Python, включая ваш virtualenv.
