PyCharm shows unresolved references error for valid code

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)

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.

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

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.

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.

Geeze what a nightmare, my amalgamation of different StackOVerflow answers:

1. Switch to local interpreter /usr/bin/pythonX.X and apply
2. View paths like above answer
3. Find skeletons path. Mine was (/home/tim/Desktop/pycharm-community-2016.2.3/helpers/python-skeletons)
4. Switch back to virt interpreter and add the skeletons path manually if it didn't automatically show up.

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.

1. Open Project Interpreter by Ctrl+Alt+S (Windows) and then click Install (+) a new packgage.

2. 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

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.

Help->Edit Custom Properties

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.

Mine got resolved by checking inherit global site-packages in PyCharm

File -> Settings -> Project Interpreter -> Add Local Interpreter -> Inherit global site-packages
