No module named 'pip._internal.models.target python'

I can install packages with the terminal but Python can't use them. When I try to install them with the PyCharm package manager, I get this error: No module named 'pip._internal.models.target python'. Every solution I found on the internet relates only to pip_internal but not more.
I used the command pip install pyside6 and it worked without problems.
The Python and the PyCharm route is also in PATH.
The reinstalling of pip didn't help much either.
I think there is maybe a compiler problem, but I don't know enough for a good supposition.

Here are a few things you can try to resolve the issue:
Check the Python interpreter in PyCharm: Ensure that the Python interpreter in PyCharm is the same as the one you used when installing the package with pip. To check the interpreter, go to File > Settings > Project: your_project_name > Python Interpreter. Make sure the interpreter selected here is the same one you used in the terminal.
Check the project interpreter path: In the same settings window, click the gear icon and select "Show all". Then select the interpreter you are using and make sure the interpreter path matches the one you used in the terminal.
Check the PyCharm terminal: Make sure you are using the same terminal in PyCharm that you used when installing the package with pip. To do this, go to View > Tool Windows > Terminal and ensure that the terminal you are using is the same as the one you used in the terminal.
Try installing the package directly in PyCharm: Instead of using pip in the terminal, try installing the package directly in PyCharm using the package manager. To do this, go to File > Settings > Project: your_project_name > Python Interpreter, select the interpreter you are using, and click the "+" icon to install the package.

ModuleNotFoundError: No module named 'pyshark' [duplicate]

In PyCharm, I've added the Python environment /usr/bin/python. However,
from gnuradio import gr
fails as an undefined reference. However, it works fine in the Python interpreter from the command line.
GNURadio works fine with python outside of Pycharm. Everything is installed and configured how I want it.
Gnuradio is located at /usr/local/lib/python2.7/site-packages/gnuradio
Also:
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/gnuradio

Adding a Path
Go into File → Settings → Project Settings → Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
But I don't know the path..
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.

You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project

For me, it was just a matter of marking the directory as a source root.

Add path in PyCharm 2017
File -> Settings (or Ctrl+Alt+S) -> Project -> Project Interpreter
Show all
Select bottom icon on the right side
Click on the plus button to add new path to your module

My version is PyCharm Professional edition 3.4, and the Adding a Path part is different.
You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.

DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root

In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:

For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.

As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')

On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.

I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.

In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package

For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.

How to I fix the “ModuleNotFound” error when importing PyQt5? [duplicate]

I installed bottle on Python 3.4 with pip install. In the terminal, when I do:
$ python3.4
>>>import bottle # shows no import error
>>>
but when I do it in PyCharm, it says:
import bottle ImportError: No module named 'bottle'

in your PyCharm project:
press Ctrl+Alt+s to open the settings
on the left column, select Project Interpreter
on the top right there is a list of python binaries found on your system, pick the right one
eventually click the + button to install additional python modules
validate

In some cases no "No module ..." can appear even on local files. In such cases you just need to mark appropriate directories as "source directories":

The settings are changed for PyCharm 5+.
Go to File > Default Settings
In left sidebar, click Default Project > Project Interpreter
At bottom of window, click + to install or - to uninstall.
If we click +, a new window opens where we can decrease the results by entering the package name/keyword.
Install the package.
Go to File > Invalidate caches/restart and click Invalidate and Restart to apply changes and restart PyCharm.
Settings:
Install package:

I am using Ubuntu 16.04. For me, it was the incorrect interpreter, which was by default using the virtual interpreter from the project.
So, make sure you select the correct one, as the pip install will install the package to the system Python interpreter.

PyCharm 2019.3, my solution is below:

For me, none of the above worked, and curiously even within one file some imports worked, some didn't:
from folder1.folder2.folder3.my_python_file import this_function # worked
from folder1.folder2.folder3.my_python_file import that_function # didn't work
Follow the above advice, but if it doesn't fix it additionally, (in PyCharm) click File >> Repair IDE and confirm all the 6 steps one after another.

I had virtual env site package problem and this solved it:

In the case where you are able to import the module when using the CLI interpreter but not in PyCharm, make sure your project interpreter in PyCharm is set to an actual interpreter (eg. /usr/bin/python2.7) and not venv (~/PycharmProject/venv/...)

I had the same problem, I tried all fixes like installing from the project interpreter and installing from python console, nothing worked. What worked was just going to the project folder from the terminal and installing it from there.

How to make pygame on available in an virtualenv? [duplicate]

Pycharm doesn't sync with the pip packages though i have added the path in environment variable.
The following elements will clear the topic:
already installed sklearn package:
pycharm can't find that package:
environment variable:

The thing is that pycharm creates all of your projects inside a virtual environment. So the packages that you installed outside the virtual environment(global site packages) does not get inherited in to your project. There is a simple solution for that. When you create a pycharm project, make sure to check the "inherit global-site packages" checkbox as shown here.Then you'll be able to import all the packages to your virtual environment, provided they have been installed in your computer.
Alternatively you can install all the packages separately using "pip install" in the pycharm terminal. If the package has been installed outside the virtual environment, pip will use cached files instead of downloading the package again.
Or you can install the packages using Settings -> Project -> Project Interpreter as the other answers suggests.

In PyCharm, go to File / Default Settings / Project Interpreter
On that page there is a plus in the bottom left, whatever modules you have installed through pip you may need to manually install there. Or you can change your project interpreter to make sure you are using the correct interpreter with all your installed modules.

Seems like the interpreter selected isn't where you think it is. If you're using a different interpreter than the system's default, it won't load the modules. To add the modules in PyCharm, go to your Settings, Project Interpreter, the Add Button, and install it with PyCharm's integrated package management.

If you did not "inherit global-site packages" upon creating the project, check in the project tree under External Libaries, if the folder is marked in red. I.e. if you do not use the systems default interpreter , Lib/site-packages could be marked in red.
To add those libraries afterwards, go to: File-Project(your project)\Project Structure,
select +Add Content Root, browse to site-packages (or the respective folder you want to add), and add it. After clicking OK the folder will not be marked red any longer. (tested in PyCharm 2020.3)

Add directory to Python path in PyCharm?

I want to be able to use the paraview.simple library in PyCharm. I already have paraview installed in my computer. This package cannot be installed with pip and there are no .whl files as far as I can tell. The website docs recommend that the directory containing all the python files be added to PYTHONPATH.
How do I add the relevant folder in PYTHONPATH on my PyCharm session, and keep it there by default, such that when I close out and reopen the paraview.simple library is still available?

You can add custom paths this way.
Go to File->Settings->project Interpreter
In the Project-Interpreter field, click the down facing arrow and select "show All"
In that Menu, highlight your interpreter and then in the right menu, select the button "Show paths for the selected interpreter" (this is the last button)
click the plus symbol to add your path

Adding interpreter paths in PyCharm:
Project Settings/Project Interpreter: select "settings" icon
Project Interpreters: select "tree" icon
Interpreter Paths: select "plus" icon

In PyCharm version 2020.3.1 use the following workflow instead (see official docs):
Ctrl+Alt+S - open Settings.
File|Settings|Project|Project Structure...
You will see project folder structure. Mark subfolders as Sources or Excluded

Use anaconda with Pycharm
To install paraview with anaconda run the following command: conda install -c conda-forge paraview
If conda command is not recognized then register the Anaconda path to environment variable
Now open pycharm and give the configuration path as the Anaconda path
File -> Settings -> Project Interpreter
In Project Interpreter give similar path : "C:\Users\username\Anaconda3\python.exe"

For me this solved it: mapping the local path to the remote inside the Pycharm run configurations settings.
Edit Configurations > Path Mappings >
Local path = /<Users/me/pycharm etc.../project root>
remote path = /
eg.
