I need to run an application written in python. When I try to load it from terminal I get this error:
File "/usr/local/bin/soar", line 3, in <module>
import form.main
File "/usr/local/lib/python2.6/site-packages/form/main.py", line 14, in <module>

File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 39, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter
I installed python 2.6.6 from the source files. I am really confused!!
How should I install tkinter?
I am running Xubuntu 13.10. You can see the different versions of python already installed in the below:
How can I remove python2.6.6? I tried to remove all files and folders related to python2.6. Now when I run python, it still loads python 2.6.6 I really have no idea what to do!! I tried to follow the instructions here and here to uninstall it but it did not work, that's why I deleted all the files and folders manually.
Type the following in your terminal:
sudo apt-get install python-tk
Install python3-tk package if you need Tkinter functionality in the 3rd version of python.

The default Python version for MSYS2 seems to be 3.8. I need to use 3.7 at the moment because I have to use PyInstaller and it is not currently compatible with 3.8 in MSYS2. I can download the earlier version of Python from http://repo.msys2.org/ and install it using pacman. With a fresh install of MSYS2 I run the following commands:
pacman -S glib2-devel
pacman -U python-3.7.4-1-x86_64.pkg.tar.xz
pacman -S python-pip
pacman -S python-setuptools
If I try to run a python script I am met with an error:
File "setup.py", line 15, in <module>
from setuptools import setup
ModuleNotFoundError: No module named 'setuptools'
This is due to the fact that everything installed after Python is actually installing in the default Python 3.8 location rather than 3.7:
C:\msys64\usr\lib\python3.8\site-packages
If I copy and paste the contents of site-packages into Python 3.7 and then try running a script I get the error:
File "setup.py", line 15, in <module>
from setuptools import setup
File "/usr/lib/python3.7/site-packages/setuptools/__init__.py", line 19, in <module>
from setuptools.dist import Distribution

import ctypes
File "/usr/lib/python3.7/ctypes/__init__.py", line 7, in <module>
from _ctypes import Union, Structure, Array
ImportError: No such file or directory
Which is supposed to be resolved via libffi, which was installed prior to Python, but likely does not go to a location that 3.7 can recognize?
Is there a way to set a specific version of Python as the default in MSYS2? Perhaps a path that can be set in the .bashrc file? I tried to set PYTHONPATH in there to Python 3.7 but it didn't make a difference as to where the packages ended up being installed to.
Go to the following URL...
https://repo.msys2.org/msys/x86_64/
Look for the version of the package you need and download it. Use
pacman -U pkgname
To install it...
The reason I know this is because gcc11 on MSYS is non-functional... it produces programs which crash and say
"During startup your program exited with code..." mentioned here:
During startup program exited with code 0xc0000139
The only workaround is to downgrade to the previous compiler which does work or use clang, which was not an option for me.
Trying to use an old version of Python is probably possible, but I think it will be very difficult. You would need to make sure all the other installed packages are compatible.
I am using PyInstaller with Python 3.8 in MSYS2 without issues. I would recommend trying to work through any issues with that, instead of trying to use older versions of packages.
I am an absolute newbie. I'm trying to make Python GUI for my school project so I decided to use Tkinter. When I try to import Tkinter it throws this message:
>>> import tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/tkinter/__init__.py", line 36, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
I tried to find a solution online but I couldn't figure it out (mostly didn't understand it).
I read about some problem with directory in setup.py but I don't understand how to fix it. I have tkinter folder in my python3.7 folder.
I don't really understand these steps that I found:
If it fails with "No module named _tkinter", your Python configuration needs to be modified to include this module (which is an extension module implemented in C). Do not edit Modules/Setup (it is out of date). You may have to install Tcl and Tk (when using RPM, install the -devel RPMs as well) and/or edit the setup.py script to point to the right locations where Tcl/Tk is installed. If you install Tcl/Tk in the default locations, simply rerunning "make" should build the _tkinter extension.
I'm using Mac OS and use Visual Studio Code.
To check your python version, run this on terminal:
$ python --version
Check what python your machine is using. Run:
$ which python
If it's using python from Homebrew, it's probably using Python 2. If you installed python 3 manually, just install tKinter manually.
$ brew install python-tk
To run python 2 manually, run on terminal:
$ python <FILENAME>
If python 3, run:
$ python3 <FILENAME>

In summary, you have to reinstall python for your computer bit system.
And below code strategy is also helpful to you.
try:
from Tkinter import * # for Python2
except ImportError:
from tkinter import * # for Python3
As some brief background information: I was origianlly trying to use Miniconda (with conda) to install dependencies that I need for my project on my Raspberry Pi. After trying to use Conda to install the SimpleAudio package, I got an error saying that it did not exist, therefore I proceeded to install this through Pip. Pip found the correct package although I get the following error message:
pi#raspberrypi:~ $ pip install simpleaudio

It seems I need to update Python, although when I print the verion on Spyder IDE, it says I am already using 3.7.
Have I caused some sort of mismatch between what version my IDE is using and what the default process the terminal uses to look up the version? I noticed that it is looking for the Python version under Miniconda. If I can update If so is there a fix for this?
Please as me for more information if required (I am fairly new to stack overflow).
UPDATE:
I have been able to install the updated version of Python to 3.6 using the following instructions:
https://stackoverflow.com/a/56852714/12361146
This generally solves the scope of this question in terms of how I update Python, but I am still confused as to why Spyder IDE uses a more up-to-date version of Python whereas the terminal shows otherwise.
To answer the question of why Spyder reports a more up-to-date version of Python, here's the reason. The default versions of Python that are installed with Raspbian are 2.7 and 3.5, located in the /usr/bin/ directory. When you install Spyder, however (either independently, or more commonly, using conda), it includes its own installation of Python, which it is configured to use in the IDE, and which is located in a different directory. Hence when you compare the versions, first by entering python3 --version on the command line, and then print(sys.executable) from the Spyder IDE, they're different.
Now the issue with using pip alongside conda for updating the Spyder installation of Python is that it has the potential to mess it up quite badly, so avoid that unless you really know what you're doing. From code you posted above, you have avoided that, though, since that will have impacted the default Raspbian installation of Python, not the Spyder one. Upgrading the latter version should be done using Conda, not pip.
Hopefully you're now all up and running.
You can install newer versions of python using the package manager apt or apt-get.
Start by getting up-to-date package definitions.
$ sudo apt-get update
Then you can show details about the python3 package.
$ apt-cache show python3
When I run that now I get "Version: 3.7.3-1".
To install the python3 package and all its dependencies.
$ sudo apt-get install python3
You will still need to type python3 and pip3 when you run the commands because you are not replacing the built-in python 2.7.
Try these commands to see what you get
$ python --version
$ python3 --version
If you want to change the default python to python3 then have a look at this answer How to change the default python version in Raspberry Pi
When I import tinker in python 3.7.3 on Ubuntu 18.04:
>>> import tkinter
I got:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.7/tkinter/__init__.py", line 36, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
Then I install tk using both of the following:
sudo apt-get install python3-tk
It didn't work.
I also did all the things in Tkinter module not found on Ubuntu, still didn't work.
I noticed that when I do:
sudo apt-get install python3.7-tk
It says:
Note, selecting 'python3-tk' instead of 'python3.7-tk'
python3-tk is already the newest version (3.6.9-1~18.04).
Is tk automatically installed under python 3.6.9? How can I fix this?
I also saw a solution from https://wiki.python.org/moin/TkInter:
If it fails with "No module named _tkinter", your Python configuration needs to be modified to include this module (which is an extension module implemented in C). Do not edit Modules/Setup (it is out of date). You may have to install Tcl and Tk (when using RPM, install the -devel RPMs as well) and/or edit the setup.py script to point to the right locations where Tcl/Tk is installed. If you install Tcl/Tk in the default locations, simply rerunning "make" should build the _tkinter extension.
Could someone explain to do how to do the steps mentioned in this paragraph?
OK. I think the problem is that the newest version of tkinter for Ubuntu 18.04 is "python3-tk_3.6.9-1~18.04_i386.deb". Now I found that tk for python3.7.3 is available for other systems(e.g. python3-tk_3.7.3-1_amd64.deb). Can I download and use these ones on my system?
acw1668: Thanks this helped me a lot. I'm using Python 3.8. Using your method was able find where tkinter for Python 3.8 was install (/usr/lib/python3.8/). So i copied the files to (/usr/local/lib/python3.8/) which is where Python is installed on my computer. Now it'e working.
I do not understand how Intellij "finds" the installed python modules.
Here is an example: I have installed the python mysqldev
sudo apt-get install python-mysqldb
It is working on command line python. But IJ does not see it
File "/shared/git2/etl/appminer/hive/DB.py", line 7, in <module>
import MySQLdb
ImportError: No module named MySQLdb
So how to make IJ aware of the installed python libs?
thanks
