I think the short version of this question is: How do I get a virtualenv running Python 3.5 to point to the correct version of ActiveTcl on a Mac?
Here's the longer version:
I'm trying to run this Korg Electribe sample editor project on a Mac. The author has only tested it on Windows, and based on the screenshots, it appears to work. I've been able to run the basic python script fine, but as I mention in an issue that I've opened, the full window turns black after loading a file.
After doing some research, I've found that there is a known issue with Aqua Cocoa Tk, and python.org has provided some instrunctions about how to fix tkinter for Mac OS 10.9 and up. I've attempted installing both of the suggested ActiveTcl (8.5.18.0) as well as the newer 8.6.x.x version without success.
I'm pretty sure this is a different issue than Tkinter not working mac osx el capitan, since the script does run, and the window is drawn properly on launch. It's only after I've attempted to load a .all file (there's a sample file in the Github issue) that the screen goes black.
After some more research, I've found this question that seems related, but is specific to Windows: TKinter in a Virtualenv
I'm under the impression that if I can figure out what to set TCL_LIBRARY to, that I'll be able to make some head-way, but I can't seem to find that information for the packages listed on python.org.
Somewhat related, it would also seem to be helpful if I could figure out which version of Tcl/Tk that tkinter is pointing to from within Python, so if anyone could help with that as well, I'd greatly appreciate it.
Thanks!
I succeeded in using tkinter in a python3 virtualenv on OSX 10.13 by :
installing the official OSX Python 3 from https://www.python.org/
installing activeTcl from https://www.activestate.com/activetcl
creating a new virtualenv
mkvirtualenv myenv --python=python3
locating the tkinter location in the Python3 directory. For me it was here :
/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter
creating a symbolic link in the virtualenv library pointing to the tkinter location
cd ~/.virtualenvs/myenv/lib/python3.6
ln -s /usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter tkinter

I'm learning Tkinter right now and trying to work through my first issue, but finding Google hasn't been helpful.
I'm running this code on Mac OS X 10.15.1 (Catalina)
I'm using Python 3.7 and my code looks like so (lots of boilerplate per PEP8 standards):
"""
Experiments in tkinter
"""
import tkinter as tk
def main():
"""
Main entrypoint
"""
tk._test()
if __name__ == "__main__":
main()
This outputs the following warning to the console:
DEPRECATION WARNING: The system version of Tk is deprecated and may be removed in a future release. Please don't rely on it. Set TK_SILENCE_DEPRECATION=1 to suppress this warning.
It also displays a window with completely blank buttons:
From my understanding these buttons should say "Click Me" and "Quit".
Also when I click on the top button it flashes black for a second like so:
After which the button is wider than before:
I assume the Tk version error may be related to the output behavior. However I can't seem to find a way to update Tk. What should I do here?
Update
After seeing #ShayneLoyd's answer (suggesting I needed an updated version of Python with an updated version of Tk) I began looking around some more and found this post on the Apple Discussion Boards which suggests you can use homebrew to install a version of Python which link's homebrew's own installed version of Tk. I tried this and it failed, so I Google'd the issue and found this StackOverflow post which seemed to suggest I can install
ActiveTcl and it will work.
I installed ActiveTcl from ActiveState and went back to my project. At first, I ran it like so:
$> cd ~/Source/experiments/python/tkinter
$> ./test.py
This actually worked! I could read the buttons and it behaved like it should. Then I realized I was not using pipenv, so I did a quick test:
$> pipenv run ./test.py
Now I was back to the failure state. I updated my script to display the Tcl and Tk version and sure enough when I used pipenv it was loading Tcl/Tk 8.5.9 but when I didn't use pipenv it was loading 8.6.9
So how do I fix pipenv now?
For anyone who's having the same issue and cannot switch Python version, you can easily bypass the "not showing text on buttons" problem by changing MacOs theme. System Preferences>General>Light Mode.
You should have in mind that you may encounter other problems.
After a few hours messing with it I figured it out!
The Pipfile contained a reference to Python version 3.7
Therefore pipenv install was searching my machine for any 3.7 version of Python installed. The version it found was Homebrew's, which has Tk 8.5.9 statically linked.
By updating the Pipfile to require Python 3.8 my machine started pulling my system Python, which uses the dynamically linked Tk, which I had successfully updated to 8.6.9
I've been struggling with getting wxPython work - I'm running a Mac, OSX 10.11.6 El Captain, so the pip install runs into /src/osx/cocoa/mediactrl.mm:52:10: fatal error: 'QTKit/QTKit.h' file not found with the new XCode, and some changes there, and won't compile. So I found an installer, that at least gets it done.
But then wx runs (I only tried to import it in fact) in my conda python 2.7.12.
My goal is to be able to play around with TensorKart and since my default python is conda, when attempting to run the repo, it tells me the usual:
This program needs access to the screen.
Please run with a Framework build of python, and only when you are
logged in on the main display of your Mac.
I found how George Reilly explains here what to do, but I cannot find the wxredirect.pth and don't know what to do with the bash script. I only have wx.pth within the conda site-packages.
So is it somehow possible to get the wxPython for my Framework 2.7.10 with the .dmg installer? After 6 hours of struggle it seems like the easiest way.
I tried:
copy conda site-packages having to do with wxPython into site-packages within a virtualenv created form the Framework Python as it was in the original G. Reilly's post which no longer works.
create alias in .bash_profile that python is the Framework version but it didn't help.
Thanks a lot!
Being a complete begginer in python, I decided to install the python interpreter 3.4.4, and also PyDev plugin for eclipse IDE. I am also using windows 10.
I have encountered a problem regarding certain imports, namely : from PIL import Image, ImageTk, which is apparently an unresolved import.
I have looked at certain questions which were similar to my situation, but most of them gave a solution like installing packaged from the linux apt-get. Here are some topics I visited :
Uninstalling and reinstalling Pillow and pip,
Installing pillow-imaging-tk on Ubuntu,
This topic which left me very confused,
This one seemed helpful, but is on Unix OS again
So please, could someone explain to me why I am seeing this error, and how could I correct it if I absolutely want to use Eclipse, Pydev, windows 10 and Python 3.
Found the solution, here's what I did:
Set the PYTHONPATH like it is shown in this article, make sure python.exe is accessible via cmd,
Via cmd, type pip install pillow. Alternatively, you can enter the same command from Windows+R,
(Not sure if relevant step) Via eclipse, Windows->Preferences->PyDev->PythonInterpreterremove your interpreter to re-add it,
Restart eclipse.
For Python import problems in PyDev, the project web site has a page on interpreter configuration that is a good place to start. I recently had a similar problem that I solved by adding a module to the forced builtins tab.
I am running a MacBook Pro with 8gb of memory and a 2.5GHz processor. I run OS X Mavericks, but this problem has happened on other operating systems as well. when I try to open the editor, or even open a python file, this happens:
This has been a problem since I got into python. I have tried as many versions as I can, and the same screen pops up. Please help
I recently also upgraded a friends iMac to OS X 10.9 Mavericks and her Python to 2.7.6. If you mount the python-2.7.6-macosx10.6.dmg disk image there's a text file named ReadMe.txt. If you ahem, actually read it, right near the beginning it says:

Update your version of Tcl/Tk to use IDLE or other Tk applications
To use IDLE or other programs that use the Tkinter graphical user
interface toolkit, you may need to install a newer third-party version
of the Tcl/Tk frameworks. Visit
http://www.python.org/download/mac/tcltk/ for current information
about supported and recommended versions of Tcl/Tk for this version of
Python and of Mac OS X.
Here's what http://www.python.org/download/mac/tcltk currently looks like (my highlighting):
To summarize: You need to download and install ActiveTcl 8.5.15.1 (which is mislabeled ActiveTcl 8.5.15.0) from ActiveState's webpage. After doing that you should be able to run IDLE:
I haven't actually tried to do it yet, but from what I read it sounds like the same process applies to Python 3.3.3 and its IDLE app.
I was having the exact same problem.
I was finally able to install Python (and IDLE) via MacPorts by also installing a package called "pyXX-tkinter" -- where XX is the version, e.g. py34-tkinter for Python 3.4.
I recently attempted to install python 3.2 along with IDLE 3 on my macbook pro. I successfully installed python 3.2 (as in, I can run it from the terminal), but when I attempted to install IDLE 3.2 I must have done something wrong because now both IDLE 2.7 and IDLE 3.2 crash immediately upon opening with the message "Python quit unexpectedly", no matter whether I open it through the terminal or through finder. Does anyone know how to fix this? I have installed the correct ActiveTCL package (and reinstalled) and still nothing. I have attempted to reinstall python 3.2 and IDLE 3 but I am not sure whether I did it correctly. Through a good amount of googling I found some people say that it was most likely a path issue but all of the solutions I found were using Windows so I am not sure how to apply that to my mac.
Try renaming or removing the directory ~/.idlerc which is about the only thing used by Python that would in common to IDLE for 2.7 and 3.2. If that doesn't help, state exactly which Python 3 you installed, what version of OS X, and show the stack traces from the termination report.
UPDATE: Based on the crash report you've supplied, it appears that Tk is crashing during its initialization of menu items:
...
4 Tcl 0x00000001013dfa61 Tcl_Panic + 162
5 Tk 0x000000010151c523 TkpGetColor + 383
6 Tk 0x0000000101529a25 TkpMenuInit + 156
7 Tk 0x00000001014ac254 TkMenuInit + 88
8 Tk 0x000000010152c687 -[TKApplication(TKMenus) _setupMenus] + 53
...
I have not seen any reports of a similar problems when IDLE is used with A/S Tcl/Tk 8.5 on 10.7.3 and I haven't been able to reproduce it myself on 10.7.3. However, the Cocoa Tcl/Tk 8.5 is not the most robust framework out there and it may be susceptible to problems when using languages or input methods other than US or US Extended. Another possibility (more likely) is if you are using some third-party menu enhancement application or preference panel (to add colors to menus perhaps). If those suggestions don't help you to isolate the problem, I suggest you ask on the Tcl Mac mailing list (tcl-mac#lists.sourceforge.net, archived at http://dir.gmane.org/gmane.comp.lang.tcl.mac).
If you are running Mac OS X Lion, it sounds like you are being bitten by the saved-state crash. You need to delete the saved state to make the crash go away:

http://reviews.cnet.com/8301-13727_7-20083707-263/managing-mac-os-x-lions-application-resume-feature/
I had the same issue. I run OSX 10.8.5, Python 3.3.3 and IDLE 3.3.3 and reinstalling Python haven't been a solution.
I solved any problem removing the ~/.idlerc directory. My problem showed for the first time when I tried to change some Preferences (IDLE->Preferences->General->Startup Preferences->At Startup Open Edit Window), so I suppose that's why resetting my Preferences deleting ~/.idlerc folder have been the solution.
I had the same problem where IDLE would crash after I opened it on my MAC
I ended up updating my computer to OS Yosemite.
and the most updated version of python but it still would shut
the reason it started was because I tried to change the preferences for certain keys.
Resetting the preferences fixed it!
I typed mc ~/.idlerc idlerc2
:)
[Solved] I had the same problem here using:
Yosemite 10.10.2
python 3.4.2
The issue was solved downloading and installing the ActiveTcl 8.5.17.0 version from http://www.activestate.com/activetcl/downloads
