Install Python and Thonny separately
If there is no Thonny+Python bundle for your operating system or you can't or don't want to use it, you can first install Python (or use your existing Python) and then install Thonny in the context of this Python installation.
- Install Python 3.5 or later (or choose an existing installation).
- Install Thonny package with pip using your operating system command line.
- Run Thonny package.
Mac OS X
If you don't have Python 3.6 or later installed, then go to https://www.python.org/downloads/mac-osx/ and install latest Python 3.7 from there. (NB! Thonny 3.0 requires Python which is linked to Tk 8.6. Python 3.7 provided at www.python.org is suitable for this.)
For installing Thonny as package, you need to go to system command line and execute something like pip install thonny, but you need to make sure command pip is related to correct Python installation.
For opening system command line:
- open Finder
- from the menu choose Go => Utilities
- open "Terminal"
Assuming you are using official Python 3.7 distribution, paste following into Terminal and press ENTER:
/Library/Frameworks/Python.framework/Versions/3.7/bin/pip3.7 install thonny
You should see something like this:
Now you can run Thonny with following command:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 -m thonny
