What possibilities exist to build an installer for a windows application on Linux (install target=windows, build environment=Linux) This way, the system will use python3 for running python executables. Tip: For scripts, instead of using a shebang like: #!/usr/bin/env python If you launch interpreters more often (I do), you can always create more aliases to add as well, i.e.: alias 2='python2' If you want to invoke the "original" python (that refers to python2) on occasion, you can use command python, which will leaving the alias untouched, and works in all shells. With this, python command now invokes python3. This way, your alias will work across shells. In your ~/.profile, and then source ~/.profile in your ~/.bash_profile and/or your ~/.zsh_profile with a line like: &. However, you can alias the commands in most shells, Since the default shells in macOS (bash in 10.14 and below zsh in 10.15) share a similar syntax. Where's 3.1?Ĭhanging the default python executable's version system-wide could break some applications that depend on python2. So I went to "/System/Library/Frameworks/amework/Versions/" and discovered that the only sub-folders are "2.3" and "2.5". Obviously this should be version 3.1 instead. So I went to "/usr/bin/" and discovered that "pythonw" was an alias pointing to "/System/Library/Frameworks/amework/Versions/2.5/bin/pythonw2.5". I opened "PythonLauncher" and found that the interpreter for "Python Script" is "/usr/bin/pythonw". So now I tried to figure out why the "PythonLauncher" from "/Applications/Python 3.1" is using Python 2.5.1. (I'm sure of this, I wrote a program to "print(sys.version)".) Now I double-clicked my program to run it, but it was run by Python 2.5.1 instead of Python 3.1. Under "Open With" I selected "PythonLauncher" from "/Applications/Python 3.1". Next I selected the python script I wrote and selected "File", "Get Info" in the menu bar. I went to "/Applications/Python 3.1" and double-clicked "Update Shell mand". I proceeded with the install wizard, and I made sure to check the box to install "Shell profile updater" during the wizard. I opened the file, then opened "Python.mpkg". I downloaded Python 3.1.2 from the Python download page ( this file). Here's exactly what what I did and why I think this is the problem. I think the problem is that the Python 3.1 framework is not being installed. I wrote a Python 3.1 script that my Mac-using friend would like to run, but we can't get Python 3.1 to work right on his Mac.
