TagUI: /usr/bin/env: ‘python’: No such file or directory - update scripts to python3

Personally, if a newb to GNU/Linux was doing this, perhaps it might be better to be able to modify the TagUI codebase depending on Python ver 2 /3,rather than editing a system wide ENV like ‘Python’.

I’ll hack up a BASH/DASH script that will detect the OS.Python.ver and modify those Shebang strings. Might take a few days 😎

@kensoh @pp082 @ghost It really helps me a lot!! Because in the later version of OS(It is macOS 13.3.1 (a) now), I find it hard to create a symbolic link for python from python3 after the upgrade of the system protection(the SIP and when trying to edit the permission of root file another error occurs like: “/data: Read-only file system”) and I suffer it for a whole day!!! THANKS!!

@ghost, @kensoh

Thank you very much I had the same problem with my Mac M1 pro.

Python 3.9 is preinstalled. Making the change from python to python3 solved it.

Execute TagUI

$ tagui /home/qih/tagui/flows/samples/1_google.tag
/usr/bin/env: ‘python’: No such file or directory

Reoccurence of original issue:

Modify ~/tagui/src/tagui

# Python (2)
# python -u tagui_py/tagui_py.py >> tagui_py/tagui_py.log 2>&1 &
# Python (3)
python3 -u tagui_py/tagui_py.py >> tagui_py/tagui_py.log 2>&1 &

Execute TagUI

$ tagui /home/qih/tagui/flows/samples/1_google.tag
/usr/bin/env: ‘python’: No such file or directory

Logic dictates that there must be other references to ‘python’ within the codebase that are getting called and causing this error, therefore must find these instances.

Summary:

If your GNU/Linux system uses Python 3, you must modify all instances of ‘python’ to ‘python3’, after that, it works as per design.
