Why is Raspberry pi ignoring #!/usr/bin/env python in a Python script?

Question

Python

Or rather, he writes that an unknown team. Tried
#!/usr/bin/env python
AND
#!/usr/bin/env python3
AND
#!/usr/bin/python
AND
#!/usr/bin/python3
And if I run python3 script.py runs fine.

Answer 1

and the utility itself is /usr/bin/env on this path? Are the permissions correct?

Answer 2

Perhaps your python is in a different directory?
This is how you find out which address is substituted when executing the command python3 script.py:
Look at the contents of the folder from which the interpreter cannot be launched (and check the file permissions, if any):
ls -la /usr/bin

Answer 3

Try to run like this, in the directory with the script:./script.py
