Почему, когда я указываю путь к python3 в файле, он все равно обрабатывает через python2?

Я работаю с pyinstaller-3.2, который интерпретирует фалы через python2.7, а мне нужен python3. Указываю путь к python3

#!/usr/bin/env python3

Даже

#!/usr/bin/python3

Но, при сборке, он просто не читает указатель пути к python3

./pyinstaller.py --onefile main.py

А выдает ошибку: по понятным причинам

  File "/home/pepe/PyInstaller-3.2/main.py", line 2
    print('Hello', end=' ')
                      ^
SyntaxError: invalid syntax

файла main.py:

#!/usr/bin/env python3
print('Hello', end=' ')

с использованием интерпретатора python3

python3 -m PyInstaller *args

выдает ошибку
