Python: Can not run python file without `python` command on Mac?

Question

On Terminal,

>> which python
/Users/Chois/.pyenv/shims/python

aa.py

# !/Users/Chois/.pyenv/shims python
print("a")

On Terminal,

chmod 755 aa.py

And execute it,

./aa.py

It occured errors

./aa.py: line 3: syntax error near unexpected token `"a"'
./aa.py: line 3: `print("a")'

What's wrong with it?

• Synook: You're missing a / between shims and python in the hashbang (having a space instead), and have an erroneous space between # and !

Answer 1

Rather than using full path for the python binary, your shebang line could use the env instruction. Then, your shebang line will end up being something like this:

#!/usr/bin/env python

Answer 2

The shebang line is blatantly wrong... You shouldn't have a space between the hash and the bang:

#!/Users/Chois/.pyenv/shims/python

There's also a missing slash that I filled it for you.
