OsX Python 3.5 Bad Interpreter：没有这样的文件或目录

Question

I am trying to run the following code from the terminal window. I am following the tutorial found on this website https://automatetheboringstuff.com/chapter6/ . The name of my file is "pw.py" I ran chmod +x pw.py to make it executable from the terminal window. However, when I run ./pw.py I get an error saying "-bash: ./pw.py: python: bad interpreter: No such file or directory". Any Idea what I missed? Thanks for the help!

#! /usr/bin/python
# pw.py - An insecure password locker program.

PASSWORDS = {'email' : 'F7minlBDDuvMJuxESSKHFhTxFtjVB6' ,
             'blog' : 'VmALvQyKAxiVH5G8v01if1MLZF3sdt' ,
             'luggage' : '12345'}
import sys, pyperclip
if len(sys.argv) < 2:
    print('Usage: python pw.py[account] - copy account password')
    sys.exit()

account = sys.argv[1]    # first cammand line arg is the account name

if account in PASSWORDS:
    pyperclip.copy(PASSWORDS[account])
    print('Password for ' + account + ' copied to clipboard.')
else:
    print('There is no account named ' + account)

Answer 1

I figured out my problem. I was not executing it in the terminal correctly. I was entering './pw.py' when I needed to enter 'python pw.py' in order for it to run the script. Thanks for the help.

What you have done looks correct from a python perspective. the #! is called a shebang / shabang and it informs the OS what interpreter to call in order to execute this script.

So I would guess that Python is installed in a different location then what has been supplied. Remember when this is called the full path needs to be supplied. Try running which python to get the location of the interpreter and place that at line 1

I started getting this error when running pip python command, this started happening after a system-wide change in $HOME path, which apparently broke some stuff like pip (the old $HOME path seems hardcoded somewhere in the python installation).

I fixed it by re-installing pip (following this ):

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && python get-pip.py
