I am running a python script from the IDE and it works well, however when calling it from the git-bash terminal the following errors showed.
./main.py: line 2: import: command not found
./main.py: line 3: import: command not found
./main.py: line 5: syntax error near unexpected token `'I am in main 1''
./main.py: line 5: `print('I am in main 1')'
In git-bash I run the chmod u+x main.py and chmod +x main.py lines, but it still does not work.
I am using VScode as my IDE with python3.7.9 as the interpreter, I am calling the script from the direction where it is placed in the terminal, and the script that I am testing is the following:
#!/bin/bash
import os
import sys
print('I am in main 1')
I have changed the first line for #!/bin/bash/python and #!/bin/bash/env python3... didn't work. I would appreciate it if someone could tell me what I miss or what I am doing wrong. I am new in git or using the terminal, any tip would be appreciated.
Thanks in advance.
Not sure if you made the error in typing this question or if it's also like this in your script, but you should have #!/usr/bin/python3 or #!/bin/python3 for your system to know to execute it as a python script.
As it stands, your system is trying to execute it as a shell script with bash, which would explain why the import statements aren't being recognized.

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?
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
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.
I need some advice with a Python script. I'm still new and learned it by myself. I found the script on Google. After I retype it, it doesn't print the result in the console. How can the result of the script be shown in the console? Details as below:
C:\Python27>test1.py af8978b1797b72acfff9595a5a2a373ec3d9106d
C:\Python27>
After I press enter, nothing happens. Should the result be shown or not?
Here's the code that I retyped:
#!/usr/bin/python
#coding: ascii
import requests
import sys
import re
url = 'http://hashtoolkit.com/reverse-hash?hash='
try:
hash = sys.argv[1]
except:
print ("usage: python "+sys.argv[0]+" hash")
sys.exit()
http = request.get(url+hash)
content = http.content
cracked = re.findall("<span title=\*decrypted (md5|sha1|sha384|sha512) hash\*>(.*)</span>", content) # expression regular
print ("\n\tAlgoritmo: "+cracked[0][0])
print ("\tPassword Cracked: "+cracked[0][1])
The first line in your script is called a Shebang line.
A Shebang line tells the script to run the Python interpreter from that location.
The shebang line you provided is a Linux system path, but it looks from the path you are executing Python from, that you are running on Windows.
You can do one of two things here to fix that:
Remove the Shebange Line.
Remove the first line from your script.
Execute the script using python test1.py COMMAND_LINE_ARGUMENTS
Modify Your Shebang line.
Change the first line of your script from !/usr/bin/python to
#!python (This is assuming that python is in your systems PATH variable.)`
Execute the script using test1.py COMMAND_LINE_ARGUMENTS
Also, you are trying to import the requests module that is not installed in the standard library.
If you haven't installed this yet, you can do so by going to your Python install directory and go to the scripts folder.
Hold shift and right click and go Open command window here
Type pip install requests and hit enter.
After that you should be good to go, execute the script by navigating to it and type test.py COMMAND_LINE_ARGUMENT
If a Python script doesn't have the shebang line:
python test.py COMMAND_LINE_ARGUMENT
you need to run your script using python. try:
C:\Python27>python test1.py af8978b1797b72acfff9595a5a2a373ec3d9106d
I have a self-installed python in my user directory in a corporate UNIX SUSE computer (no sudo privilege):
which python
<user>/bin/python/Python-3.6.1/python
I have an executable (chmod 777) sample.py file with this line at the top of the file:
#!<user>/bin/python/Python-3.6.1/python
I can execute the file like this:
python sample.py
But when I run it by itself I get an error:
/full/path/sample.py
/full/path/sample.py: Command not found
I have no idea why it's not working. I'm discombobulated as what might be going wrong since the file is executable, the python path is correct, and the file executes if I put a python command in the front. What am I missing?
EDIT:
I tried putting this on top of the file:
#!/usr/bin/env python
Now, I get this error:
: No such file or directory
I tried this to make sure my env is correct
which env
/usr/bin/env
EDIT2:
Yes, I can run the script fine using the shebang command like this:
<user>/bin/python/Python-3.6.1/python /full/path/sample.py
Your file has DOS line endings (CR+LF). It works if you run python sample.py but doesn't work if you run ./sample.py. Recode the file so it has Unix line endings (pure LF at the end of every line).
Try using #!/usr/bin/env python as described in this post. Let the OS do the work.
I was about to test the ftpmirror builtin script (python322, winXP 32bits) from the cmd windows default shell and get this :
File "C:\Program Files\python322\Tools\Scripts\ftpmirror.py", line 161
print('Skip pattern', repr(pat), end=' ')
^
SyntaxError: invalid syntax
I tested the print() line directly in the python shell, trough cmd, and with idle (and in blender also) : this work obsiously.
I reproduce the error with a coucou.py file like this :
#! /usr/bin/env python3
pat = 'toto'
print("Skip pattern", repr(pat), end=" ")
when directly called from a cmd prompt :
C:\Program Files\python322\Tools\Scripts>coucou.py
same error than with ftpmirror
but :
C:\Program Files\python322\Tools\Scripts>python coucou.py
is ok
and my environment is ok I can execute py scripts directly from the windows ui by double-clicking a .py file, and I got working scripts working fine when called from .bat
I don't get it, it looks specific to the print() end argument, what did I not read yet about the way to execute python3 from the windows cmd shell ?
thanks,
Jerome
Try checking if you are running the same python interpreter when you double click or you run python from the command-line.
Save this in a .py file with this content and try running it with both methods:
import sys
print sys.version_info
I bet you are using different interpreters in each case.
So, I created a simple python module, test.py
import commands
def main():
cmd = 'ls -l'
(status, output) = commands.getstatusoutput(cmd)
print status, output
if __name__ == '__main__':
main()
When I ran it using "Python test.py", I got the result that I expected. But when I ran it as an executable (yes, it has the 'x' permission), the program didn't respond at all and I had to Ctrl+C to quit it. Why is that? Shouldn't both ways give the same result?
Add a hash-bang line to the top:
#!/usr/bin/env python
import commands
...
This tells your system what interpreter to use to execute the script. Without it it doesn't know if it's a shell script, Perl script, Python script, what.
You need the hashbang to be the first line of your script, referencing the path of the Python interpreter. Otherwise, all the OS knows is that you're trying to execute a script, and it has no idea how to go about doing that.
