This question already has an answer here:
Cannot figure out, where to change EOF in PyCharm. My scripts, started with:
#!/usr/bin/python
# -*- coding: utf-8 -*-
Outputs something like this, when I try to run it like executable (chmode +x):
-bash: ./main.py: /usr/bin/python^M: bad interpreter: No such file or directory
What to do and how to be?
Set line separator to Unix:
The issue is not EOF but EOL. The shell sees a ^M as well as the end of line and thus tries to find /usr/bin/python^M .
The usual way of getting into this state is to edit the python file with a MSDOS/Windows editor and then run on Unix. The simplest fix is to run dos2unix on the file or edit the file in an editor that explicitly allows saving with Unix end of lines.
You may find the answers here: ./configure : /bin/sh^M : bad interpreter
As a Mac OS X user, I didn't find the command dos2unix. Alternatively, I use vi/vim: :set fileformat=unix and then save the file :wq
If you are using Vim, just enter the following command:
:set fileformat=unix
you may want to try dos2unix <filename>
Install dos2unix: sudo apt-get install dos2unix
and let it do the magic: dos2unix FILENAME
For MacOS you can install it via Homebrew like this:
brew install dos2unix
And next do
dos2unix FILENAME
Similar to Jiangwei Yu's post. On UNIX/Linux, I used vi to edit the Python file. Using vi, you can see the ^M at the end of each line.
Find the following line /usr/bin/python^M
Hit end to get to the end of the line
Hit delete to remove the ^M
To save the file and quit, type in: :wq
This worked for me.
you may try to do this:
sed --in-place 's/^M//g' main.py
[ to type in ^M, press ctrl+v,ctrl+m ]
Just a Question of format beween win and unix:
try command: dos2unix fileName
After it run again, it should work
