需要使用cpanel通过cron作业运行python脚本

Question

I need urgent help in this regard. I am trying to run a Python script via cron job on cPanel. The web hosting server is using cPanel Version 11.30.3 (build 5) . The cron job is set successfully and it is executing the file, but the file failed because of the following error which I recieved on email:

/bin/sh: /home/someuser/public_html/xml_feed/cron_job_wod.py: /usr/bin/python
: bad interpreter: No such file or directory

What I have done so far:

1. I have placed cron_job_wod.py under public_html/xml_feed/cron_job_wod.py with all permission 777 code
2. I have added this #!/usr/bin/python at top of my script
3. I have added appache handler called cgi-script with extensions .cgi .py .pl

...but still the script is not working. How could I get the right path of the Python interpreter? or what is the solution for this problem? Please help!

Note that in the error message, there is a line break after /usr/bin/python and before the : that clarifies the message. This suggests that the operating system is seeking the file not at /usr/bin/python but at /usr/bin/python<newline> .

Most likely, you copied the python file from a Windows system which has a style of linebreaks that /bin/sh is not expecting to see in your script.

You can solve this problem by converting the Windows-style newlines in the python script file with the following command.

dos2unix /home/someuser/public_html/xml_feed/cron_job_wod.py

If dos2unix is not available on your system, here are a list of alternative methods that effect the same change.
