exec: does not exist (No such file or directory)

Question

I'm using WSL with docker (with a complex pandoc configuration with latex, python and pandoc-filters) and trying a long command with --filter=filters/the_filter.sh that results in an error:

Error running filter filters/the_filter.sh: ./filters/the_filter.sh: createProcess: runInteractiveProcess: exec: does not exist (No such file or directory)

My filter is a .sh wrapper, mostly to make sure I'm using Python3 (which may not be needed, but I got the hint from here):

#!/bin/sh python3 filters/the_filter.py $@

Googling the error shows lots of GitHub issues, but no definitive explanation on Stack overflow.

It turns out that my .sh file had Windows line endings: \r\n. I assume that the system was trying to find /bin/sh\r but the error message is not explaining it.

Correcting the line-endings using dos2unix filters/the_filter.sh, I was able to get rid of the error.

Here are more details of a related problem.

Hi @Fuhrmanator, did you solve the issue? Not sure, but I think you should accept your own answer.

@Gabriele one must wait two days before accepting one's own answer.

I see, I didn't know :)

When writing a filter with panflute I found that having CRLF line endings in the python filter itself caused this error too.
