I get a "Pandoc executable is not executable" error, but Pandoc is working fine #5

I get a "Pandoc executable is not executable" error, but Pandoc is working fine. Not sure what to do from here.

outofcontrol commented 5 years ago

What does this show:

ls -la `which pandoc`
paulzim commented 5 years ago

ls: cannot access 'which pandoc': No such file or directory

Maybe I need to process in another directory?

outofcontrol commented 5 years ago

Be sure to use back tic's around which pandoc, not single quotes. Equally you can do to steps:

which pandoc

take the output of that and do:

ls -la /usr/local/bin/pandoc

Changing /usr/local/bin/pandoc for the path you got.

Ah, I see where the problem is... it's choking on the program location:

which pandoc
/c/Program Files/Pandoc/pandoc

pzimmerm@PZIMMERM-M6P2G MINGW64 ~/Documents/GitHub/mediawiki-to-gfm (master)
$ ls -la /c/Program Files/Pandoc/pandoc
ls: cannot access '/c/Program': No such file or directory
ls: cannot access 'Files/Pandoc/pandoc': No such file or directory

pzimmerm@PZIMMERM-M6P2G MINGW64 ~/Documents/GitHub/mediawiki-to-gfm (master)
$ ls -la `which pandoc`
ls: cannot access '/c/Program': No such file or directory
ls: cannot access 'Files/Pandoc/pandoc': No such file or directory

I tried to reinstall Pandoc but it's not letting me change the location

Any suggestions would be appreciated!

paulzim commented 5 years ago

OK, I fixed the Program Files issue... I was able to reinstall in another location, but I'm still getting the same error... not sure why now...

pzimmerm@PZIMMERM-M6P2G MINGW64 ~/Documents/GitHub/mediawiki-to-gfm (master)
$ ./convert.php --filename=C:\Users\pzimmerm\Documents\Pandoc\DocWiki-20190103183530 --output=C:\Users\pzimmerm\Documents\Pandoc\Converted
Pandoc executable is not executable

Not on Windows here so a bit tough to figure out. If we look at the Pandoc code, this is where that error comes from:

if ( ! is_executable($this->executable)) {
    throw new PandocException('Pandoc executable is not executable');
}

Can PHP execute Pandoc in the location you have it store? I've seen a reference somewhere that the folder Pandoc is in must have proper permissions for PHP to be able to run Pandoc. Though I am unsure of those permissions for Windows. Not much, but hopefully this will help you find a solution.

OK, thanks... I'm having a Mac person on my team try it out. I really appreciate all your help... and I hope this works, it would save a bunch of time!!

outofcontrol commented 5 years ago

If you figure out, please post your solution, in case it is helpful to others.

paulzim commented 5 years ago

Will do!

We got it to work on a Mac with a couple of issues:

A couple of notes on running this on Mac: I had to run php composer update --no-dev rather than composer update --no-dev. I had to upgrade my pandoc install from 1.19.2.1 to 2.5 to get the PHP script to run.
