Chromedriver is in the path, yet reports not in the path!

[zenny]

Hi,

This fails to run with "chromedriver not in the path"!

~/Downloads/gitrepos/antincleon-edx-dl ]$ which chromedriver
./bin/chromedriver

$ echo $PATH
PATH=./bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:./bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/home/zenny/gitrepos/antincleon-edx-dl/bin

$ ls -la ./bin/chromedriver
-rwxr-xr-x 1 zenny zenny 12M Jul 27 03:27 ./bin/chromedriver

All requirements (binary and path and executablity) are satisfied, yer running the script errors out as if chromedriver is not in the path:

Even install chromium package to satisfy Chrome binary, it opens up the chromium and does just create a folder without any content!

Hmmmm???
