[SOLVED] Cronjob - Unable to find Mozilla geckodriver

Issue

I have geckodriver installed in the usr/local/bin directory and exported to the $PATH variable.

export PATH=$PATH:~/usr/local/bin/geckodriver

You can see usr/local/bin is in my $PATH

root/.rbenv/plugins/ruby-build/bin:/root/.rbenv/shims:/root/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

However, I run the ruby script by cronjob I get the following error message: Unable to find Mozilla geckodriver.

My Cronjob

*/20 * * * * ~/.rbenv/bin/rbenv exec ruby /home/path/to/the/ruby/script/report_export.rb

I start the ruby script so it all works. Can someone help me that it also works by cronjob

Solution

It could be that your export is located in place which is not called by cron daemon.

To investigate that replace your cronjob with echo $PATH >> /tmp/crontab.log and then check '/tmp/crontab.log' for PATH and check if /usr/local/bin is there.

Another reason could be that cron daemon is running as different user and thus has no access to geckodriver. Check ls -la /usr/local/bin | grep gecko. If that's the case, please checkout this SO question
