I can't install QuickSubmit. There is an error that
"The tar command is not available. Please correctly configure it in your "config.inc.php"."
What can I do in order to install it?
You are using OJS 3.0.2, right?It seems that you need the TAR command/executable on your server and/or you would have to enter the correct path to it in your OJS file config.inc.php https://github.com/pkp/ojs/blob/master/config.TEMPLATE.inc.php#L436. -- It is needed for the plugin package to be extracted and the files copied at the correct destination.There is one more way to install the plugin:You can get the plugin package from here: https://github.com/pkp/quickSubmit/releases. Unpack it i.e. copy the unpacked plugin folder quickSubmit/ into the OJS folder plugins/importexport/. Then run this command from your OJS folder: php tools/upgrade.php upgrade. But please do the backup first, before executing this command!!!
php tools/upgrade.php upgrade
Thank you so much. It worked.
