functions.php errors since update to Version: 2.2

I updated the theme on 5/18, and now the twentyseventeen error_log is logging errors in functions.php:

The lines in error are:
/**
* Twenty Seventeen only works in WordPress 4.7 or later.
*/
if ( version_compare( $GLOBALS[‘wp_version’], ‘4.7-alpha’, ‘<‘ ) ) {
require get_template_directory() . ‘/inc/back-compat.php’;
return;
}

I also updated to WordPress 5.2, and php is at v7.0.33

The site is up and running, however.
