Post author not showing in the sidebar

https://codex.www.ads-software.com/Template_Tags/the_author_posts_link

1st paragraph states:
This tag must be used within The Loop.

I am using it inside the loop

here is the exact code

<?php $postlist = get_posts(‘category_name=events&numberposts=5’);
foreach ($postlist as $post) :?>
” rel=”bookmark”><?php the_title(); ?>
<?php the_time(‘M d, Y’); ?> | By: <?php the_author_posts_link();?>
<?php } $i++; endforeach; ?>
