How can replace a string within single quotes with a value stored in a variable?

Question

I want to use a sed command in as script to change the Ansible version in a file from '2.7' to 2.9 and keep the single quotes, '.

This is what I use, but it seems like the result does not have the single quotes:

sed -i 's/^ansible::version:.*/ansible::version:'$vers'/' /path_to_file

output:

ansible::version: 2.9

This is the content of the file:

ansible::version: '2.7'

@jared_mamrot No need to escape single quotes within a double quoted string, also not for BSD sed. — Benjamin W., Sep 03 '20 at 03:31
@jared_mamrot ...but the `.` *should* be escaped, or it matches anything ;) — Benjamin W., Sep 03 '20 at 03:41

BSD sed: sed "s/'2\.7'/'2\.9'/g" file & GNU sed: sed "s/'2\.7'/'2\.9'/g" file
