Routes do not work properly

EDIT: Thanks for the answers, I tried all of the following, but good luck now. If I type localhosts / posts / new, it takes me to the form, however the link does not work when I click on the navigation bar. I updated the code and included the results of my rake routes.

I am new to ruby ​​and working on a tutorial, however one of my links is broken and not sure what is going on.

My navigation link for creating a new post does not lead me to the correct page, when I click on the "posts_path" link, the page does not change.

I can create new posts by typing / posts / new in the address bar, but when I click the "New post" link in the navigation bar, the page does not refresh (although the url displays / posts posts). Any idea how to fix this?
