Why does nodejs turn all the pages into source code and display them on browsers?

the project was supposed to be fine yesterday. What happens when you run the project today and find that the page is all displayed in source code on the browser?
none of my code has been modified.

art-template template engine used to render pages

there are several pages that can still be displayed. But when I switched back and forth, it also became source code.

F12 looks at it and finds that there is a pre tag that wraps the original page source code.

ask the Great God for guidance on what"s going on. This is not the problem of my source code, the source code has not been changed, there is no modified record.


first of all, the pre tag is displayed in the form of source code
art-template template engine rendering page tag should be {- sharphtml}}

are you satisfied with both of these points?
