I used Express to write a web application and used chartjs to generate charts, but the browser could not load the Chart.bundle.min.js file.
Chrome59 and Firefox have been tried, but they cannot be loaded; I accessed 127.0.0.1/js/Chart.bundle.min.js and it can be accessed, indicating that there is no problem on the server side. Next, there is indeed a script tag that loads the js in the html, but the file is not in the debugging tool source.

Guess: In the Elements panel of Chrome DevTools, the src attribute of the other script tags are underlined. The underline indicates that this is a URL. Only the src attribute of the script tag of chartjs is not underlined, indicating that Chrome doesn't treat it as a URL, so the file won't be loaded. But why doesn't Chrome parse it into a URL?
