Vue dist path for CSS and JS not found

问题

I am having trouble rendering my VueJS application after build. When I look in the build folder and examine the paths, there is a forward slash at the beginning of my paths to my assets, css and javascript. This makes it so my css, assets and javascript cannot be found. I am wondering how, before I run the build script, I can avoid this issue. Thank you. Here is my code:

App.vue

<template>
  <div id="app">
    <BaseTimer />
    <!-- <PomodoroTimer /> -->
  </div>
</template>

<script>
import BaseTimer from "./components/BaseTimer";
// import PomodoroTimer from "./components/PomodoroTimer";

export default {
  name: "App",

  components: {
    BaseTimer
    // PomodoroTimer
  }
};
</script>

<style>
body {
  background-color: #fff;
}

#app {
  font-family: "Avenir", Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  width: 100%;
}
</style>

BaseTimer.vue (inside the components folder - within the src folder)

<template>
  <div class="base-timer">

        <path

回答1:

By default, the path points to the server root. That means / if serving the files statically on a web server like Apache/node, or even directly in c:\ if double-clicking on Windows, for example.

Assuming you're using the Vue CLI, you can configure this location by editing-- or creating-- vue.config.js in your project root using publicPath:

module.exports = {
  publicPath: process.env.NODE_ENV === 'production'
    ? '/your/path/to/dist/'
    : '/'
}

This lets Vue serve the dev server at / as expected, and uses the other path in production. The CLI automatically sets process.env.NODE_ENV if you're wondering. Don't forget to rebuild after modifying this file.
