if base is not '/' , this plugin can't get true path

[hahaxiaowai]

When the base is the default value, the MPA plugin work is normal，but if set other value, it can't find true path，Do I need to configure other content?

this is my config

  base: '/',
  plugins: [
    vue(),
    vueJsx(),
    mpa({
      // scanDir: "src/pages",
      // scanFile: "main.js",
      // scanFile: "index.html"
      open: './route',
    }),
  ],

  base: '/web/',
  plugins: [
    vue(),
    vueJsx(),
    mpa({
      // scanDir: "src/pages",
      // scanFile: "main.js",
      // scanFile: "index.html"
      open: './route',
    }),
  ],
