我自己也在找这个，这是我做的。
以main.js为单位

import { createApp } from "vue";
import App from "./App.vue";
import Rollbar from "rollbar";

const rollbar = new Rollbar({
  accessToken: process.env.POST_CLIENT_ITEM_ACCESS_TOKEN,
  captureUncaught: true,
  captureUnhandledRejections: true,
  payload: {
    environment: process.env.NODE_ENV,
  },
});

const app = createApp(App);
app.config.errorHandler = (err, vm, info) => {
  rollbar.error(err);
  throw err; // rethrow
};
app.config.globalProperties.$rollbar = rollbar;
app.mount("#app");
