Vue导入导致无法将对象错误的属性'exports'分配给只读属性

我目前正在将HTML模板迁移到Vue。 现在我开始导入存储在main.js文件中的Javascript文件 src .

我的文件如下:

import Vue from "vue";
import App from "./App.vue";
import router from "./router";

import pageLoader from "./assets/js/global/page-loader";
import tooltips from "./assets/js/global/tooltips";

Vue.use(pageLoader);
Vue.use(tooltips);

Vue.config.productionTip = false;

new Vue({
  router,
  render: (h) => h(App),
}).$mount("#app");

每个Javascript文件都位于 src/js 文件夹

但是,一旦我运行了应用程序,我就会收到以下错误:

Uncaught TypeError: Cannot assign to read only property 'exports' of object '#<Object>'
    at Module.eval (webpack-internal:///./src/assets/js/utils/plugins.js:56)
    at eval (webpack-internal:///./src/assets/js/utils/plugins.js:57)

    at eval (webpack-internal:///./src/main.js:15)

是什么导致了这个错误?如果能帮我解决问题,我将不胜感激。
