How to solve the problem of vue package not displaying error

With the rapid development of front-end technology, more and more companies are beginning to use Vue as a front-end framework. Vue's high development efficiency and strong adaptability to existing projects have become the main reasons why companies choose Vue. However, in the process of using Vue, sometimes we encounter the problem that the page does not display or an error is reported after packaging. Today we will take a look at the solution to the problem that Vue packaging does not display an error.

1. Check the packaging configuration

Many times, the packaging is not displayed or an error is reported because we have problems in the packaging configuration. We need to recheck our packaging configuration to ensure that all configurations are correct. .

1. assetsPublicPath configuration issue

We can find the assetsPublicPath configuration item in the config/index.js file, which specifies the suffix path of the static file generated after webpack compilation , if the configuration is incorrect, there will be problems with the path of the static files after packaging, resulting in the page not being displayed or an error being reported.

Correct configuration:

production: {
  // Paths
  assetsRoot: path.resolve(__dirname, '../dist'),
  assetsSubDirectory: 'static',
  assetsPublicPath: './' // 正确设置
}

2. vue-router routing configuration problem

If the page uses vue-router for route jump, then we need to check Check the routing configuration to ensure that the routing configuration is correct.

Correct configuration:

// app.js
import Vue from 'vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter);

// router.js
import Vue from 'vue';
import Router from 'vue-router';
import HelloWorld from '@/components/HelloWorld';

Vue.use(Router);

export default new Router({
  routes: [
    { path: '/', name: 'HelloWorld', component: HelloWorld }
  ]
})

2. Check component references

When we develop Vue projects, we will use many components. If the component reference is incorrect or the component path is incorrect, the page will not be displayed or display abnormally.

We need to check whether the component reference is correct. If there is an error, we need to adjust it.

Correct configuration:

import Vue from 'vue';
import App from './App';

new Vue({
  el: '#app',
  components: {
    App
  },
  template: '<App/>'
})

3. Check dependencies

If we use certain dependencies in the Vue project, then we need to check whether these dependencies are correct. If certain dependencies are missing, the page will not be displayed or display abnormally.

We can use the npm install command to reinstall all dependencies, or manually check for missing dependencies and reinstall them.

4. Check the code logic

Finally, if the above three methods cannot solve the problem, we also need to check the code logic. We need to carefully evaluate the logic errors in the code and try to adjust them.

We can use Vue Devtools to debug the code, analyze it based on the error information output by the console, and make adjustments to the code logic.

Summary

The above four methods are the main methods to solve the problem of vue packaging not displaying errors. When we use Vue for development, we need to carefully evaluate the possibility of various problems and make targeted adjustments. Only in this way can we make the development process of the Vue project faster, optimized and efficient.
