Detailed explanation of Vue3 package publishing test error problems and solutions

Vue Family Bucket has always been one of the important technology stacks for front-end development. Recently, Vue3 version has been officially released. Compared with Vue2, it will be more efficient, faster and more flexible, which has attracted the attention of developers. However, when we test the package release of Vue3, we may sometimes encounter some error reporting problems. The following will introduce in detail the error reporting problems and solutions of Vue3 package release testing.

1. Error message

1. When we run npm run build, the following error message may appear:

ERROR in /path/to/project/src/index.ts
1:0-40:11
TS2344: Type 'string' does not satisfy the constraint '(...args: any) => any'.
  Type 'string' is not assignable to type '(...args: any) => any'.
    1 | import { createApp } from 'vue'
    2 | import App from './App.vue'
  > 3 | import Demo from './components/demo/index'
      | ^
    4 |
    5 | createApp(App).mount('#app')

2. When we run npm publish, the following error message may appear:

npm ERR! code E403
npm ERR! 403 Forbidden: @my-package-name

The above two errors are common in Vue3 package release testing. The problems, specific causes and solutions will be introduced one by one below.

2. Reasons for error reporting and solutions

1. TS2344Error

We can briefly analyze the reason for this error reporting, typestring cannot meet the requirements of function type (...args: any) => any, which shows that there may be such a situation in our code-in the imported module, a The string is assigned to a variable of function type.

Solution: We need to check whether the code is referenced and assigned according to the function type. If there are problems, we need to make corresponding modifications.

2. npm publish 403 Forbidden error

The reason for this error is relatively simple and clear. The reason for this error may be that the name of the package has been occupied by someone else, or It's because you don't have permission to publish this package.

Solution: We can first check whether the package name is already occupied by someone else. If the package name is not occupied, we can check whether we have logged in to the npm account correctly, or whether we have permission to publish the package. If the problem still cannot be solved, check the npm official website or official documents for related solutions.

3. Summary

The above are the problems that may arise during the Vue3 package release test and the corresponding solutions. I hope it can help developers who encounter problems. Of course, the problems faced by each developer may be different, and we need to analyze them one by one according to the specific situation to find a suitable solution. The ultimate goal is to enable our Vue3 project to be successfully released so that we can conduct front-end development more efficiently.
