Yarn vue3 modify the name of the source file Error [Solved]

ERROR Failed to compile with 1 error PM 6:26:46
This relative module was not found:
* ./RoleFormDialog in ./node_modules/cache-loader/dist/cjs.js??ref–13-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref–1-0!./node_modules/@vue/cli-service/node_modules/vue-loader-v16/dist??ref–1-1!./src/views/Role/List.vue?vue&type=script&lang=js

Also change the directory where the source file is located to any other name (here it is changing Role to RoleAAA) and then change back to the original name (here it is changing back to Role), yarn will automatically clear the cache and the problem is solved.


[Solved] Vue binding dynamic inline style Error: transform:rotate()


V-bind or ‘:’ is followed by the written JS code, which is written in the form of key value pairs. The key is the CSS style attribute name of the tag, and the key is the attribute value. The key value must be a string or a variable (provided that the variable must be declared in the data first): style = “{transform: rotate()}” this writing browser calls rotate as a function rotate(), so an error will be reported


//String mode
:style="{transform: 'rotate(60deg)'} 
//Variable form
:style="{transform: `rotate(${Variable}deg)`}

rewrite the method of Localstorage (getitem, setitem, removeitem…)
the following record can be written:

function getStorage() {

    var storageImpl;

     try { 
        localStorage.setItem("storage", ""); 
        storageImpl = localStorage;
     catch (err) { 
         storageImpl = new LocalStorageAlternative();

    return storageImpl;


function LocalStorageAlternative() {

    var structureLocalStorage = {};

    this.setItem = function (key, value) {
        structureLocalStorage[key] = value;

    this.getItem = function (key) {
        if(typeof structureLocalStorage[key] != 'undefined' ) {
            return structureLocalStorage[key];
        else {
            return null;

    this.removeItem = function (key) {
        structureLocalStorage[key] = undefined;

cusSto = getStorage();

Vue Package Image Error: Syntax Error: Error: ‘**\node_modules\pngquant-bin\vendor\pngquant.exe‘

When packaging, an error is displayed at a picture path
Syntax Error: Error: ‘D:\work\tiny-sample\src\frontend\web\packages\src-entry\node_modules\pngquant-bin\vendor\pngquant.exe’

It can be seen that the package pngquant-bin reports an error, and the package is derived from the dependency of image-webpack-loader, so the root cause is image-webpack-loader.
Solution: delete the dependency image-webpack-loader, and then reinstall it. If it doesn’t work, try a few more times.

npm uninstall image-webpack-loader
npm install image-webpack-loader

If it still fails, set the image for NPM and repeat the above two steps

put 512×512 in the icons directory of the icon Png icon to complete packaging
for example:

After Vue is packaged to the server, the static resource path reports an error

The error reporting path is:
http: domain name/CSS/XX css

In fact, it should be:
http: domain name/dist/CSS/XX/CSS

ensure that the value of publicpath is: publicpath: ‘. /’

ps:config.js or Vue-config.js file, according to the actual situation, if the editor cannot be found, search publicpath globally

Vue3 Error: [vue/no-multiple-template-root] The template root requires exactly one element

vue3.0 supports <template/></template> tag to delegate more than one root element
Building the project with the latest Vite, the code in the default app.vue is as follows:

The code can run normally, but the vscode gives an error prompt:

The template root requires exactly one element. eslint-plugin-vue

The reason is that the vetur plug-in has not been updated

The temporary solution is

Settings -> Search: eslint plugin Vue -> Uncheck the first (Vetur › Validation: Template )
