No Syntax Highlighting & No Language Features working

This is probably caused by VS Code not installing Vetur properly. Try these methods:

Vetur Crash

  • If it says cannot find module <some-module>, go to Vetur's client code installation directory and run yarn or npm install. This is usually caused by VS Code not correctly updating Vetur's dependencies from version to version. Paths:

    • Win: %USERPROFILE%\.vscode\extensions\octref.vetur-<version>\client
    • Mac: ~/.vscode/extensions/octref.vetur-<version>/client
    • Linux: ~/.vscode/extensions/octref.vetur-<version>/client

    You can also try uninstall/reinstall Vetur.

  • If it says problem related to memory and cpu, try to add a jsconfig.json or tsconfig.json and only include Vue-related code: https://vuejs.github.io/vetur/setup.html

Vetur can't recognize components imported using webpack's alias

  • You need to setup path mapping in jsconfig.json or tsconfig.json: https://www.typescriptlang.org/docs/handbook/module-resolution.html. For example:

    // Webpack
    module.exports = {
      resolve: {
        alias: {
          '@': 'src'
    // tsconfig.json
      "compilerOptions": {
        "baseUrl": ".",
        "paths": {
          "@/*": [

Vetur cannot recognize my Vue component import, such as import Comp from './comp'

  • You need to add .vue extension when importing SFC.

More details at: https://github.com/vuejs/vetur/issues/423#issuecomment-340235722

.vue file cannot be imported in TS file.

You need to add declare module '*.vue' in your dts files: https://github.com/Microsoft/TypeScript-Vue-Starter#single-file-components.

Formatting doesn't work in template section.

Vetur by default does not format html.
See https://github.com/vuejs/vetur/blob/master/CHANGELOG.md#vetur-formatting-changes for more detail.

If template still gets no formatting after enabling js-beautify, it is probably caused by prettier-vscode extension.
You can disable it for Vue: https://github.com/prettier/prettier-vscode#prettierdisablelanguages-default-

Install from source.

To build and install the extension from source, you need to install vsce.

Then, clone the repository and compile it.

git clone https://github.com/vuejs/vetur
cd vetur
cd server && yarn && yarn compile 
cd ../ && yarn compile 
vsce package

Now you'll find vetur-{version}.vsix, you can install it by editor command "Install from VSIX".
