vue webpack template missing parser

问题

I was just setting up a vue project using the webpack template like stated here: http://vuejs-templates.github.io/webpack/

However after running npm run dev just to test that the template is working, I get this error:

Failed to compile with 2 errors                                                                                                                                                                                                                                                           21:49:02

What am I doing wrong?

回答1:

Prettier has caused this regression in their 1.13.0 update which occurred today. Downgrade to the previous version to fix this error:

npm install --save-dev prettier@1.12.0

npm run dev

That should do the trick.

回答2:

If you're using Yarn add this to your package.json to force @vue/component-compiler-utils to use the right version:

"resolutions": {
  "@vue/component-compiler-utils/prettier": "1.12.1"
}

Then do a fresh install.

回答3:

it is fixed in vue-loader@13.7.2 and vue-loader@14.2.3. So just upgrade.

回答4:

If you are using laravel-mix then this fixed it for me:

Remove .\node_modules, remove .\yarn.lock then add following to .\package.json

"dependencies": {
    ...
    "prettier": "1.12.1",
    "vue-loader": "13.7.0"
    ...
},
"resolutions": {
    "laravel-mix/vue-loader": "13.7.0",
    "vue-loader/prettier": "1.12.1"
}

run yarn and all should be working.

回答5:

Since vue-cli uses prettier API interface here and hardcoded the options, and prettier dependency was added in project @vue/component-compiler-utils.

You could try npm i prettier@~1.12.0 to force the prettier version here.

BTW someone did a pull request with the fix

回答6:

I got the same error with yarn, but tried npm i and npm run dev instead and it worked.

yarn v v1.5.1 npm -v 5.6.0 node -v v10.0.0

回答7:

I use Nuxt/Vue on Docker. I got same error with docker build.

It doesn't work after below commands

rm -rf node_modules 
npm install --save-dev prettier@1.12.0
npm run dev

So I edited Dockerfile like this and it worked.

FROM node:8.11

RUN mkdir -p /app
COPY . /app
WORKDIR /app

RUN npm install && npm cache verify
RUN npm install --save-dev prettier@1.12.0
RUN npm run build

EXPOSE 3000

CMD ["npm", "run", "express"]
