Running into "couldn't infer parser" error using vue-cli

Question

I'm getting an error repeatedly when trying to build a new webpack project using vue-cli. I'm following along with the docs on the latest build (3.0.0-beta.11), also tried with an earlier version, which wasn't beta.

When I run yarn serve it attempts to start the dev server and build the project but fails here:

error  in ./src/App.vue?vue&type=template&id=7ba5bd90

Module build failed: Error: No parser and no file path given, couldn't infer a parser.

About my setup

• Mac OS
• I'm running node v8.5.0
• packages are installed with yarn

The Things I've Attempted

• Different versions of vue-cli to generate a new project. The projects generate and install modules.
• Tried removing the prettier module, but the error still seems to come up.
• Tried reinstalling all modules.

What else might I try to get past this error?

Answer 1

Removing the current node_modules folder from the project, adding "prettier": "^1.12.1" to package.json and running npm install solved the issue.

Another option is to run npm install [email protected] without removeing the node_modules folder before

Update:

For some users, verion 1.12.1 did not work

@Kivin proposed another solution that can be found here: vue webpack template missing parser

Answer 2

Known issue and it will be fixed in the next version of vue-cli

In prettier 1.13.0, default parser was removed with a minor version(used to be babylon)

Issue: https://github.com/vuejs/component-compiler-utils/issues/14

Issue at prettier repo: https://github.com/prettier/prettier/issues/4567

Sorry, we committed the age-old semver sin- we knew this was a breaking change, but because it would only affect a subset of our users, we didn't bump the major version, because we didn't want to create friction for our users to upgrade.

To get the old behavior, add parser: "babylon". You may also want to lock prettier to a specific version in your package.json.
