TypeError: Cannot read property 'parseComponent' of undefined

[jbnv]

After doing npm update, my npm run dev is throwing a bunch of instances of one error:

TypeError: Cannot read property 'parseComponent' of undefined
at parse (node_modules/@vue/component-compiler-utils/dist/parse.js:14:23)
at Object.module.exports (node_modules/vue-loader/lib/index.js:67:22)
@ ./resources/js/routes/index.js 18:11-28
@ ./resources/js/sp.js
@ multi ./resources/js/sp.js

The errors are all the same except for one difference: the reference 18:11-28 for ./resources/js/routes/index.js is different for each file. It looks like each error corresponds to an () => import() statement.

I would definitely appreciate some assistance on this since it's crashing my project's entire build.

A reproduction with your package-lock.json or yarn.lock would help.

I'll try at some point to shrink the entire project down to something that I can post here. In the meantime, here's the package-lock.json.

Hi there,

Same problem here. Here is a reproduction: https://github.com/wearemd/spa-starter/tree/renovate/sass-loader-8.x.

It happens after updating to sass-loader-8, so it's a sass-loader issue?

Sorry about that, I haven't any error.

Gee thanks, I wanted to look at your reproduction to see how it compared to my code...

I resolved my issue by changing the version of vue-template-compiler from ^2.6.10 to 2.6.10.

It also happens when vue-template-compiler is missing.

I removed package-lock.json file and node_modules directory and reinstalled npm packages. Then I resolved the issue.

$ rm package-lock.json
$ rm -rf node_modules
$ npm install
$ npm run serve

I met the same problem, and here is no package-lock.json file.Does anyone know how to fix it?

Personally, matching vue and vue-template-compiler versions (using vue 2.6.12 and vue-template-compiler 2.6.12) fixed the problem for me.

如何解决的？

@HYLijing
just make sure "vue" , "vue-template-compiler" and "vue-server-renderer" catch up to the same version of 2.6.12

I've tried your method, but my problem still hasn't been solved.
