Vue 3 package version mismatch

Question

I'm trying to update a package I made to vue 3, and I'm facing an issue with vue-template-compiler.

I tried to follow a similar post that had some kind of a similar problem but it doesn't seems to work for me.(Vue package Version mismatch)

I got the following error:

> @utt/[email protected] build:es
> cross-env NODE_ENV=production rollup --config build/rollup.config.js --format es

[!] Error: 

Vue packages version mismatch:

- [email protected] (C:\projects\UTT-Message-System\module\node_modules\vue\index.js)
- [email protected] (C:\projects\UTT-Message-System\module\node_modules\vue-template-compiler\package.json)

This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.

Update: I used rollup-plugin-vue package, and its not compatable with vue 3, so I installed rollup-plugin-vue@next and now I don't get vue-template-compiler inside my package-lock.json file.

But now I have a new error on the plugin babel, and I'm trying to resolve this issue, so if anyone can share any ideas it would be much appreciated:

Thanks for the help.

Answer 1

remove "vue-template-compiler" from your app with

npm uninstall vue-template-compiler

then install compiler-sfc which replaces vue-template-compiler

npm i -D @vue/compiler-sfc

make sure there is no vue-template-compiler on your package.json and you see vue/compiler-cfs

since you've removed vue-template-compiler then vue-loader will complain to need it to work so upgrade it as well to work for vue 3 with the following command

npm install vue-loader@next

since you're doing upgrade, there might happen other errors here and there depending on your project configuration. but keeping on solving, soon you'll get it running
