How to fix Vue packages version mismatch from vue-loader?

Question

I am trying to install the Vue Filemanager to my package.json. However, when I try to install the package using npm install and npm run dev I get this error:

ERROR in ./resources/assets/js/file-manager/FileManager.vue
Module Error (from ./node_modules/vue-loader/lib/index.js):


Vue packages version mismatch:

- vue@2.6.10 (/var/www/node_modules/vue/dist/vue.runtime.common.js)
- vue-template-compiler@2.6.14 (/var/www/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.

I have vue-loader 7.11.2 installed (its a leagacy project). I did not find any instructions how to reinstall vue-loader, but upgrading vue-template-compiler alone did not work.

I also tried the following solutions:

• https://github.com/vuejs/vue-loader/issues/470#issuecomment-292971628 Did not work

• https://stackoverflow.com/a/43398218/2311074 could not use it, because my versions of vue and vue-template-compiler are higher

• https://stackoverflow.com/a/51887838/2311074 same with, versions are too low

• https://stackoverflow.com/a/48368175/2311074 did not work

• https://stackoverflow.com/a/63777607/2311074 did also not work

Here is my package.json

Any ideas how to fix this?

Answer 1

vue and vue-template-compiler must have the same version number. This also cost me some nerves once.
