How to fix vue packages version mismatch

In this article, you are going to learn about how to fix vue packages version mismatch.

VueJS is a powerful JavaScript front-end library that is used in single-page applications. While working with VueJs you may have faced this type of problem: “fix vue packages version mismatch” and didn’t figure it out how to solve this problem. In this article, I will show you why this problem is occurring and how to solve it. See the error below:

The main reason behind it is the version of vue and the version of vue-template-compiler are not matching. Let’s see the solution for it in the below section.

solution: If you see the messages right after the error you will get some hints of how you can solve this error. It is said that this may cause things to work incorrectly, Make sure to use the same version for that. Let’s follow this. For example, you are working with an older version of vue. All you need to do is to use the same version for both. like:

npm i vue@2.6.14
npm i vue-template-compiler@2.6.14

This will solve your problem. If you are still getting this error you may follow an alternative approach. First you need to modify your package.json file. See the below example:

"dependencies": {
    "vue": "^2.6.14",
},
"devDependencies": {
    "vue-template-compiler": "^2.6.14",
},

You may set the version based on the current version you are using but make sure you use the same version for both of them. after that you need to delete your existing node_modules and package-lock.json file and finally run npm install. This may solve this problem.

Make sure you also updated vue-loader. As the error message has shown that “ 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.” That means if you are using vue-loader which is greater than 10.0 then you need to update the vue-template compiler by giving the command :

npm update vue-template-compiler

If the version of vue-loader is below 10.0 then you need to reinistall it. These are some approaches and by following it you may solve this problem successfully.
