Error: Cannot find module '@vue/babel-preset-app'

Adding @vue/babel-preset-app as one of the devDependencies should solve the issue.

If you are using npm, do

npm install @vue/babel-preset-app --save-dev

for yarn

yarn add @vue/babel-preset-app --save-dev

for pnpm

pnpm install @vue/babel-preset-app --save-dev

I solve this issue, after run this command. npm install @vue/babel-preset-app --save-dev

then it throw me this error Module build failed (from ./node_modules/@vue/cli-plugin-babel/node_modules/babel-loader/lib/index.js)

I launched the following command npm install -D babel-loader @babel/core @babel/preset-env webpack

it gave me a new error Failed to resolve loader: vue-style-loader

after that I run a npm install vue-style-loader

and it gave me another error angain, this one Error: Loading PostCSS Plugin failed: Cannot find module 'autoprefixer' Finally I run the next following command, npm i autoprefixer and It worked for me.
