yntax Error: TypeError: loaderContext.getOptions is not a function

@ multi (webpack)-dev-server/client?http://localhost:8081/sockjs-node (webpack)/hot/dev-server.js ./src/main.ts

I upgraded my app from vue 3 js to vue 3 typescript and this error occurs when i try to start the dev server:

I tried to downgrade webpack to version 4, also the ts-loader to 8.2.0 and node version but non of these works.

Does anybody solved this issue?

I have same issue, after upgrading it to latest version

Me too. I used vue-cli to initialize a vue3 project and then executed vue add electron-builder.
Run npm run serve was successfully.
Run npm run electron:serve was faild.

 error  in ./src/background.ts

Module build failed (from ./node_modules/ts-loader/index.js):

I am also experiencing this issue on a vue 3 ts project

I found a workaround to downgrade only ts-loader v8 even if i use webpack@5.74.0.

yarn add -D "ts-loader"@"^8.4.0"

You need webpack v5 to use the latest version of ts-loader
