upgrade @quasar/appV2
Error Failed to compile with 1 errors
error in ./.quasar/client-entry.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: [BABEL] F:\spyw\sxapp.quasar\client-entry.js: Invalid Option: bugfixes is not a valid top-level option.
Maybe you meant to use 'modules'? (While processing: "F:\spyw\sxapp\node_modules\@quasar\babel-preset-app\index.js.overrides[0]$0")

This is either very specific to your code or your modules are messed up.
Delete node_modules, delete yarn.lock. Run yarn install.
Note: If you're using npm for local deps, move to yarn please. NPM is too buggy.
thanks I made it. But IE11 prompt after successful compilation vendor.js syntax error
`
class Features {
.......................
}
`
Have you followed these instructions: https://quasar.dev/quasar-cli/browser-compatibility#IE-11-Support ?
This is how I configure it. On the right is an error opened with ie11

What is the exact error you're getting ?
鈥渂rowserslist":[
"ie 11"
]
IE11 is not as accurate as this. After looking at the compiled code, there is still a 'class' syntax and' = > 'function. Can you take a look at your configuration method
You have "last 3 version, not dead, ie >= 11",
Can you try explicitly adding "ie 11" so it becomes:
"browserslist": [
"ie 11"
]
Yes, I tried But it didn't work
Can you provide a reproduction example? Or email me your source to try to allan (at) quasar.dev?
Given your original path was F:\spyw\sxapp.quasar\client-entry.js I'm assuming you were playing around with something (should be .quasar, not sxapp.quasar) so I wonder if something else is broken in your project.
We'll reopen once relevant info is added.
