Methods like win.show() cannot be executed after packaging.

[stark tangle]

My friends, I need help. I used electron in vue-cil with the Plugin named "Vue CLI Plugin Electron Builder". With everything ready in background.js, I'm using electron:serve, and everything is fine. But after I packaged it with electron:build, I opened my program and some of the methods didn't get executed, here's why. win.show()and win.setMenu(null) and so on. Who can tell me why?

Packing is all right.

But this method is invalid win.setMenu(null)

[limber sphinx]

why do you think its invalid?

you load local file

or from dev server?

[stark tangle]

If it works, the menu bar in the red box will not appear

[limber sphinx]

from where you load this page?

[stark tangle]

electron:serve

=/

this is packaged app or development?

[stark tangle]

development

this is packaged

[limber sphinx]

what happens if you add win.removeMenu() to else block?

[stark tangle]

I'm trying.

god

.....

Actually works

I packed it. It worked

what did i begin to realize when you asked me to try something in "else"....So the above for development testing? ohhhhh...my god..

[limber sphinx]

probably

temporary env variables doesnt exists in packaged app

ok thanks bro, I really, I didn't realize that. I'm a Chinese and I didn't pay any attention to if (process.env.WEBPACK_DEV_SERVER_URL)... If I were more sensitive to English, I might find that...
