The Go environment should be fine.

leaanthony commented 2 months ago

Would recommend installing the latest version

leek-No1 commented 2 months ago

Hello. I think all of these should be the latest versions. Just now, I tried another graphical framework such as Lorca. When creating a window, it requires adding "--remote-allow-origins=*". If not added, the UI would be nil. Can this be added in Wails? 1722344179239 1722344241017

You're using an old version of Wails. Try upgrading it.
