At prepare(), npm wants to use the global ~/.npm cache. This is not ideal (and can fail if the home is not writable). This can be fixed by appending --cache npm-cache to npm install.

When downloading caprine - it attempts to download electron29 with its enormous git history. To avoid this you can just download electron29-bin before downloading caprine.

yay -S electron29-bin
yay -S caprine

Can confirm, builds with electron34

Not sure what change happened, but caprine doesn't launch anymore for me after a recent update that involve reinstalling electron29 and electron34 side by side for another app.

Sometimes I get:

APPIMAGE env is not defined, current application is not an AppImage
checkForUpdatesAndNotify called, downloadPromise is null

And other times I get no output at all. Caprine just fails to run and no amount of --verbose or --trace-warnings will give me an idea as to what is wrong.

Maybe move out of electron30 and use a more recent version ?

For anyone who tries to install this package and the electron29 starts downloading around 80GB of git history. Try to manually install the pre-built electron29-bin before installing caprine, to avoid this.

Works fine also with electron 30.

package seems broken, just displays meta logo and gives me weird GLSL errors in stdout.
