`cachedir` argument causes error when app run

[anhhuy1605]

When I run electron app with cachedir argument electron . -c ./.cache/ to specify the cache directory of electron-compile, it runs correctly if ./.cache/ directory does not exist, but when I close and run the app again (./.cache/ is created and populated with cache data), it threw this error:

App threw an error during load

I don't get that error when I run without the cachedir argument (electron-compile will use the default temporary directory cache compileCache_)
