"jekyll 3.6.2 | Error: Permission denied @ rb_sysopen" after Firebase deploy

Help
1

I have a blog hosted with Firebase. Using RubyInstaller for Windows - sometimes after deploying to Firebase, it’s no longer possible to build the jekyll website due Permission denied @ rb_sysopen

It seems this just randomly occurs after working some hours, see log below (just after a successful build and deploy):

jekyll 3.6.2 | Error:  Permission denied @ rb_sysopen - C:/Users/Liukang/Google Drive/MY-BLOG/liukang_blog/firebase-debug.log

I can’t open firebase-debug.log or delete it. I can “solve” the problem by shutting down the computer, which is frustrating.

Is this caused by not having correct file permission - if so, how do I setup the correct permission, so this doesn’t happen again?
