Since grive no longer works with new Google API, how do I mount Google Drive?
I think this may help you, it is an alternate to Grive tools.
Installation of "overGrive", the new Google Drive client:
Step 2: Launch OneGrive from launcher.
Step 3: A window will appear - click on Connect account.
Then a browser window will open for you to
sign in to your Google account.
Step 4: At the end you will get a code.
Copy this code and paste it in the overGrive window at Account entry box and click validate.
Step 5: After setting your preferences (like location, etc.) click Start Sync.
