After upgrading to Mac OS Big Sur, I saw this error I haven’t seen before:
So I ran bundle install
but it didn’t seem to work either. An excerpt from the terminal output:
@geqian007 Enable VPN tunneling option on the user role (general tab) and configure the supporting policies under users resource policies vpn tunneling access control (control the traffic allow/deny), connection profiles (IP scope, encryption&transport type, etc.), split tunneling (name implies ). Then if your computer is from 2011 or later you use Internet Recovery for OS X: Install Mavericks, Lion/Mountain Lion Using Internet Recovery. Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
After some research and trial and error, I found this precious answer in Stack Overflow that it is due to the Ruby version that is not compatible with BigSur and it should be at least 2.7. So Ichecked Ruby releases and decided to go with one of the most recent releases: 2.7.2.
Anyway, steps I think worked:
And it worked!
Installing Ruby through Homebrew: didn’t solve the issue but I don’t know if this actually and eventually helped or not.
Installing the latest version of Ruby (ref) using rvm: didn’t update the version for some reason.
