For those who updated to High Sierra and who are receiving the error message shown If you are a Mac OS X user, who previously used Lich to enjoy Gemstone, please review below. If you have any questions - or if something below does not work, please let me know! Send an email to doug@play.net with details.
| Lich: error: $SAFE=2 to 4 are obsolete |
| lich/lich.rbw:2533:in `block (3 levels) in <class:Script>' |
| lich/lich.rbw:2533:in `block (2 levels) in <class:Script>' |
This is a known issue. The new Ruby version distributed in High Sierra (10.13) will not work with existing versions of Lich. We can recover you back to enjoying the game with Lich while using this new updated OS, but there are many variables and there may be some trouble shooting involved. I've tried to lay out some preliminary steps to get us all to a consistent point.
| First, do you have RBENV installed | |
| In terminal window type the following: | |
| rbenv version | |
| If you get a version returned, you have | |
| RBENV installed. If that version is 2.0 | |
| or higher, and you were playing the game | |
| with Lich, you should be ok! One step. | |
| For this step to work, you have to type the | |
| version of Ruby that was displayed in the | |
| command above (important). Here, the | |
| command we returned was 2.2.5pXXX, so | |
| In terminal window, type the following: | |
| rbenv global 2.2.5 | |
| Then you're ready to test! |
| If you do not have RBENV installed | |
| Things are much trickier, but we will | |
| overcome! | |
| First, you will very likely need to | |
| reinstall your command line tools. | |
| In terminal window, type: | |
| xcode-select --install | |
| If that fails to execute properly then | |
| you will need to go to the Mac AppStore | |
| and download the entire xCode suite. | |
| This is a large (5GB+) download and | |
| takes a bit of time to install, but | |
| should work if the above fails. | |
| When you have tools installed, now we set | |
| up the rest of the environment. | |
| In terminal: | |
| brew pin cairo | |
| brew pin pango | |
| brew pin gtk+ | |
| Please do not proceed until you have | |
| successfully entered the three commands | |
| above. If you do not PIN these brews | |
| the difficulty in correcting your system | |
| so that everything works goes up significantly! | |
| In some cases, we may simply have to restore your | |
| old OS, or do a completely fresh install. So | |
| please, execute those three commands before | |
| proceeding. Thank you. | |
| brew update | |
| brew install rbenv | |
| echo 'eval "$(rbenv init -)"' >> ~/.bash_profile | |
| Then exit all open terminal windows (important) | |
| Open a new terminal window and continue: | |
| rbenv install 2.2.5 | |
| rbenv global 2.2.5 | |
| rbenv rehash | |
| which ruby | |
| ruby -v | |
| Check the results | |
| Should clearly say /Users/you/.rbenv/shims/ruby | |
| Should clearly say ruby 2.2.5p319 | |
| If it does not, please stop and email doug@play.net | |
| If it does, continue in terminal window: | |
| gem install sqlite3 | |
| gem install gtk2 | |
| At this point, you're ready to update to 10.13 | |
| but you must also do this after you update | |
| Also, If you already have RBENV installed | |
| you will need to take this step after you update | |
| In terminal window (after update): | |
| rbenv global 2.2.5 | |
| Now you're ready to test! |
Please help us as a community - let us know here, or email me, of the results so that we can track and build a bullet-proof scheme for those who follow.
