# Course Portal Setup Issues / Fixes *Note: I'm on an M1 mac that I migrated from an Intel mac using Mac's migration utility.* ### 1. Installing Ruby `rvm install 2.6.3` would not work without: 1. `brew update` 2. `xcode-select --install ` ### 2. Compiling Ruby Had ruby compile error, the included instructions about libffi fixed it. ### 3. Rake setup Problem: `rake setup` gave rake version mismatch error. Fix: `bundle exec rake setup` ### 4. Default URL for OAUTH Currently says `http://codepath.com`, should it be .org? ### 5. padrino s -p 3001 Problem: "No runtime (js)" error Fix:`ibrew install v8` Problem: ```bash ...mini_racer-0.4.0/mini_racer_extension.bundle, 0x0005): symbol not found in flat namespace '__ZN2v811ArrayBuffer9Allocator19NewDefaultAllocatorEv' (LoadError) ``` Fix: ?!?!?!
