Answer 1

I updated to macOS Catalina @ 10.15 and ruby 2.6.5. After a while got libv8 and therubyracer to install again, although I'd recommend not to update macOS yet (I heard ruby should be fine).

First, I had to update XCode

1. xcode-select --install

I used rbenv to update ruby, and set the ruby version manually in /Users//.rbenv/version to 2.6.5. Although this shouldn't matter if your project contains a .ruby-version file.

Then I cleaned up any version I installed fro libv8 (usually in /usr/local/opt/): brew uninstall v8, brew uninstall libv8@3.15

2. brew install v8@3.15

Now, following https://github.com/cowboyd/libv8#do-i-get-a-binary, I installed

3. gem install libv8 -v '3.16.14.19' -- --with-system-v8

and then could run bundle install without errors.
