Question

我无法在 Yosemite 10.10 上安装 therubyracer gem。

Answer 1

gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.3' -- --with-system-v8

这是它在 10.10 (ruby 2.1.2) 上对我有用的唯一方法

或者尝试 gem install libv8 -v 'XX.XX.XX' -- --with-system-v8 添加 gem 的版本:)

Mac OS Catalina 的更新:

brew tap homebrew/versions
brew install v8@3.15
brew link --force v8@3.15
gem install libv8 -v 'XX.XX.XX' -- --with-system-v8
gem install therubyracer
