An error occurred while installing therubyracer (0.11.0), and Bundler cannot continue.
Make sure that `gem install therubyracer -v '0.11.0'` succeeds before bundling.

我不知道发生了什么.

推荐答案

实际上，这有点棘手.

我使用我的自定义 dotfiles，所以，我有 ~/.dotfiles/bin 在我的路径中.

I use my custom dotfiles, so, I have ~/.dotfiles/bin in my PATH.

我还注意到该问题与 python v3 与 v2 相关.

所以，修复非常简单，不会破坏我的系统:

So, the fix was pretty easy, without break my system:

ln -s /usr/bin/python2 ~/.dotfiles/bin
reload
gem install libv8 --verbose
bundle

像这样离开我的Gemfile:

[...]
gem 'therubyracer', :require => 'v8', :platforms => :ruby
[...]

BOOM，它奏效了.

谢谢你们的帮助.抱歉延迟回复.

Thanks for your help guys. Sorry for the delay to reply.
