当我尝试安装 therubyracer 时，出现以下错误:

Installing therubyracer (0.11.0) with native extensions

Gem files will remain installed in /home/carlos/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/therubyracer-0.11.0 for inspection.

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。

实际上，这有点棘手。

我使用我的习惯 dotfiles ，所以，我的 PATH 中有 ~/.dotfiles/bin。

我也是been noticed that the issue is related to python v3 vs v2 .

因此，修复非常简单，不会破坏我的系统:

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

像这样保留我的Gemfile:

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

然后 BOOM，它成功了。

谢谢大家的帮助。很抱歉延迟回复。

干杯

问题已在较新的 therubyracer 版本 (0.11.1) 中得到修复。
