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。

Answer 1

实际上，这有点棘手。

我使用自定义dotfiles，因此，我的路径中有~/.dotfiles/bin。

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

所以，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

离开我的Gemfile：

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

和BOOM一起工作。

感谢您的帮助。很抱歉延迟回复。

干杯

修改

问题在较新的therubyracer版本（0.11.1）中得到修复。

Answer 2

我在ArchLinux中遇到了同样的问题。这是known issue。通过在0.10.2

中添加以下行，锁定到Gemfile的解决方法适用于我的archlinux

gem 'therubyracer', '0.10.2', :platforms => :ruby

我测试了这个＆amp;它至少可以在64位上运行。希望它对你也有用。

Answer 3

我强烈建议使用外部Node.js（我相信有一个正式的包），然后使用sstephenson / execjs。

如果你使用的是Rails，它已经依赖于ExecJS，所以你可能只是删除对therubyracer的依赖，捆绑，安装Node.js，你就可以了。

Answer 4

您需要安装libv8 3.11.x才能获得最新版本的therubyracer。所以尝试更新libv8然后再捆绑。

我无法在Arch Linux x64中安装therubyracer
