ruby-on-rails - 尝试安装 libv8 v3.11.8.9 时如何解决此问题？

Question

libv8 gem(v3.3.10 之后的任何内容)的安装失败并显示消息“Killed”。

我在我的 Gemfile 中包含了 libv8 和 therubyracer:

group :production, :staging do
  gem 'libv8'
  gem 'therubyracer'
end

bundle update在本地工作正常(Mac OS X)。当我做 cap staging deploy ，部署失败:

如果我转到服务器(Linode 上的 Debian 6 32 位，Linux 3.5.2-linode45)并运行 bundle exec gem install libv8 -v '3.11.8.9' ，它失败了:

目前，我必须指定旧版本的 therubyracer 和 libv8 才能使我的部署成功:

group :production, :staging do
  gem 'libv8', '~> 3.3.10'
  gem 'therubyracer', '~> 0.10.2'
end

好像this Issue可能是相关的。

有没有办法解决这个问题？

Answer 1

事情在 2013 年 1 月 7 日解决了……但一天后一切又崩溃了。又过了一天，看起来事情又恢复了!

therubyracer v0.11.1 现在再次依赖于 libv8 gem。因此，我的 Gemfile 已更改为:

group :production, :staging do
  gem 'therubyracer'
end

这将安装最新版本的 therubyracer (v0.11.1)，以及最新版本的 libv8 (v3.11.8.13)。这对我来说已经完全解决了这个问题 - 所以，therubyracer v0.11.1 & libv8 v3.11.8.13 gems 安装得很好。

如果您不是这种情况，那么仍有选择。对于仍然不会部署的 Rails 应用程序，我已经取得了成功:

group :production do
  gem 'libv8', '3.11.8.10'
  gem 'therubyracer'
end

也可以(并且可能是更好的选择)坚持使用已知良好的版本，直到通过将 Gemfile 更改为以下内容来解决所有这些问题:

group :production do
  gem 'therubyracer', '0.10.2'
end
