我试图在VirtualBox Ubuntu 14.04上启动我的rails应用程序，但出于某种原因，每次我使用任何rails或gem命令（如rails s或bundle install时，我都会收到以下错误消息：

/home/jakup/.rbenv/versions/2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/ext/builder.rb:159:in `synchronize': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError)

    ERROR: Failed to build gem native extension.

过去我在VirtualBox上将网络适配器设置为桥接网络时曾经出现此错误，但现在即使我没有在桥接网络上发生此错误，也有任何想法？

答案 0 :(得分：0)

我会写一个答案的形式，只是为了更容易写。

您要删除所有以前安装的宝石（例如手动删除宝石）并尝试重新安装它们。它应该工作。

不要删除这些（忽略宝石的版本）：

rake (10.4.2)
rdoc (4.2.1)
rubygems-bundler (1.4.4)
rvm (1.11.3.9)
gem-wrappers (1.2.7)
bundler (1.11.2)
bundler-unload (1.0.2)

此外，尝试在.bundle目录中安装不在全局命名空间中的gem。首先安装它，如bundle install --path .bundle，我想每次下次它将使用该目录

答案 1 :(得分：0)

我找到了一个（临时？）解决方案..

当我在本地运行项目时出于某种原因，我在Windows（主机）和ubuntu（虚拟机中的guest）之间的共享文件夹中运行项目，因此不在共享文件夹中，我卸载文件夹，它可以工作。 / p>

不要问我为什么有效的细节，它只是出于某种原因神奇地做了。
