Red Hat Linux + Rails + RVM：Gem :: Installer :: ExtensionBuildError：错误：无法构建gem本机扩展

Question

因此，我试图将Rails 3应用程序部署到使用RVM的Red Hat Linux服务器上，但是它始终会失败：

    ** [out :: myserver.server.com] Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

因此，我听了指示，并确保可以通过SSH到服务器并运行gem install debugger-linecache -v '1.1.2' -v'1.1.2'来确保gem可以在该服务器上gem install debugger-linecache -v '1.1.2' ，甚至可以转到服务器并手动克隆git repo并运行bundle install以便所有gems都存在于该服务器上。 但是，即使那里有所有宝石，只要部署，我仍然会收到相同的消息。 我以任何用户身份登录，然后输入gem list ，所有宝石都会显示出来。 这些宝石也看起来像是全球性的，并且位置正确：

[emai@511863-web3 ~]$ which gem
/usr/local/rvm/rubies/ruby-1.9.3-p448/bin/gem    

有谁知道我该如何解决？

Answer 1

所以我只是听了Geoffroy的声音，并安装了rvm-capistrano gem，并将这些行添加到我的capistrano脚本中

set :bundle_dir, ''
set :bundle_flags, '--system --quiet'
set :rvm_type, :system

而且有效！
