软件包安装由于unf_ext(0.0.5)gem而失败 [英] Bundle install failed due to unf_ext (0.0.5) gem

问题描述

我已经安装了ruby 1.9.3p327&在centos 6.3上使用rvm的rails 3.2.8.但是，在为特定项目文件夹进行捆绑安装时，该过程在尝试安装gem unf_ext 0.0.5时会失败，并引发以下错误，

I have installed ruby 1.9.3p327 & rails 3.2.8 using rvm on centos 6.3. But while doing bundle install for a particular project folder, the process fails in between when it tries to install gem unf_ext 0.0.5 and throws following error,

安装带有本机扩展的unf_ext(0.0.5) Gem :: Installer :: ExtensionBuildError:错误:无法生成gem本机扩展.

Installing unf_ext (0.0.5) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

宝石文件将保留安装在/home/rradmin/.rvm/gems/ruby-1.9.3-p327@r32/gems/unf_ext-0.0.5中以进行检查. 结果记录到/home/rradmin/.rvm/gems/ruby-1.9.3-p327@r32/gems/unf_ext-0.0.5/ext/unf_ext/gem_make.out

Gem files will remain installed in /home/rradmin/.rvm/gems/ruby-1.9.3-p327@r32/gems/unf_ext-0.0.5 for inspection. Results logged to /home/rradmin/.rvm/gems/ruby-1.9.3-p327@r32/gems/unf_ext-0.0.5/ext/unf_ext/gem_make.out

在安装unf_ext(0.0.5)时发生错误，并且Bundler无法 继续.确保gem install unf_ext -v '0.0.5'成功 捆绑之前.

An error occurred while installing unf_ext (0.0.5), and Bundler cannot continue. Make sure that gem install unf_ext -v '0.0.5' succeeds before bundling.

我也尝试如上所述分别安装unf_ext，但是出现了相同的错误. 我已经提到 https://github.com/cowboyd/therubyracer/issues/135 ，但仍然无法解决问题.请让我知道解决此问题的正确方法.

I also tried to install unf_ext separately as mentioned above, but got the same error. I have referred https://github.com/cowboyd/therubyracer/issues/135, but still not able to solve the problem. Please let me know proper way to solve this problem.

谢谢.

推荐答案

感谢Suman.但是我通过使用yum install gcc-g ++ libstdc ++-devel安装 libstdc ++-devel 解决了该问题.

Thanks Suman. But I resolved the issue by installing libstdc++-devel using yum install gcc-g++ libstdc++-devel.
