Fiware 我的PeP代理安装缺少什么？

我正在安装PeP代理

我已在CentOS 6.7上安装了node和npm：

[root@centos fi-ware-pep-proxy]# node -v
v0.10.41
[root@centos fi-ware-pep-proxy]# npm -v
1.4.29

但是，当我进入fi ware pep proxy文件夹并运行

npm install

时，出现以下错误：

[root@centos fi-ware-pep-proxy]# npm install
npm WARN deprecated This version of npm lacks support for important features,
npm WARN deprecated such as scoped packages, offered by the primary npm
npm WARN deprecated registry. Consider upgrading to at least npm@2, if not the
npm WARN deprecated latest stable version. To upgrade to npm@2, run:
npm WARN deprecated
npm WARN deprecated   npm -g install npm@latest-2
npm WARN deprecated
npm WARN deprecated To upgrade to the latest stable version, run:
npm WARN deprecated
npm WARN deprecated   npm -g install npm@latest
npm WARN deprecated
npm WARN deprecated (Depending on how Node.js was installed on your system, you
npm WARN deprecated may need to prefix the preceding commands with `sudo`, or if
npm WARN deprecated on Windows, run them from an Administrator prompt.)
npm WARN deprecated
npm WARN deprecated If you're running the version of npm bundled with
npm WARN deprecated Node.js 0.10 LTS, be aware that the next version of 0.10 LTS
npm WARN deprecated will be bundled with a version of npm@2, which has some small
npm WARN deprecated backwards-incompatible changes made to `npm run-script` and
npm WARN deprecated semver behavior.

我尝试查找我也安装了yum的expat-devel，但错误仍然相同。

我还检查了我的python版本，发现它是：

[root@centos fi-ware-pep-proxy]# python -V
Python 2.6.6

有人知道我如何解决这个问题吗？

多亏了@lvaro Alonso，我得出结论，我应该安装gcc：

sudo yum install gcc gcc-c++

如下文所述：

谢谢大家!

Wilma PEP代理未在CentOS中测试。我建议您使用Ubuntu（推荐14.04 LTS）
