fiware - 我的 PeP 代理安装中缺少什么？

Question

我正在关注this tutorial安装 PeP 代理。

我在 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.

我尝试寻找 expat-devel，我也安装了它，但错误仍然存​​在。

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

有人知道如何解决这个问题吗？

感谢@Álvaro Alonso，我得出的结论是我应该安装 gcc:

sudo yum install gcc gcc-c++

如下所述:
