使用 node.js 安装高速公路

Question

我是 nodejs 的新手，正在寻找运行 Ubuntu 16.04 上的一些简单代码。

我已经安装了nodejs和npm

root@coding:~# node -v
v6.3.0
root@coding:~# npm -v
3.10.3

我现在正在按照以下方式安装高速公路： http://autobahn.ws/js/gettingstarted.html

不幸的是我得到：

root@coding:~# npm install autobahn

> node-gyp rebuild

Answer 1

警告-1：

gyp WARN download NVM_NODEJS_ORG_MIRROR is deprecated and will be removed in node-gyp v4, please use NODEJS_ORG_MIRROR

原因： 您的 npm 或高速公路的依赖项之一正在使用已弃用的库或函数，在本例中为 NVM_NODEJS_ORG_MIRROR。如果您的 npm 已经是最新的，请不要担心 autobahn 的人会修复它。如果您觉得有问题，请向他们提出问题。

警告-2：

npm WARN enoent ENOENT: no such file or directory, open '/root/package.json'
npm WARN root No description
npm WARN root No repository field.
npm WARN root No README data
npm WARN root No license field.

原因： 您没有 package.json。只需运行 npm init 并按照说明进行操作，它就会为您创建一个。

结论：

无论哪种方式都是警告。检查您的 node_modules\ 文件夹，很可能一切都应该安装，因为没有列出任何错误。
