angularjs - 在 Ubuntu 中启动 Nodejs/Angularjs 应用程序

Question

我刚刚阅读了关于 Angularjs 的教程并想从 http://tinyurl.com/AngularJSDemos 运行测试应用程序(由 (C) Wahlin Consulting 提供) .它的自述文件告知:

NODE.JS OPTION:

If you want to run the site using Node.js (install it from http://nodejs.org) run the following at the command-prompt from within the AngularJSDemos folder:

node server.js

Now navigate to http://localhost:8080/DemoList.html or     http://localhost:8080/CustomerManagementApp in your browser.

我已经安装了 nodejs 并尝试从我的 Ubuntu 系统中的终端启动它:

mainuser@mylaptop:~$ cd /home/mainuser/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos/
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node server.js
The program 'node' can be found in the following packages:
 * node
 * nodejs-legacy
Try: sudo apt-get install <selected package>
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ sudo apt-get install node

...

mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node server.js
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node server.js
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node ./server.js &

mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node ./server.js
[1]+  Exit 1                  node ./server.js
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ node ./server.js
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ sudo apt-get install nodejs

nodejs is already the newest version.
The following packages were automatically installed and are no longer required:
  kde-l10n-engb kde-l10n-pl linux-headers-3.13.0-32
  linux-headers-3.13.0-32-generic
Use 'apt-get autoremove' to remove them.
0 to upgrade, 0 to newly install, 0 to remove and 28 not to upgrade.
mainuser@mylaptop:~/Ebooks/AngularJS/AngularJSDemos/AngularJSDemos$ 

但无论我做什么，我都无法启动这个例子。在 Chrome 中“此网页不可用”和在 Firefox 中“无法连接”。此外，看起来我根本无法在终端中启动它。

如何启动这个例子？

我建议使用 nvm安装node并管理系统上的不同版本。

这很容易:

# First, we need to clone the nvm repository:
$ git clone https://github.com/creationix/nvm.git ~/.nvm

# Then, we need to add the following line to our .profile, .bashrc or .zshrc:
$ echo "source ~/.nvm/nvm.sh" >> .zshrc

安装 nvm 还不够，我们现在需要安装 node & npm。

# To print out the list of all the available versions, simply run:
$ nvm ls-remote

# We want to install the current stable version which is v0.10.26, so we need to run:
The -s flag means we want to compile node from source.
$ nvm install -s v0.10.30

安装过程完成后，将安装我们全新的 Node 和 npm!
nvm 的好处是您可以在每个 shell 实例中使用不同版本的 Node 。但是，如果您想坚持使用最新版本，可以通过运行将其设置为默认值:

$ nvm alias default 0.10.30

通过键入 node -v && npm -v 确保一切正常运行
