我是node新手express

我确实在我的 ubuntu 13.10 机器上安装了节点和 npm。现在，我正在尝试express使用以下命令进行全局安装（我按照官方网站上的说明进行操作）

sudo npm install express -g

但是当我想做的时候

express --help

或者

express

它在外壳中没有任何回报

执行时打印以下日志sudo npm install express -g

你必须跑

npm install -g express-generator

这会下载更多的东西，之后 express 命令应该可以工作。

正如@Nirk 用户所引用的

一些发行版将二进制名称更改为 nodejs，但脚本通常依赖于 node（由于历史原因——在 nodejs 出现之前，node 是一个非常古老的工具

在文件的第一行中进行了以下手动更改/usr/lib/node_modules/express/bin/express。

从

#!/usr/bin/env node

到

#!/usr/bin/env nodejs

现在它对我有用

@Nirk，非常感谢您的支持
