Question

我是node和express

的新手

我确实在我的ubuntu 13.10机器上安装了节点和npm。现在，我尝试使用以下命令全局安装express（我按照official site上的说明进行操作）

sudo npm install express -g

但是当我想要做的时候

express --help

或

express

它在shell中没有提供任何内容

执行sudo npm install express -g

时打印的日志

我有什么事吗？

更新

我正在使用nodejs版本v0.10.12

Answer 1

你必须运行

npm install -g express-generator

这会下载更多东西，之后应该会有明确的命令。

Answer 2

由@Nirk用户引用

某些发行版将二进制名称更改为nodejs，但脚本经常更改依赖于节点（由于历史原因 - 节点是一个非常古老的工具在nodejs出现之前

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

来自

#!/usr/bin/env node

到

#!/usr/bin/env nodejs

现在它正在为我工作

@Nirk，非常感谢支持人员

（NODEJS）表示全球安装不起作用
