所有这一切都在这里，至少我没有错误。
现在，当我想使用express时，出现问题：

  $ express myapp

回答：

  -bash ：express：command not found

通常，当安装express-generator时会出现此问题，而安装是解决的，但不是我=（如果有人有任何想法我可以做什么，会感谢你。



NodeJS版本：v0.11.13-pre
NPM版本：1.4.6



Ps：所有这些命令我作为根运行



Ps2 ：对不起我的坏英文

解决方案

安装express-generator，我们看到



$ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / $ / b

添加 / var / www / site / npm / bin 到$ PATH

and all good up here, at least I no errors. Now the problem arises when I want to use express:

$ express myapp

It answered:

-bash: express: command not found

Usually this problem occurs when there is express-generator was installed, and the install is solved, but it is not me =(. If anyone has any idea what I can do, will thank you.

NodeJS version: v0.11.13-pre NPM Version: 1.4.6

Ps: All these commands I ran as the root

Ps2: Sorry for my bad english

解决方案

Installing express-generator, we see

/var/www/site/npm/bin/express -> /var/www/site/npm/lib/node_modules/express-generator/bin/express

Add /var/www/site/npm/bin to your $PATH
