找不到快速命令

Question

出于某种原因,在我的机器上全局安装Express之后,npm install -g express如果我cd进入目录并尝试运行express,我会收到以下错误:

express: command not found. 

即使我运行它sudo仍然得到相同的输出.我已经尝试了多种不同的解决方案来解决这个问题.我已经安装了节点homebrew,Stack Overflow上的某些线程可能是一个问题所以我完全卸载了节点并通过nodejs.org上的安装程序重新安装(我现在正在运行v0.10.26)并且问题仍然存在.

如果我进入我的/usr/local/lib/node_modulesExpress就在那里但是在/ usr/local/bin中没有任何关于Express的信息.我不确定这是否是一个问题,但考虑到该目录中有其他全局安装的节点包的二进制文件,我认为可能存在问题.

这是我安装时获得的确切输出:

Answer 1

随着Express 4.0.0的发布,它看起来像你需要做的sudo npm install -g express-generator.

Answer 2

你需要运行:

npm install -gd express-generator

原来用cli表达,现在将cli分成单独的快速发生器包.最初由项目生成的是运行快递节点app.js,因为httpserver相关代码在app.js中,现在这部分代码到了项目目录bin/www下面,app.js只保留了实现app逻辑代码,需要运行bin/www.只是一个非常简单的应用程序和优化包依赖版本更改.
