找不到Express命令

node.js

由于某些原因,在我的计算机上全局安装Express后,npm install -g express如果我cd进入目录并尝试运行express
,则会收到以下错误:

express: command not found.

即使我运行它,sudo我仍然会得到相同的输出。我已经针对此问题尝试了多种不同的解决方案,但没有任何效果。我已经安装了Node,通过homebrew它表明Stack
Overflow上的某些线程可能是一个问题,所以我完全卸载了Node,然后通过nodejs.org上的安装程序重新安装了该程序(我现在正在运行v0.10.26),问题仍然存在。

如果我进入/usr/local/lib/node_modulesExpress,但在/ usr / local /
bin内,则与Express无关。我不确定这是否是问题,但考虑到该目录中存在其他全局安装的节点程序包的二进制文件,我认为那里可能有问题。

这是我安装时得到的确切输出:

随着Express 4.0.0的发布,您似乎需要这样做sudo npm install -g express-generator
