node.js - 找不到快速命令

Question

由于某种原因，使用 npm install -g express 在我的机器上全局安装 Express 后，如果我将 cd 放入目录并尝试运行 express，我收到以下错误:

express: command not found. 

即使我使用 sudo 运行它，我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，但没有任何效果。我已经通过 homebrew 安装了 Node ，Stack Overflow 上的一些线程表明这可能是一个问题，所以我完全卸载了 Node 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)和问题仍然存在。

如果我进入我的 /usr/local/lib/node_modules Express 就在那里，但在/usr/local/bin 中没有关于 Express 的任何内容。我不确定这是否有问题，但考虑到该目录中有其他全局安装的 Node 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:

Answer 1

随着 Express 4.0.0 的发布，您似乎需要执行 sudo npm install -g express-generator。
