找不到快速命令 [英] Express command not found

问题描述

出于某种原因，在我的机器上使用 npm install -g express 全局安装 Express 后，如果我 cd 进入一个目录并尝试运行 express，我收到以下错误:

express:未找到命令.

即使我用 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 安装了节点，Stack Overflow 上的一些线程表明可能有问题，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(我现在运行的是 v0.10.26)和问题仍然存在.

如果我进入我的 /usr/local/lib/node_modules Express 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节点包的二进制文件，我认为那里可能有问题.

这是我安装时得到的确切输出:

解决方案

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

For some reason after installing Express globally on my machine with npm install -g express if I cd into a directory and try to run express I get the following error:

express: command not found. 

Even if I run it with sudo I still get the same output. I've tried multiple different solutions to this problem and nothing has worked. I had installed node via homebrew which some threads on Stack Overflow indicated might have been a problem so I completely uninstalled node and reinstalled via the installer on nodejs.org (I'm now running v0.10.26) and the problem still persists.

If I go into my /usr/local/lib/node_modules Express is in there but within /usr/local/bin there is nothing regarding Express. I'm not sure if that's a problem or not but considering there are binaries for other globally installed node packages in that directory I'm thinking there may be something wrong there.

This is the exact output I get when I install:

With the release of Express 4.0.0 it looks like you need to do sudo npm install -g express-generator.
