前preSS命令在bash未发现NPM安装后 [英] express command not found in bash after installing it with npm

问题描述

刚刚安装了Ubuntu的新虚拟机测试不同节点
按照此顺序安装的东西：

just installed new ubuntu vm to test around with node installed things in this order:

node
mongodb-server
npm
express
mongoose

现在，试图创建一个新的应用程序，我注意到前preSS不能在外壳中使用。
前preSS -v 收益
前preSS：找不到命令

now, trying to create a new app i noticed express cannot be used in the shell. express -v returns express: command not found

我安装NPM这样

curl http://npmjs.org/install.sh | sudo sh

和我安装前preSS这样

and i installed express this way

npm install express

什么想法？

推荐答案

NPM安装前preSS -g

您需要在全球范围内安装它。

You need to install it globally.

NPM 1.0在默认情况下在本地安装的模块。所以在bash可执行住在 / node_modules /斌/ 。你可以将该文件夹添加到 PATH ，也可以只安装前preSS 全局，这样它是由回升 PATH

Npm 1.0 installs modules locally by default. So the bash executable lives in /node_modules/bin/. You can add that folder to PATH or you can just install express globally so that it's picked up by PATH
