npm install express-generator不安装Express [英] npm install express-generator not installing express

问题描述

我正在遵循MEAN堆栈教程，该教程要求我已安装Express:

I'm following a MEAN stack tutorial that requires me to have express installed:

我运行这个:

npm install -g express-generator

这是我的结果:

username@username-Inspiron-3521:~$ npm install -g express-generator
/home/username/npm/bin/express -> /home/username/npm/lib/node_modules/express-generator/bin/express
express-generator@4.13.1 /home/username/npm/lib/node_modules/express-generator
├── sorted-object@1.0.0
├── mkdirp@0.5.1 (minimist@0.0.8)
└── commander@2.7.1 (graceful-readlink@1.0.1)

但是当我这样做

express --ejs flapper-news

The program 'express' is currently not installed. You can install it by typing:
sudo apt-get install node-express

我在做什么错了?

感谢您的时间.

修改

当我做npm install

username@username-Inspiron-3521:~/Documents/mean/flapper_news$ npm install

edit2

运行npm install -g express并键入express -v后，我得到了:

after running npm install -g express and typing express -v I get this:

bash: /usr/bin/express: No such file or directory

edit3

这是我的.bashrc文件:

### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
export PATH=$HOME/local/bin:$PATH
export NODE_PATH=/usr/lib/nodejs:/usr/lib/node_modules:/usr/share/javascript:/home/username/npm/lib/node_modules
export PATH=/home/username/Android/Sdk/platform-tools:$PATH
export PATH=/home/username/Android/Sdk/tools:$PATH

推荐答案

在输出中的npm install -g express generator

/home/username/npm/bin/express -> /home/username/npm/lib/node_modules/express-generator/bin/express

您的npm在主目录中安装全局模块，并将二进制链接放置在/home/username/npm/bin目录中，因此您需要将其添加到路径中.将此添加到您的.bashrc:

Your npm is installing global modules within your home directory and it's placing binary links in the /home/username/npm/bin directory, so you'll need to add this to your path. Add this to your .bashrc:

export PATH=$HOME/npm/bin:$PATH
