npm install express-generator not installing expre

Question

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

I run this:

npm install -g express-generator

and this is my results:

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)

but when I do

express --ejs flapper-news

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

what am I doing wrong?

Thanks for the time.

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

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

This is my .bashrc file:

### 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

Answer 1

Looking at this line from your output for npm install -g express generator

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

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

Excuse me for an obvious question, but I have to be sure - do you run $ npm install in the directory that contains the package.json file? After you create the app with express --ejs flapper-news, you are supposed to cd flapper-news before npm install, did you?
