node.js and express -bash: /usr/bin/express: No such file or directory

Question

I started a Digital Ocean droplet from the node.js image ( w ubuntu 14.04) checking it, I get :

$ node -v
  v4.3.0

Then , I tried to install the latest version of express.js :

    $ sudo npm install -g express
    express@4.13.4 /usr/lib/node_modules/express
    ├── escape-html@1.0.3
    ├── array-flatten@1.1.1

    └── accepts@1.2.13 (negotiator@0.5.3, mime-types@2.1.10)

but when I check express version , I get an error :

  $ express -v
 -bash: /usr/bin/express: No such file or directory

what could be wrong ? thanks for feedback

UPDATE ---

I uninstalled& reinstalled node.js :

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodes
$ node -v
v4.3.1

but same issue

sudo npm install -g express express@4.13.4 /usr/lib/node_modules/express ... $ express -v -bash: /usr/bin/express: No such file or directory

Answer 1

Check that /usr/lib/node_modules/express is present in your PATH variable.

echo $PATH will print current PATH

Also, maybe you dint install express-generator?
