Fix the following localtunnel error "node: No such file or directory"

run npm command gives error "/usr/bin/env: node: No such file or directory" #3911
Some of them already discussed about this issue in git
https://github.com/nodejs/node-v0.x-archive/issues/3911

First we have install npm

sudo apt-get install npm

npm is a Package manager. Installs, publishes and manages node programs.
https://www.npmjs.com/

from the npm add a package localtunnel

sudo npm install -g localtunnel
lt --subdomain=custom --port 80

Sometime the comment give the following error
 "/usr/bin/env: node: No such file or directory"

So you need to install nodejs-legacy dependancy

sudo apt-get install nodejs-legacy

Now, start the localtunnel again

sudo npm install -g localtunnel
lt --subdomain=custom --port 80
