For those who have problems to install like me

it is more easy than you think...

• I uninstall phantomjs: Remove phantomjs from ubuntu sudo apt-get remove phantomjs or remove npm folder of /node_modules/phantomjs it will be in /, maybe you will need to remove ln the link of phantomjs in /usr/bin or /usr/local/bin/ the name of it is phantomjs

Example

//use this if you installed with apt-get
sudo apt-get remove phantomjs    *remove the phantomjs
rm /usr/bin/phantomjs            *use this if the link didn't remove.

//use this if you installed from npm: like this: npm install phantomjs
rm -R /node_modules/phantomjs    *note: it will be in other folder, search it.

• install phantomjs from npm: npm install phantomjs from / directory, npm install it in folder /node_module/phantomjs

Example

cd /;
npm install phantomjs

• Test bin file

Example

//check version of phantomjs
/node_modules/phantomjs/bin/phantomjs -v
/node_modules/phantomjs/bin/phantomjs test.js

• link file bin to /usr/bin:
  

Example

ln -sf /node_modules/phantomjs/bin/phantomjs /usr/bin/phantomjs

• check version of it to see if it's ok
  phantomjs -v in my case 2.1.1
