i've tried several attempts above can see execute npm install command line.

but reason didn't work, i'm guessing it's version error/problem within how os in ubuntu not supported or .json must actual json file in code isn't completed yet? , not javascript error describes itself.

could please me this?

your file invalid, remove last comma in dependencies:

{     "name":"chat",     "version":"0.0.1",     "private":"true",     "dependencies":     {         "socket.io":"1.4.8",         "express":"4.14.0"     } } 

next time use json validator, this, , you'll see what's wrong in file:

error: parse error on line 7: ...ss": "4.14.0",       }    } ----------------------^ expecting 'string', got '}' 

also, looking output, if create directory space, need escape access it, this:

cd chat application/ 

should

cd chat\ application/
