mongo couldn't connect to server - mongodb

Question

Even after reinstalling mongo, I face the same problem on my Mac machine. On a fresh reinstall, I keep getting this error, when typing mongo on my Mac terminal.
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect#src/mongo/shell/mongo.js:372:17
#(connect):2:6
exception: connect failed
exiting with code 1
How can I get this problem fixed? Please help.
Also using, mongod on the terminal is throwing this error
