Can someone tell me how to fix it ? or how to install mongodb correctly?

Answer 1

When you typed in the mongod command, did you also give it a path? This is usually the issue. You don't have to bother with the conf file. simply type
mongod --dbpath="put your path to where you want it to save the working area for your database here!! without these silly quotations marks I may also add!"
example: mongod --dbpath=C:/Users/Kyle-3/Desktop/DEV/dangerzonearea/test/mongodb
That is my path and don't forget if on windows to flip the slashes forward if you copied it from the or it won't work!
