I flagged this answer https://stackoverflow.com/a/16198105/731947 as not an answer.
got the same error, in Windows running with Administrator privileges solved the problem.
And got this resolution:
declined - flags should not be used to indicate technical inaccuracies, or an altogether wrong answer
Also read this answer: https://meta.stackexchange.com/a/114606/161180
So let's break it down:
got the same error
Sort of "I am having the same problem,"
got the same error,in Windows ...
... the file to mongodb to the directory usr/local/mongodb.
and OP's first line from the code block:
./bin/mongod --help for help and startup options
SO the 'answer' is basically saying: "don't care what you have there, just use Windows and run it with admin privileges, that's what I did"
I get it could be declined because it has a few more words there except "got the same error" but just read the question and you see it's Out Of Topic, useless and doesn't solve the problem. I don't understand how that answer could help future visitors or anybody else on that matter... prove me wrong if you must
