The mongodb installation encounters difficulties. How to uninstall and reinstall?

Question

1. Install mongodb through the online installation method, then execute brew update, and then execute brew install mongodb; an error is reported at this time:

   Error: You must `brew link makedepend` before mongodb can be installed
   

2. When directly searching for the mongodb shell, the following error is reported:

MongoDB shell version v3.4.2
connecting to: mongodb://127.0.0.1:27017
2017-04-18T18:51:28.415+0800 W NETWORK  [thread1] Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: Connection refused

3. Dear friends, how should I uninstall and then reinstall? Or how can I solve the above problem without uninstalling it? Do you guys have any better installation tutorials? My computer is a Mac system. Please provide me with a link and guidance~~~ I’m very grateful

Answer 1

Just run this

Reinstall after running

brew link makedepend

Isn’t it good to install docker? ?

No thanks GG
