无法使用 mongo 命令，在 mac 上显示找不到命令

Question

I'm using Mac Lion. I was using mongodb version 1.4. I wanted to upgrade to 1.8.5 and I followed http://shiftcommathree.com/articles/how-to-install-mongodb-on-os-x step wise replacing each mongodb-osx-x86_64-1.4.0 by mongodb-osx-x86_64-1.8.5. Everything goes smooth. I tried:

mongod 

it's ok. I can access localhost:28017 but,

mongo

shows command not found

How can I fix this?

Answer 1

You need to add the path to "mongo" to your terminal shell.

export PATH=$PATH:/usr/local/mongodb/bin

Did you do the last step with paths.d? If so, try restarting your terminals.

Do you have a good reason for using 1.8.5? The current stable is 2.0.4, and it has many useful upgrades from 1.8.x

Answer 2

Starting from Mongodb version 6.0 mongo was replaced by mongosh

Answer 3

For readers in 2021:

export PATH="$PATH:/usr/local/opt/mongodb-community@3.6/bin"

Answer 4

You'll have to add the location of the Mongo binary to PATH.

Follow the steps below in order to make the PATH variable permanent:

1. Open Terminal and navigate to your user directory.
2. Run touch ~/.bash_profile and then open ~/.bash_profile .
3. In TextEdit, add export PATH="<mongo-directory>/bin:$PATH" (Keep the quote marks - related to white spaces).
4. Save the .bash_profile file and Quit (Command + Q) Text Edit.
5. Run source ~/.bash_profile .
6. Run echo $PATH and check if the you see that the Mongo binary was added.

(*) Notice that the PATH variable is now available only for the current terminal and not to processes that were already started in the session.
In order to make it available outside the current terminal - you'll have to logout and login.

Answer 9

I didn't have the right mongo command line tools installed. This from Brew worked for me though.

brew install mongodb-community

Answer 10

In Mac:

Go into Bash Profile:

vi ~/.bash_profile

Add Path of Installation of MongoDB:

export PATH=$PATH:/usr/local/opt/mongodb-community@4.2/bin

Reload the Bash Profile:

source ~/.bash_profile

Answer 11

just a little recommandation, if your path has a space just wrap the whole path with quote or doublequote example : C:\Program Files\MongoDB\Server\4.2 . notice the space in "Program Files"

export PATH=$PATH:"C:/Program Files/MongoDB/Server/X.X/bin"

Answer 12

in place of mongo command use mongosh command and it will work.
