I'm trying to setup a cronjob for a regularly scheduled import of json data into a mongo database. To conduct the import, I have the following command in the Python script that the cronjob runs:
os.system("mongoimport --jsonArray --db %s --collection %s --file .../data.txt" %(db_name,collection_name))
However, the log file of the cronjob keeps displaying the following error:
sh: mongoimport: command not found
I think I need to call mongoimport with the full file path in the code, but I'm not sure where mongodb/mongod/mongoimport is installed on my system. whereis mongoimport, whereis mongodb, whereis mongod all return nothing.
I installed mongodb with Homebrew. Packages installed with Homebrew are located in /Library/Caches/Homebrew. However, in my system that folder only has a mongodb-2.6.4_1 tar file. Do I have to unpack this tar file to access mongoimport?
Thanks for your help.
As of June 2020,
I installed mongodb latest version using brew as per the documentation , and I faced the same issue command not found: mongoimport .
I had to to install mongodb-database-tools
brew install mongodb/brew/mongodb-database-tools
Then I could use mongoimport
Just adding this solution, incase it helps someone
Got the same issue, but I installed mongodb via Mac Port. Unfortunately, from version 3 of mongodb, these mongodb tools are maintained as a separate project, so I updated Mac port to latest version then installed mongo tools separately.
sudo port install mongo-tools
Hope this helps someone that installing mongodb by mac port.
If you installed MongoDB correctly you need to create a ~/.bash_profile and assign /usr/local/mongodb/bin to the $PATH environment variable
After that you should be able to access the mongoimport command
If you used brew for installation, mongod is in /usr/local/bin/ directory. Other utilities (mongoimport, mongoexport etc.) are in the same path. All you need to do is open another terminal.
Visit https://www.mongodb.com/download-center/community and you can download a tarball for MacOS, which contains all the tools including mongoimport.
Untar, add to you PATH and voilà!
Try using ./mongoimport or sudo ./mongoimport
After following all of these examples, I was able to use it that way from bash.
I am trying to test MongoDB and I have it all downloaded and moved into the root folder. I can navigate to the folder that holds the mongod, but when I try to run it by typing "mongod" into my terminal, I get a message that says:
"mongod: command not found"
Both answers above are correct.
You can either specify the path in one of the following files: .profile, .bashrc, or .bash_profile
export PATH="$PATH:/usr/local/mongodb/bin"
then call the daemon or the shell directly
mongod
mongo
Or for the commands not in the $PATH, use ./mongo or ./mongod from the directory containing these files. This solution can be verbose has you will have to eventually append the whole path when calling these commands from another directory.
/usr/local/mongodb/bin/mongod
or
/usr/local/mongodb/bin$ ./mongod
"Mongod" isn't a stand-alone command. You need to run the command like this:
./mongodb/bin/mongod
I used this webpage to help me answer this question.
This worked for me:
brew tap mongodb/brew
brew install mongodb-community#4.2
mongod
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/
For example, install 64bit MongoDB 2.6.12 on macOS Catalina.
(for newest versions you may go to https://www.mongodb.com/download-center/community for your platform).
Download, extract and move:
wget http://downloads.mongodb.org/osx/mongodb-osx-x86_64-2.6.12.tgz
tar xzf mongodb-osx-x86_64-2.6.12.tgz
mv mongodb-osx-x86_64-2.6.12/ /usr/local/mongodb/
Add to file ~/.zshrc this:
export PATH="$PATH:/usr/local/mongodb/bin"
PS: .bash_profile or .profile not worked in my case
Reload terminal (or close, open it):
source ~/.zshrc
Make directory for data and set rights:
mkdir -p ~/data/db
chown -R mongodb.mongodb ~/data/db
Run MongoDB:
mongod --dbpath ~/data/db
You need to add the name of the folder that contains the command mongod into your PATH so your shell knows where to find it.
So, if mongod is in /usr/bin/freddyfrog, you would edit ~/.profile and find the line that says PATH= and edit it to look like this:
export PATH=${PATH}:/usr/bin/freddyfrog
Then login again to make it take effect.
I received the same error message because I used the wrong command to run mongod (meant for M1s) for my 2019 MacBook with an Intel processor. You can skip past Homebrew updates and MongoDB installation but here's how I resolved my issue:
Download Xcode Command Line tools.
xcode-select --install
Allow Homebrew to add and access MongoDB:
brew tap mongodb/brew
Update Homebrew:
brew update
Install MongoDB Community Edition (#6.0 is the latest version at the time of this post):
brew install mongodb-community#6.0
macOS with Intel processors:
mongod --config /usr/local/etc/mongod.conf --fork
macOS with Apple M1 processors:
mongod --config /opt/homebrew/etc/mongod.conf --fork
Then open the shell:
mongosh
Or just run mongod.
Official documentation on installation here.
3 steps:
Step 1:
export PATH="$PATH:/usr/local/mongodb/bin"
OR
export PATH="$PATH:/usr/local/opt/mongodb#3.2/bin"
(replace version number with your local version)
The first step will allow you to run the command, but will get you another error: "/data/db does not exit" so you have to
Step 2 :
sudo mkdir -p /data/db
Now /data/db is read only, but it has to be writable also so
Step 3 :
sudo chown -R USERNAME /data/db
I was trying to install a previous version (3.6) using latest documentation (4.2 is already released). So, they now call it mongodb-community#3.6.
In order to update PATH for such setup, the statement should be
export PATH="$PATH:/usr/local/opt/mongodb-community#3.6/bin";
I got hint from #retroGiant 's answer
run this command, it works:
brew services start mongodb-community#4.0
I have installed mongodb-community#3.2, was facing the same issue. I followed below steps.
open bash profile in any editor (you can also try - vi ~/.bash_profile)
write this export PATH="$PATH:/usr/local/opt/mongodb-community#3.2/bin" & save.
do this . source ~/.bash_profile
In root directory
sudo mkdir data
cd data
mkdir db
then
sudo chown -R yourUsername /data/
copy path of your mongodb/bin downloaded folder (I suggest you put it in home folder not root dir)
in terminal
export PATH="paste the link here :$PATH"
now it should work but if not
In case you are using different Unix shell and
trying to execute mongod within visual studio code( for example ),
make sure to read the documentation to link PATH.
For example, if you are using zsh create .zprofile in your home directory.
touch .zprofile
copy your previously made PATH into .zprofile
Now everything should work as expected.
I was looking for the same and later I have found that now it's very straight forward to install the new MongoDB Community Edition like below:
Installing MongoDB 6.0 Community Edition
brew tap mongodb/brew
Note: If you haven't yet install brew then follow this link: https://brew.sh/#install
Update Homebrew
brew update
Install MongoDB
brew install mongodb-community#6.0
The installation includes the following binaries:
The mongod server
The mongos sharded cluster query router
The MongoDB Shell, mongosh
Run MongoDB Community Edition
To run MongoDB (i.e. the mongod process) as a macOS service, run:
brew services start mongodb-community#6.0
To stop a mongod running as a macOS service, use the following command as needed:
brew services stop mongodb-community#6.0
MongoDB 5.0 issue resolved - SEP/2022
do following steps
step 1: open a .zshrc file if it does not exist it will create by itself by following the command. For opening or creating a .zshrc file below command is the same.
vim .zshrc
step 2: insert value in it by pressing 'i'
step 3: insert the below command there or paste it there.
export PATH="$PATH:/usr/local/opt/mongodb-community#5.0/bin"
step 4: to exit click on esc key and the write :wq
step 5: Close the terminal and reopen it and type the below command
mongo
Output
MongoDB shell version v5.0.11
connecting to: mongodb://127.0.0.1:279021/?
compressors=disabled&gssapiServiceName=mongodb
Successfully integrated mongo 🎉 🎉 🎉
happy coding !!
If you use brew then check the path:
brew list
brew list mongodb-community#...
then add it to .zshrc
zsh: command not found: mongo
after that use mongosh instead of mongo
This answer is a little bit unrelated, but if you using vscode & would like to interact with mongoDB using command line, have a read.
I was looking to use mongod command as well (as i love to use command to interact with mongoDB), but after several attempts of install i completely give up. Until i found this, the mongoDB vscode extension.
The extension is loading the data pretty fast just like mongod command compare to mongo compass. It allow you to perform CRUD & aggregation in the mongoDB playground, and most importantly you able to retrieve the command on next execution by storing your command in a file with .mongodb extension.
*Update: After using it several weeks, everything is nice, just need to make sure you connecting to the right mongoDB connection (if you establish few different connection)
I've installed Postgres93 on my Mac. I can open the application, and "Open psql" through the app which opens up a command line interface with psql.
However, when I type $ which psql nothing is returned. The installation path is /Applications/Postgres93.app. How do I make $ which psql show the correct result?
Mac OS X - Mavericks
PostgreSQL package, I'm not as sure about. I went here and downloaded it - http://postgresapp.com/
I just had postgres installed and was not able to run the psql command until I ran the following command in my terminal:
export PATH="/Applications/Postgres.app/Contents/Versions/9.5/bin:$PATH"
Now the terminal knows where to find postgres when I use the psql command.
Remember to replace the version number '9.5' with your current version.
I had the same problem with nothing showing for the which psql command till I run the command below to resolve it. The command provided below is just a little tweak of what has already been provided by others here. The only difference is, instead of providing a specific postgres version number in the command, you can simply tell postgres to use the latest postgres version by simply running the following command:
export
PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"
And now my terminal was able to find the path to postgres when I run which psql.
Hope this helps.
On macOS Mojave these instructions work well:
If your Postgres has not been installed yet, I suggest you use the great "brew" package manager from here https://brew.sh/ :
$ brew cask install postgres
or you can install it usual way from the website
Put this to the bottom of your ~/.bash_profile file:
export PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:${PATH}"
Restart your terminal or restart your ~/.bash_profile directly with the command:
$ . ~/.bash_profile
Verify your installation:
$ psql --version
** Edited: to include a permanent fix, not just during your current session. **
I had this same problem, and also found a clear answer lacking in the docs.
To fix:
Download the new app, and follow the instructions to move it to the Applications folder
Add the new bundle to your path by typing the following in your Terminal (version number specific - mine is 9.4):
PATH="/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH"
To fix the issue on a permanent basis, run the same line but with export in front:
export PATH="/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH"
It appears that you installed Heroku's Postgres.app, which is a tool intended for throw-away testing and development. Add the contents of the bundle to your PATH by following the instructions in the Postgres.app documentation - see "command line tools".
On macos mojave i've added the following line on my ~/.profile :
export PATH=$PATH:/Library/PostgreSQL/10/bin
the psql command line client lies into this folder. i've used the enterprisedb installer.
I just experienced the same problem, and solved it by adding export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin to .bash_profile. Note that this line is version-specific, so be sure to check this line against your current version of Postgres.app.
Using Mac OS Monterey, the latest Homebrew (3.4.0) and postgres#13.
I was able to add psql to the path by using -
export PATH="/opt/homebrew/Cellar/postgresql#13/13.6/bin:$PATH"
Replace #13 and 13.6 with your version.
The latest homebrew install location seems to be /opt/homebrew/*
I'm using catalina 10.15.3 and I had the same issue after installing psql using homebrew. Then I noticed, homebrew mentioned
==> libpq
libpq is keg-only, which means it was not symlinked into /usr/local,
because conflicts with postgres formula.
If you need to have libpq first in your PATH run:
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.bash_profile
So, I ran 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.bash_profile and psql was added to my path
In Mac, there is a SQL Shell application already under /Applications/PostgresSQL
try that
Also, you can run /Library/PostgreSQL/11/scripts/runpsql.sh
In my case, I installed Postgres12 and had the same issue. I had to look out for the location of my bin folder. It happened to be in /Applications/2ndQuadrant/PostgreSQL/12/bin. So I had to run export PATH="/Applications/2ndQuadrant/PostgreSQL/12/bin:$PATH" in my terminal and restart the terminal. That solved it.
I'm trying to get a dump of my local database and it seems I should be using:
mongodump --host localhost:3002
However, the terminal then tells me:
-bash: mongodump: command not found
Am I missing something? Or going about this the wrong way? I'm using it on Mac from the terminal.
I installed mongo (I think) using the following commands:
curl http://downloads.mongodb.org/osx/mongodb-osx-x86_64-2.4.5.tgz > mongodb.tgz
tar -zxvf mongodb.tgz
As of MongoDB 4.4 (released July 30, 2020), you may need to install mongodump separately because the MongoDB Database Tools (which comprises mongodump, mongorestore, and more) has become its own project.
I found this out because I upgraded to MongoDB 4.4 today and mongodump stopped working.
$ mongodump
zsh: command not found: mongodump
I'm on macOS and installed MongoDB via Homebrew. To get mongodump and friends back, I installed the MongoDB Database Tools via Homebrew:
brew tap mongodb/brew
brew install mongodb-database-tools
If you're on a different OS, this should help:
MongoDB Database Tools Installation
brew tap mongodb/brew; brew install mongodb-community
will also install mongodump.
If you don't have the brew command, you really should consider install Homebrew
If you just extracted the .tgz file, the mongodump command is not available in your PATH. Go to your /bin/ subdirectory inside the directory where you have extracted mongodb.tgz, the mongodump binary should be there. Now you can execute:
./mongodump --host localhost:3002
It's much better though to install MongoDB with a package manager. Read this page:
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/
and use, for example, Homebrew to install MongoDB and have all the necessary binaries in PATH.
brew tap mongodb/brew
brew install mongodb-database-tools
For using mongodump, mongo-tools library has to be installed from os package manager.
It's probably just not in your path, it should be in the same directory as your "mongod", and you can then run it with:
/path/to/bin/mongodump --host localhost:3002
It's in the official MongoDB docs now. For example, to install the 3.2 version:
brew tap mongodb/brew
brew install mongodb-community#3.2
Then follow the steps to update your PATH environment variable.
You have to install mongo-tools to have mongodump.
sudo apt-get install mongo-tools
For Windows Users
You can download the MongoDB Database Tools from here
And you can read the installation guide here
I installed MongoDB via Homebrew (following http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/) but it's not working.
Typing mongod at shell prompt gives me:
-bash: mongod: command not found
Not sure if I need to add something for Homebrew to my PATH env var?
I can see Mongo is installed under /usr/local/Cellar/mongodb – but am assuming I don't need to add everything I install via homebrew to the path? Also, assuming I can run mongod from any directory or am I actually meant to be in install directory?
When I run brew doctor I get:
Warning: You have unlinked kegs in your Cellar
Followed by a list of 3 items which includes MongoDB – but I'm not sure how I'm meant to link them?
Works perfectly
brew update
brew tap mongodb/brew
brew install mongodb-community#4.2
For latest version, check https://docs.mongodb.com/manual/release-notes/
You're getting this error because your 'brew' install failed to create the correct symlinks in /usr/local/bin. As a result, the shell can't find the mongo executables in your $PATH. You can fix this using the following steps:
Check the permissions on /usr/local/bin and make sure that you own that directory and have write permissions on it
$ ls -ld /usr/local/bin
Once you've fixed that, run 'brew link' to fix the symlinks
$ brew link mongodb
If you are on mongodb-community#4.0. You can try to reinstall with brew reinstall mongodb-community#4.0.
Then I get the following hint:
==> Caveats
mongodb-community#4.0 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have mongodb-community#4.0 first in your PATH run:
echo 'export PATH="/usr/local/opt/mongodb-community#4.0/bin:$PATH"' >> ~/.bash_profile
So you can just copy the echo command and restart your shell!
Copied from a different channel running these commands in the terminal updated the installation/configuration issues as described in OP
brew tap mongodb/brew
brew install mongodb-community
brew services start mongodb-community
I faced the same problem and this solution seemed to work for me. I had previously uninstalled mongodb and reinstalled it through homebrew which gave me a bunch of problems. This solution seemed to work just fine.
brew uninstall --force mongodb
brew cleanup -s mongodb
brew cleanup --prune-prefix
brew install mongodb
It works from the directory since the sh searches the ENV path and then the cwd for a program named mongod. I have been looking around a little and it seems that the default install of MongoDB (I am not a Mac user) does not install a rc or init script for which sh to understand it's running behaviour as stated here:
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/#using-mongodb-from-homebrew-and-macports
The packages installed with Homebrew and MacPorts contain no control
scripts or interaction with the system’s process manager.
If you have configured Homebrew and MacPorts correctly, including
setting your PATH, the MongoDB applications and utilities will be
accessible from the system shell. Start the mongod process in a
terminal (for testing or development) or using a process management
tool.
So you must actually define (as you said) MongoDBs path, here is an example: https://snipt.net/sido/installing-mongodb-on-os-x/
Edit: the example is not mine. I just stole it from it's user: https://snipt.net/sido/
