crontab: Command not found when running Python script

Question

I wrote a Python script which backs up mongoDB, and it works fine when I test run directly in terminal.

However, I get an error from cron saying mongodump: command not found - although the command mongodump works fine when I run the script directly in terminal.

Contents of crontab -e:

* * * * * cd <path-to-script> && python3 script.py

Answer 1

After looking into the post provided by S3DEV's.

Running the full env path of mongodump into the python script worked. To get the full path of mongodump, in terminal:

which mongodump
>>/usr/local/bin/mongodump

In my case i am using os.system() in my script.

os.system(/usr/local/bin/mongodump [commands])

instead of

os.system(mongodump [commands])
