+### Command 'inv' / 'invoke' not found
+
+If the `inv` or `invoke` command does not work, it means that the [invoke](https://pypi.org/project/invoke/) python library has not been correctly installed. 
+
+Update the installed python packages with PIP:
+
+```
+pip3 install -U -r requirements.txt
+```

+Most likely you are trying to run the InvenTree server from outside the context of the virtual environment where the required python libraries are installed.
+
+Always activate the virtual environment before running server commands!
