## Frequently Asked Questions
|
|
|
|
### Errors during InvenTree update
|
|
|
|
Sometimes, users may encounter unexpected error messages when updating their InvenTree installation to a newer version.
|
|
|
|
The most common problem here is that the correct sequenct of steps has not been followed:
|
|
|
|
1. Ensure that the InvenTree web server and background worker processes are *halted*
|
|
1. Update the InvenTree software (e.g. using git or docker, depending on installation method)
|
|
1. Run the `invoke update` command
|
|
1. Restart the web server and background worker processes
|
|
|
|
For more information, refer to the installation guides:
|
|
|
|
- [Docker Installation](./start/docker_prod.md#updating-inventree)
|
|
- [Bare Metal Installation](./start/install.md#updating-inventree)
|
|
|
|
!!! warning "Invoke Update"
|
|
You must ensure that the `invoke update` command is perfomed *every time* you update InvenTree
|
|
|
|
### Feature *x* is not visible after update
|
|
|
|
If a particular menu / item is not visible after updating InvenTree, it may be due to your internet browser caching old versions of CSS and JavaScript files.
|
|
|
|
Before [raising an issue](https://github.com/inventree/inventree/issues), try hard-refreshing the browser cache:
|
|
|
|
<kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>R</kbd>
|
|
|
|
or
|
|
|
|
<kbd>Ctrl</kbd> + <kbd>F5</kbd>
|
|
|
|
### Problems Installing on Windows
|
|
|
|
InvenTree installation is not officially supported natively on Windows. Install using the WSL framework.
|
|
|
|
### 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
|
|
```
|
|
|
|
### ModuleNotFoundError: No module named 'django'
|
|
|
|
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!
|
|
|
|
### Background Worker "Not Running"
|
|
|
|
The background worker process must be started separately to the web-server application.
|
|
|
|
From the top-level source directory, run the following command from a separate terminal, while the server is already running:
|
|
|
|
```
|
|
invoke worker
|
|
```
|
|
|
|
!!! info "Supervisor"
|
|
A better option is to manage the background worker process using a process manager such as supervisor. Refer to the [production server guide](./start/production.md).
