# ❗️ Common Installation Issues
|
|
|
|
This is a list of possible issues that you may encounter when installing Langflow 1.0 alpha and how to solve them.
|
|
|
|
## _`No module named 'langflow.__main__'`_
|
|
|
|
1. Run _`python -m langflow run`_ instead of _`langflow run`_.
|
|
2. If that doesn't work, reinstall Langflow with _`_python -m pip install langflow --pre -U`_.
|
|
3. If that doesn't work, reinstall Langflow and its dependencies with _`python -m pip install langflow --pre -U --force-reinstall`_.
|
|
|
|
When you try to run Langflow using the command `langflow run`, you may encounter the following error:
|
|
|
|
```bash
|
|
> langflow run
|
|
Traceback (most recent call last):
|
|
File ".../langflow", line 5, in <module>
|
|
from langflow.__main__ import main
|
|
ModuleNotFoundError: No module named 'langflow.__main__'
|
|
```
|
|
|
|
There are two possible reasons for this error:
|
|
|
|
1. You've installed Langflow using _`pip install langflow`_ but you already had a previous version of Langflow installed in your system.
|
|
In this case, you might be running the wrong executable.
|
|
To solve this issue, run the correct executable by running _`python -m langflow run`_ instead of _`langflow run`_.
|
|
If that doesn't work, try uninstalling and reinstalling Langflow with _`python -m pip install langflow --pre -U`_.
|
|
2. Some version conflicts might have occurred during the installation process.
|
|
Run _`python -m pip install langflow --pre -U --force-reinstall`_ to reinstall Langflow and its dependencies.
|
|
|
|
## _`Something went wrong running migrations. Please, run 'langflow migration --fix'`_
|
|
|
|
Clear the cache by deleting the contents of the cache folder.
|
|
|
|
This folder can be found at:
|
|
|
|
- **Linux or WSL2 on Windows**: `home/<username>/.cache/langflow/`
|
|
- **MacOS**: `/Users/<username>/Library/Caches/langflow/`
|
|
|
|
This error can occur during Langflow upgrades when the new version can't override `langflow-pre.db` in `.cache/langflow/`. Clearing the cache removes this file but will also erase your settings.
|
|
|
|
If you wish to retain your files, back them up before clearing the folder.
