Running the program gets a blank page

pip install langflow

get error: Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.
I use python3.9 and I've tried versions 0.6.4, 0.2.0, 0.0.78 all with blank pages

Hey @ruan-xb-63! Good to see you again. Looks like you've run into a new challenge! Let's find a way through this one together. 😄

The error message you're seeing, "Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.", is typically due to the server not serving the JavaScript files with the correct MIME type.

This could be due to a misconfiguration in the server or a problem with the build process of the JavaScript files.

As for the blank page issue, it could be related to the above error or it could be a separate issue. It's hard to tell without more information.

Could you please provide the following additional information to help diagnose the issue:

1. The exact command you're using to start the server.
2. Any additional error messages in the console.
3. The network tab of the browser's developer tools when you load the page. This can show if any resources are failing to load which could cause a blank page.

Also, please ensure that all the dependencies listed in the pyproject.toml file are correctly installed. You can check this by running the project and checking if there are any errors related to missing or incorrect versions of dependencies.

If you're still facing the issue, it would be helpful if you could provide a minimal reproducible example. This would involve the smallest amount of code and steps necessary to reproduce the issue. This can help in identifying the exact cause of the problem.

Looking forward to your response.

Best,
Dosu
