An Error Occurs While Running 'backend'

[wdEffort]

After navigating to the 'backend' directory and using poetry to run the application, the following message is displayed:

Could you please help me resolve this issue?

Seems like the issue is with the moviepy (and imageio) install on your machine.

ChatGPT has a suggestion that's worth trying out: https://chatgpt.com/share/8f4f8836-8c1d-4275-9135-47db33e17936

Let me know if it fixes it.

@abi
Thank you for your reply.

By referring to the solution provided, I was able to run 'backend' normally (see image below).

In addition, node.js, npm, and yarn were additionally installed through 'nvm' installation on the server in the RedHat 9.4 OS environment, and 'frontend' was run normally.

However, I have four additional questions as listed below.

1. Can I specify a port when running ‘Backend’ and ‘Frontend’?
   • For example, 'backend' is '7002' and 'frontend' is '80'.
2. Is there a way to connect to the Apache web server?
3. Can I ignore the warning message below when using the 'poetry install' command?

   WARNING: The current project cannot be installed. File/folder not found for package backend.
   Use --no-root if you do not want to install the current project.
   If you want to use Poetry only for dependency management and not for packaging, you can disable package mode by setting package-mode = false in your pyproject.toml file.
   This warning will be an error in future versions of Poetry!

4. What does the ERROR phrase below ‘when running frontend’ mean?

   ERROR
   [TypeScript] Found 0 errors. Watching for file changes.

Is the app working for you? Are you able to put in a screenshot and generate some code?

1. Yes, you can pass in CLI arguments or modify the code to update the ports
2. Not sure what you mean. @Jonathan-Adly wrote up some instructions on hosting this yourself: https://jonathanadly.com/securing-your-self-hosted-open-source-ai-application
3. Yes, you can ignore this warning.
4. You can ignore this as well.

@abi Thank you for your reply.

Currently, the app is running normally and can be accessed and used externally.

To resolve the above issue, I followed these steps:

1. Run the 'backend'

   • I used the 'poetry run' command on the server.
     • Additionally, I added the '--host=0.0.0.0' option to allow external access to the app.

2. Made some modifications to the 'src/config.ts' and 'vite.config.ts' files in the 'frontend'.

   • Modified the src/config.ts file
     • Referred to FAQs for the modifications.
   • Modified the vite.config.ts file
     • Added the 'server' configuration to allow external access to the app.

3. Run the 'frontend'

   • Executed 'yarn' and 'yarn dev' commands sequentially on the server.

4. Access the app and run it by uploading an image

   • I was able to confirm that the AI analyzes the image and generates code as shown below.

💡 Please note that I do not have knowledge of Python and React. However, I resolved this issue based on previous responses and my personal research. I appreciate your understanding if there are any shortcomings in the process. 💡 Additionally, please note that the above content is a translation of the original content written in Korean.

Since this issue has been resolved, I will mark it as 'closed'.(if that is appropriate for me to do...😳).

@wdEffort This is awesome, thanks for the detailed write-up. I'll use this to improve the README.
