Summary of Changes

Hello @Hahihula, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the simple setup experience by introducing an automated Python installation mechanism specifically for Windows users. Previously, a failed Python sanity check would immediately halt the setup with an error. Now, the system will first attempt to resolve the missing Python dependency automatically, significantly improving the user's initial setup journey. Error messages are still provided as a fallback if the automated installation is unsuccessful or if the issue occurs on a non-Windows platform.

Highlights

• Automatic Python Installation on Windows: The simple setup process now includes logic to automatically attempt Python installation if a sanity check fails on Windows operating systems.
• Enhanced Error Handling: If the automatic Python installation on Windows fails, or if the operating system is not Windows, the system will revert to displaying a user-friendly error message regarding Python prerequisites.

Code Review

This pull request adds automatic Python installation on Windows if the sanity check fails during simple setup. However, the current implementation has a logical flaw: if the automatic installation fails, the setup process continues without showing an error to the user. I've suggested a refactoring to fix this bug and improve code clarity by separating the installation attempt from the final sanity check and error handling.

[gemini-code-assist]

The current logic for handling Python installation on Windows is flawed. If the automatic installation fails, python_sane remains false, but the setup process continues without displaying an error. This can lead to subsequent failures without a clear reason for the user.

I suggest refactoring this block to first attempt the installation on Windows if needed, and then perform a single, final check for python_sane. This approach avoids code duplication for error handling and makes the logic clearer.

          let python_sane = await invoke("python_sanity_check", {});
          if (!python_sane && appStore.os === 'windows') {
            console.log("Python sanity check failed - attempting automatic installation");
            try {
              await invoke("python_install", {});
              python_sane = await invoke("python_sanity_check", {});
            } catch (error) {
              console.error('Automatic Python installation failed:', error);
              python_sane = false;
            }
          }

          if (!python_sane) {
            console.log("Python sanity check failed");
            errorTitle.value = t('simpleSetup.error.prerequisites.python.title');
            errorMessage.value = t('simpleSetup.error.prerequisites.python.message');
            errorDetails.value = t('simpleSetup.error.prerequisites.python.details');
            currentState.value = 'error';
            return false;
          } else {
            console.log("Python sanity check passed");
          }
