解决方案

  1. 95% 成功率 
    Ensure the template is at 'templates/index.html' relative to the Flask app root.
  2. 70% 成功率 
    Use render_template_string with inline HTML as a temporary workaround.

无效尝试

常见但无效的做法:

  1. 60% 失败

    Changing the template folder to an absolute path may break when the app is deployed.

  2. 80% 失败

    Creating the template in the wrong directory (e.g., static) does not help.
