根因分析

两个同名 Blueprint 对象注册到同一个 app，或同一蓝图被注册两次。

English

Two Blueprint objects with the same name are registered on the same app, or a blueprint is registered twice.

解决方案

  1. 95% 成功率 
    Give unique names: `api_v1 = Blueprint('api_v1', __name__)` and `api_v2 = Blueprint('api_v2', __name__)`.
  2. 90% 成功率 
    Register with a prefix: `app.register_blueprint(api, url_prefix='/v1')` and ensure names differ.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Name still collides; url_prefix does not change the blueprint name.

  2. 85% 失败

    Second blueprint's routes are silently dropped.
