Troubleshooting Guide for Setting Up HttpRunnerManager with Python, Django, RabbitMQ, MySQL and Related Modules

Before the technical guide, the page shows a short cultural note comparing the northern lantern‑festival snack 元宵 with the southern winter‑solstice snack 汤圆, highlighting differences in ingredients, preparation, and regional customs.

The main content describes the author's experience setting up the HttpRunnerManager environment and lists common pitfalls and solutions.

1. Python version : Use Python 3.0 or higher to ensure compatibility with Django; older 2.x versions may cause issues.

2. RabbitMQ guest login : From RabbitMQ 3.3.0 onward, the default guest account can only log in via localhost; create a new user for remote access.

3. Django version : The default pip install provides Django 1.11.15, which may be incompatible; install a newer version such as pip install django==2.1.1 .

4. djcelery installation : If pip install djcelery fails, install the compatible package with pip install django-celery .

5. mysqlclient installation : Resolve compilation errors by installing Visual C++ or by downloading a matching .whl file from the unofficial Windows binaries site .

6. Database character set : Errors caused by incorrect charset can be fixed by setting the database to UTF‑8 either during creation or by executing SET character_set_database=utf8; after checking with SHOW VARIABLES LIKE '%char%'; .

7. Remote MySQL access : Allow remote connections by updating the MySQL user table: mysql -u root -p USE mysql; UPDATE user SET host='%' WHERE user='root'; FLUSH PRIVILEGES;

8. yaml module : Install the missing PyYAML package with pip install pyyaml to resolve import errors.
