Django报错：使用staticfiles应用却未配置必需的STATIC_URL

问题原因 #

你的settings.py文件中静态文件URL配置项拼写错误：将STATIC_URL误写为STATIC_URl（字母L为小写），导致Django的staticfiles应用无法识别该配置，触发报错。

问题代码（settings.py错误片段） #

# 错误拼写：STATIC_URl（小写L）
STATIC_URl = "/static/"

修正方案 #

将配置项拼写修正为正确的STATIC_URL（大写L）：

# 正确拼写：STATIC_URL
STATIC_URL = "/static/"

修正后重启Django服务，报错即可解决。
