hugo-teek is loading...
运行报错

报错背景
自己再it pc上推送 hugo-teek项目后,测试都是没问题的,可以正常运行网站。
来到work pc上,拉取仓库后,本地运行项目后,报错如下:

豆包提问
根据错误信息,核心问题是 $docAnalysis 变量未初始化或为 nil,导致访问 $docAnalysis.fileList 时触发空值错误。以下是分步解决方案:
一、定位出错文件
错误来自主题的 partial 模板:
1themes/hugo-teek/layouts/partials/site-info-card.html
二、修复核心:添加空值判断
打开上述文件,找到第3行(出错行),原代码应该类似:
1{{ len $docAnalysis.fileList }}
由于 $docAnalysis 可能未定义或为 nil,直接访问 fileList 会报错。需要添加双重空值判断:
方案1:简单判断(推荐)
1{{ if and $docAnalysis $docAnalysis.fileList }}{{ len $docAnalysis.fileList }}{{ else }}0{{ end }}
方案2:完整兼容写法(更稳妥)
1{{ $fileCount := 0 }}
2{{ if $docAnalysis }}
3 {{ if $docAnalysis.fileList }}
4 {{ $fileCount = len $docAnalysis.fileList }}
5 {{ end }}
6{{ end }}
7{{ $fileCount }}
三、补充:确保 $docAnalysis 正确定义(可选)
如果 $docAnalysis 是你自己定义的变量,需要在使用前确保它被初始化(避免 nil):
1{{/* 在模板开头添加变量初始化 */}}
2{{ $docAnalysis := .Site.Data.docAnalysis | default (dict "fileList" nil) }}
- 若
docAnalysis是数据文件(data/docAnalysis.yaml),会自动加载 - 若不存在,默认初始化为
{fileList: nil},避免空指针
四、验证修复
修改后重新启动 Hugo 服务器:
1hugo server --source=hugo-teek-site --bind=0.0.0.0 --port=8080 --buildDrafts
如果没有再出现 reflect: call of reflect.Value.Type on zero Value 错误,说明修复成功。
错误原因总结
Hugo 模板中访问嵌套字段时,必须确保每一层都非空:
- 原代码直接访问
$docAnalysis.fileList,但$docAnalysis可能未定义(nil) len函数无法接收nil值,导致反射错误- 通过
and $docAnalysis $docAnalysis.fileList先判断两层非空,再调用len即可避免错误
结论
后面不知道为啥就正常了。。。。🤣🤣🤣
