网站主页(hexo博客网站主页空白或404)

太久没更新博客了,最近准备拾起来。为了“改头换面”,今天想调整一下 sidebar 上的头像,因为是新电脑,没有 hexo 等环境,于是按照之前分享过的一篇博文,安装 hexo,替换 source 目录下的头像图片并调整 _config.xml,本地预览一切正常,然后直接执行 hexo d部署完成,访问网站域名 www.yangbing.club 发现直接404了,刷新了多次,用无痕浏览,等了许久再试,还是老样子,这可把我吓坏了,从未遇到过这等情况,等于博客直接挂了。web-site-404排查和定位github 上的线索发现 Actions 中此次 hexo deploy 触发的 build 和 deploy 均失败了。build error 如下,/usr/local/bundle/gems/jekyll-3.9.0/lib/jekyll/theme.rb:84:in `rescue in gemspec': The hexo-theme-next theme could not be found.

Sending telemetry for run id 2021541511deploy 不用看,自然是 build 失败导致缺少需要的文件。从 build 错误日志中看到,Error: The hexo-theme-next theme could not be found.这个没改过,我又确认了下 site 目录下的文件夹,hexo-theme-next 是存在的。于是我将其改为 next 试试,还是不行,感觉不是这个问题,此路不通。可能是CNAME失效,导致域名跳转失败?直接访问 https://sherlockyb.github.io 试试,发现并没有出现404,但首页空白,难道 hexo 生成的 index.html 是空的?通过 inspect 看了下首页源码,还真是空白页!除了 html, head 和 body 三对空标签,其他什么内容都没有。github-io-index-empty.png然后也查看了下本地 hexo generate 产生的 public 文件夹,发现不仅 index.html,很多其他文件也都是 zero bytes,local-hexo-generate-empty-file.png于是问题变为 hexo 生成的HTML为空,继续 Google,发现有网友也遇到过类似问题并解决了,原因是,hexo 与 node 的版本不兼容,要么 node 过高,要么 hexo 过低我查了下本地安装的 hexo 版本,./node_modules/hexo/bin/hexo –versionhexo: 3.9.0

hexo-3.9.0 是比较老的版本了,截止发稿最新版本已经是 6.1.0 了,而 node 的版本却高达 15.5.0,是比较符合前面提到的 cause 的,剩下的问题就是如何升级 hexo 或者降级 node 了。解决问题降级 node先看看如何降级 node。先卸载再重装是可以的,且简单粗暴,但并不想这么做,因为已有很多其他项目的前端代码也依赖当前版本的 node,如果因为降级 node 版本而带来未知的影响得不偿失。网上又 Google 了一番,发现有 nvm 这个好东西,可以随时切换指定版本的 node,就它了。安装 nvm先是 brew install nvm ,但执行完后,尝试 nvm 命令时却提示 command not found,按照文中网友说法,通过 brew 安装存在 bug,可用如下脚本安装,curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash在 Mac 下如果遇到如下错误,./install.sh: line 416: /Users/sherlockyb/.zshrc: Permission denied直接进到 nvm 的默认的 git 目录 ~/.nvm,然后执行 sudo ./install.sh,可以看到安装脚本会转而使用 .bash_profile文件,Appending nvm source string to /Users/sherlockyb/.bash_profile安装结束后,重新打开 terminal 查看 nvm 版本如下,表示安装成功。sherlockyb@07L0220100005DD sherlockyb.github.io % nvm –version
0.39.1用 nvm 降级 node 到 12.14.0用法很简单,两行命令就搞定,nvm install 12.14.0
nvm use 12.14.0
这里需注意,nvm use 只是临时切换 node 版本,只适用于当前 terminal,如果打开新的 terminal,node 还是之前的旧版本。如果想要永久切换的话,可使用如下命令,nvm alias default 12.14.0然后再查看 node 版本如下,已经降级了sherlockyb@07L0220100005DD sherlockyb.github.io % node –version
v12.14.0
此时再通过 ./node_modules/hexo/bin/hexo –version 查看 hexo 及其依赖包的版本时如下,node 版本已经变了。hexo: 3.9.0
hexo-cli: 2.0.0
os: Darwin 20.6.0 darwin x64
node: 12.14.0
v8: 7.7.299.13-node.16
uv: 1.33.1

http_parser: 2.8.0
openssl: 1.1.1d
cldr: 35.1
icu: 64.2
tz: 2019c
unicode: 12.1重新生成HTML清除并重新 generate,./node_modules/hexo/bin/hexo clean
./node_modules/hexo/bin/hexo g然后再查看 public 文件夹,会发现 index.html 已经正常生成了,打开后内容也是正常。最后本地预览一下,网站各项功能都没啥问题。local-hexo-generate-successful-file.png部署最后通过 ./node_modules/hexo/bin/hexo d 部署到GitHub Pages,网站恢复正常。升级 hexo降级 node 已经被验证是可行且简单的,不妨再尝试下升级 hexo 会咋样。此次 hexo 是通过 npm install hexo 安装的,得到的默认版本就是 3.9.0,尝试升级 hexo 到最新版。先执行 npm i hexo-cli安装特别慢,这种一般是由于国内访问 npm 默认的外网官方源 https://registry.npmjs.org/ 比较慢,于是将其切换为国内镜像,npm config set registry http://r.cnpmjs.org/再执行上述命令时,发现快很多。此时再查看 hexo 版本,暂时还未变化。再依次执行如下命令npm install npm-check // 安装 npm-check 到当前 node_modules 目录
./node_modules/npm-check/bin/cli.js // 查看系统插件是否需要升级
npm install npm-upgrade
./node_modules/npm-upgrade/lib/bin/cli.js // 更新 package.json
npm update –save // 更新插件
执行完 npm update –save 后,可以看到 hexo 版本升级到了 6.1.0,并且 hexo-deployer-git 等相关 hexo 插件也随之升级了。+ [email protected]

hexo 6.1.0 的 bugGoogle了一番发现,在这个 issue 中找到了答案,貌似是 6.1.0 版本引入了 bug,解决方案是回退到 6.0.0,hexo-bug.png于是通过 npm i [email protected] 回退,执行成功后,再次查看 hexo 版本,回复正常了。hexo: 6.0.0

swig模板失效了然后尝试重新生成 HTML,却发现index.html文件内容长这样,{% extends '_layout.swig' %}
{% import '_macro/post.swig' as post_template %}
{% import '_macro/sidebar.swig' as sidebar_template %}

{% block title %} {{ config.title }} {% endblock %}

{% block page_class %}
{% if is_home() %} page-home {% endif %}
{% endblock %}

{% block content %}
<section id="posts" class="posts-expand">
{% for post in page.posts %}
{{ post_template.render(post, true) }}
{% endfor %}
</section>

{% include '_partials/pagination.swig' %}
{% endblock %}

{% block sidebar %}
{{ sidebar_template.render(false) }}
{% endblock %}
这是 next/layout 下 index.swig 中的原始内容,说明 swig 模板压根没被处理,因为我的 NexT 主题还比较老(5.1.0),用的是 swig,而从该 issue 可得知,鉴于 swig 缺乏维护,hexo 从 5.0 开始移除了对 swig 模板的支持,改为独立的 hexo-renderer-swig 插件,对于 NexT 则是从 7.4.2 版本开始,使用 Nunjucks 代替 swig 作为新的模板引擎。也就是说想要继续使用 swig,需要单独安装 hexo-renderer-swig 插件。顺便看了下 swig 的官网,最新的 Release News 也是两年前了。话不多说,执行 npm install hexo-renderer-swig,然后重新生成 HTML,看了下内容,这回终于正常了。若干小问题通过 ./node_modules/hexo/bin/hexo s 本地预览,网站整体功能是没问题,但又发现若干小问题,sidebar 的头像没有了,据说是 hexo 从 5.4.0 开始就去掉 avatar 的配置项了,交由主题去管理,好在 NexT 5.1.0 是有 avatar 这个配置项的,只不过之前没开启而已,这个还挺容易解决。翻页的button 处,awesome icon 不展示,显示为源码了查看单个博客上下滑动时,左侧目录栏不跟着一起变了从前面降级 node 可以看出,之前 3.9.0 版本的 hexo 还是好的,看起来就是高版本的 hexo 6.0 与低版本的 NexT 5.1.0 有若干不兼容的地方。上面提到的只是通过简单验证发现的问题,可能还有其他未知的问题。当然,这些小问题都是可以通过改配置或者是改源码来修复。放弃并回归 node 降级考虑到时间成本,我就不继续下去了,放弃升级,回滚 hexo 至 3.9.0,最终采用降级 node 的方案。划重点hexo 与 node 版本不兼容,可能导致生成的HTML为空,建议降级 node 更安全。hexo 5.0 之后不再内置支持 swig,若需要,得单独安装 hexo-renderer-swig。nvm 乃管理 node 版本的神器,推荐。
