使用 Hexo 遇到的一些问题

·321 words·2 mins· 📖

关于 Hexo 如何使用,网上已经有很多教程了,不再赘述。涉及的几个相关命令也就是:

$ npm install -g hexo
$ hexo init
$ hexo generate (hexo g)
$ hexo server (hexo s)

$ hexo new [name] - 新建文章
$ hexo new page [name] - 新建页面

正常情况下,这样就会启动本地的服务: http://localhost:4000,但现实总是残酷的,

由于国内XXX的网络环境,总会遇到各种各样的问题,

下面总结一下本博客迁移到Hexo过程中遇到的一些问题。

NPM 源 #

node的包管理工具npm,默认使用国外的源,访问比较慢,建议换成国内源,比如 淘宝npm:

$ npm install -g cnpm --registry=https://registry.npm.taobao.org

这样就可以使用cnpm代替npm进行模块安装了:

$ cnpm install [name]

或者,使用nrm (npm的源管理工具):

$ npm install nrm
$ nrm ls
* npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
  taobao - https://registry.npm.taobao.org/
  nj ----- https://registry.nodejitsu.com/
  rednpm - http://registry.mirror.cqupt.edu.cn/
  npmMirror  https://skimdb.npmjs.com/registry/
  edunpm - http://registry.enpmjs.org/
$ nrm use taobao
$ nrm test taobao

Hexo 安装 #

hexo-server #

hexo server执行失败:

ERROR Plugin load filed: hexo-server

需要单独安装hexo-server:

$ npm install hexo-server --save

node-sass #

$ npm install node-sass --save

如果出现如下情况:

$ node scripts/install.js

Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/darwin-x64-51_binding.node": 

read ECONNRESET

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g. 

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

$ node-sass@4.5.3 postinstall /private/tmp/node_modules/node-sass
$ node scripts/build.js

说明 github 访问比较慢,两种方法:

  • 修改 host:

http://tool.chinaz.com/dns?type=1&host=github.com&ip=

找一个TTL比较小的host,如:

192.30.255.112 github.com
  • 直接去github下载

https://github.com/sass/node-sass/releases/download/v4.5.3/darwin-x64-51_binding.node

然后将该文件放到目录:~/.npm/node-sass/4.5.3/darwin-x64-51_binding.node

再执行安装命令

$ npm intall node-sass --save

hexo-renderer-scss #

有些主题需要安装hexo-renderer-scss:

$ npm install hexo-renderer-scss --save

会出现错误:

ERROR Plugin load failed: hexo-renderer-scss
Error: ENOENT: no such file or directory, scandir 'xxx/node_modules/node-sass/vendor'
   at Object.fs.readdirSync (fs.js:914:18)
   ...

提示这个目录找不到,那我们手动创建好了:

$ mkdir xxx/node_modules/node-sass/vendor
$ mkdir xxx/node_modules/hexo-renderer-scss/node_modules/node-sass/vendor

接下来还是报错:

ERROR Plugin load failed: hexo-renderer-scss
Error: Missing binding xxx/node_modules/hexo-renderer-scss/node_modules/node-sass/vendor/darwin-x64-51/binding.node
Node Sass could not find a binding for your current environment: OS X 64-bit with Node.js 7.x

Found bindings for the following environments:

到这个目录下,把刚刚下载的darwin-x64-51_binding.node重命名复制进去好了:

$ mkdir xxx/node_modules/hexo-renderer-scss/node_modules/node-sass/vendor/darwin-x64-51/
$ cp darwin-x64-51_binding.node xxx/node_modules/hexo-renderer-scss/node_modules/node-sass/vendor/darwin-x64-51/binding.node

页面空白 #

有时执行hexo s后显示服务启动,但页面打开空白,显示Cannot GET /,这种情况有很多原因,

可以尝试:

$ npm install
$ hexo cl
$ hexo g
$ hexo s

如果还有问题,查看一下npm插件是否安装正常:

$ npm ls --depth 0
hexo-site@0.0.0 xxx
├── hexo@3.3.9
├── hexo-deployer-git@0.3.1
├── hexo-generator-archive@0.1.4
├── hexo-generator-baidu-sitemap@0.1.2
├── hexo-generator-category@0.1.3
├── hexo-generator-feed@1.2.2

└── node-sass@4.5.3

npm ERR! invalid: hexo-generator-baidu-sitemap@0.0.8 xxx/node_modules/hexo-generator-baidu-sitemap/node_modules/hexo-generator-baidu-sitemap

可以看到hexo-generator-baidu-sitemap这个插件安装失败了,尝试重新安装或者删除它:

$ npm install hexo-generator-baidu-sitemap --save
$ npm uninstall hexo-generator-baidu-sitemap

或者在package.json中将它删除掉。
