Linxu下安装Hexo

发表于 更新于 分类于 本文字数： 1.6k 阅读时长 ≈ 6 分钟

为了搭建博客，需要安装hexo，但是在Ubuntu 14.04下怎么都装不上，最后改用了淘宝的源

首先确保你安装了node.js

开始安装：

1
npm install hexo -g

NOTE: 不过这样一直装不上，最后没办法改用了taobao的npm源
使用教程也很简单，有介绍：

1
2
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install [name]

所以如果安不上，试试上面的命令，然后接着安装：

1
2
3
npm install hexo -g  #-g表示全局安装, npm默认为当前项目安装
cnpm install hexo-cli -g
cnpm install hexo --save

创建Hexo文件夹

#安装 Hexo 完成后，请执行下列命令，Hexo 将会在指定文件夹中新建所需要的文件。
hexo init <folder>
cd <folder>
cnpm install

最后的目录结构如下：

启动服务看效果

1
hexo server

然后访问http://localhost:4000/就可以打开网站了。

将Hexo发布到github上

这里踩了很多坑，特别注意一下，因为大多数教程都是以2.x.x版本为例的，问题就在这里，3.x.
x的版本很不一样。所以很多教程根本不对，先看看我的环境：

uv: 1.7.4
zlib: 1.2.8
ares: 1.10.1-DEV
modules: 46
openssl: 1.0.2d

现在我们来重新看看如何发布一个项目到之前你的github博客仓库里，并且直接在github上显示

  • 初始化一个项目

➜  note  hexo generate

ERROR Try running: 'npm install hexo --save'

忘了执行install命令了。

# Deployment
## Docs: http://hexo.io/docs/deployment.html
deploy:
  type: git
  repository: http://github.com/sjq597/sjq597.github.io.git
  branch: master

NOTE: type填git，不要填github，网上的教程都是填github，但是这是hexo 2.x.x的方法，对于3.x.x的版本，必须填git。repository也不要填ssh地址，要填https地址，并且把https改为http，分支都是master。

发布到github

发布到github之前还必须要安装一个东西：

└── hexo-fs@0.1.4 (escape-string-regexp@1.0.3, graceful-fs@4.1.2, bluebird@2.10.1, chokidar@1.1.0)

然后就可已发布了。

常见问题

  • YAMLException

FATAL Something\'s wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html
YAMLException: can not read a block mapping entry; a multiline key may not be an implicit key at line 13, column 1:
    # URL
    ^

NOTE: YML语法校验比较严格，冒号后面必须要有个空格，切记。配置文件里所有的修改地方都要记得在冒号后空格一下。

  • Deployer not found: github
1
2
➜  note  hexo d           
ERROR Deployer not found: github

NOTE: 参见前面说的，3.x.x版本需要把type设置为git而不是github,并且仓库地址要写git的https地址，并且要改为http开头。

然后再去访问你在github上的博客地址，就会发现变成了hexo的index.html。

  • Error: watch ENOSPC

在终端输入:

1
➜  npm dedupe

如果还不管用,试试下面的命令:

1
➜  echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
