1. 解决fs.SyncWriteStream报错问题
在执行hexo命令的时候，总会显示如下报错：
1 (node:7048 ) [DEP0061 ] DeprecationWarning: fs.SyncWriteStream is deprecated.
从报错信息来看是因为fs.SyncWriteStream is deprecated，node.js从8.0开始已经弃用了fs.SyncWriteStream方法，所以是因为我们node_modules中某个插件调用了这个方法，通过查看Hexo作者GitHub对应的项目，在issue中看到有人提到这个问题 ，在hexo项目中其中有一个hexo-fs的插件调用了这个方法，所以需要更新hexo-fs插件，更新方法如下：
1 npm install hexo-fs --save
更新插件后问题解决。
但是不知道怎么回事，后面又出现了这个报错，而且更新插件也不管用了，强迫症忍不了啊，网上查了很久都找不到解决方法，终于自食其力，hexo命令有个–debug参数，我们在运行hexo命令的时候添加上这个参数，就能知道在哪里报的错误，如此就能定位问题所在，例如：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 $ hexo clean --debug 02 :35 :27.359 DEBUG Hexo version: 3.3 .8 02 :35 :27.362 DEBUG Working directory: E:\github\blog\ 02 :35 :27.502 DEBUG Config loaded: E:\github\blog\_config.yml 02 :35 :27.531 DEBUG Plugin loaded: hexo-generator-archive 02 :35 :27.534 DEBUG Plugin loaded: hexo-generator-category 02 :35 :27.542 DEBUG Plugin loaded: hexo-generator-feed 02 :35 :27.550 DEBUG Plugin loaded: hexo-generator-baidu-sitemap 02 :35 :27.554 DEBUG Plugin loaded: hexo-generator-index 02 :35 :27.582 DEBUG Plugin loaded: hexo-deployer-git (node:5760 ) [DEP0061 ] DeprecationWarning: fs.SyncWriteStream is deprecated. 02 :35 :27.593 DEBUG Plugin loaded: hexo-generator-searchdb 02 :35 :27.597 DEBUG Plugin loaded: hexo-generator-sitemap 02 :35 :27.603 DEBUG Plugin loaded: hexo-fs 02 :35 :27.608 DEBUG Plugin loaded: hexo-renderer-ejs 02 :35 :27.616 DEBUG Plugin loaded: hexo-renderer-marked 02 :35 :27.697 DEBUG Plugin loaded: hexo-renderer-less 02 :35 :27.700 DEBUG Plugin loaded: hexo-renderer-stylus 02 :35 :27.775 DEBUG Plugin loaded: hexo-wordcount 02 :35 :27.878 DEBUG Plugin loaded: hexo-server 02 :35 :27.883 DEBUG Script loaded: themes\next\scripts\merge-configs .js 02 :35 :27.887 DEBUG Script loaded: themes\next\scripts\merge.js 02 :35 :27.890 DEBUG Plugin loaded: hexo-generator-tag 02 :35 :27.891 DEBUG Script loaded: themes\next\scripts\tags\center-quote .js 02 :35 :27.892 DEBUG Script loaded: themes\next\scripts\tags\button.js 02 :35 :27.893 DEBUG Script loaded: themes\next\scripts\tags\full-image .js 02 :35 :27.895 DEBUG Script loaded: themes\next\scripts\tags\group-pictures .js 02 :35 :28.260 DEBUG Plugin loaded: hexo-renderer-jade 02 :35 :28.264 DEBUG Script loaded: themes\next\scripts\tags\exturl.js 02 :35 :28.265 DEBUG Script loaded: themes\next\scripts\tags\lazy-image .js 02 :35 :28.266 DEBUG Script loaded: themes\next\scripts\tags\note.js 02 :35 :28.268 INFO Deleted database. 02 :35 :28.271 DEBUG Database saved
可以看到我所在报错的位置是hexo-deployer-git，于是在hexo-deployer-git中搜索：
1 2 $ grep -irn "SyncWriteStream" .\node_modules\hexo-deployer-git \.\hexo-deployer-git \/node_modules/hexo-fs /lib/fs.js:718 :exports.SyncWriteStream = fs.SyncWriteStream;
可以看到是在.\hexo-deployer-git/node_modules/hexo-fs/lib/fs.js的第718行用到的，进去后把这一行注释掉问题就解决了，但是为什么会在hexo-deployer-git中有个node_modules，而且在其中还有个hexo-fs呢，因为在根目录node_modules中也有个hexo-fs目录，进去hexo-deployer-git官方Github网址 查看是没有node_modules目录的，但是通过npm命令npm install hexo-deployer-git –save安装的hexo-deployer-git是有的，所以应该是npm源没有更新？
总之是解决了这个强迫症难以忍受的问题，通过–debug参数定位问题。
7月28日更新：
在hexo Github issue 中反馈后，已经可以通过npm更新最新版本的hexo-deployer-git以及其他包含旧版本Hexo-fs的插件了，通过npm install –save xxx就可以解决了。
FYI, the following packages may contain the old version of Hexo-fs have been updated.
hexo-deployer-git 0.3.1
当然还有hexo-fs，更新如上几个插件即可解决。

参照上图，阿里云控制台 - 域名 - 解析，值改为 185.199.111.153（ Github Page 公布的 IP ，开始改为 185.199.110.153 过了一会儿还是显示错误，就通过电脑 ping xxx.github.io 得到的了这个 IP），修改解析 IP 即可。
