下载gitbook
npm install gitbook-cli -g初始化项目
gitbook init初始化时报错，
E:\node_globalnode_modulesgitbook-clinode_modulesnpmnode_modulesgraceful-fspolyfills.js:287
if (cb) cb.apply(this, arguments)
^
TypeError: cb.apply is not a function
at E:\node_globalnode_modulesgitbook-clinode_modulesnpmnode_modulesgraceful-fspolyfills.js:287:18
at FSReqCallback.oncomplete (node:fs:199:5)解决方案为：
cd node_global/node_modules/gitbook-cli/node_modules/npm/node_modules/
npm install graceful-fs@latest --save即将graceful-fs更新到最新。请参考Stack Overflow.
修改后gitbook init 无任何报错，但未生成README.md和SUMMARY.md，手动生成也无法构建。
解决方案为：
npm install gitbook-cli@2.1.2 --global此时在执行gitbook init，发现只生成了README.md，手动创建SUMMARY.md。
构建
gitbook serve
gitbook build结合github 部署gitbook
创建另一个page分支，用于发布构建的gitbook。
PS F:\codedb021> git branch
* master
page然后构建gitbook，
growd@DESKTOP-0ED5P84 MINGW64 /f/code/db021 (master)
$ gitbook build

growd@DESKTOP-0ED5P84 MINGW64 /f/code/db021 (master)
$ ls
_book/ img/ part2.md part4.md part6.md part8.md SUMMARY.md
code/ part1.md part3.md part5.md part7.md README.md构建成功后可以看到目录下多了一个_book目录，将这个目录重命名为docs然后提交到github上（github只能识别/docs或者/），然后开启page功能，选定分支为page。
growd@DESKTOP-0ED5P84 MINGW64 /f/code/db021 (master)
$ mv _book/ docs
$ git checkout page
Switched to branch 'page'
$ git add docs
$ git commit -m "update docs"
$ git push origin master
