【未解决】gitbook安装和使用插件autocover给生成的pdf文件加上封面
期间，去

期间gitbook报错：

试试：

结果：
问题依旧。

解决了问题。
【总结】
此处是gitbook下面的npm中的插件graceful-fs报错的：
/usr/local/lib/node_modules/gitbook-cli/node_modules/npm/node_modules/graceful-fs/polyfills.js:287 if (cb) cb.apply(this, arguments) ^ TypeError: cb.apply is not a function
而这个错误是：graceful-fs
之前的老版本的错误。最新版已修复。
解决办法：
去给gitbook-cli中安装最新版的graceful-fs
步骤：
cd /usr/local/lib/node_modules/gitbook-cli/node_modules/npm/node_modules/ npm install graceful-fs@latest --save
即可。
