$ mkdir /tmp/gitbook $ gitbook build --output=/tmp/gitbook
2.2 输出PDF
输入为PDF文件，需要先使用NPM安装上gitbook pdf：
$ sudo npm install gitbook-pdf -g
我在执行上面这条命令的时候出现了下面的错误：

由错误报告内容的第一行可以知道，发生错误的原因是下载
phantomjs发生了错误，因此我们需要手动下载和安装。
解决方法：[1]
$ git clone git://github.com/ariya/phantomjs.git $ sudo apt-get install build-essential g++ flex bison gperf ruby perl libsqlite3-dev libfontconfig1-dev libicu-dev libfreetype6 libssl-dev libpng-dev libjpeg-dev python libx11-dev libxext-dev #安装编译需要的工具和依赖 $ cd phantomjs $ git checkout 1.9.7 #注意：这里的1.9.7是phantom的版本号，可以由错误报告的第一行找出 $ ./build.sh --jobs 4 $ sudo cp bin/phantomjs /bin/ $ sudo npm install gitbook-pdf -g #重新进行安装
然后，使用下面的命令，要PDF文件，首先安装依赖库：
$ sudo apt-get install calibre $ gitbook -v 2.1.0 pdf .
发生错误：

Usage: ebook-convert input_file output_file [options]
Convert an ebook from one format to another.
input_file is the input and output_file is the output. Both must be specified as the first two arguments to the command.
The output ebook format is guessed from the file extension of output_file. output_file can also be of the special format .EXT where EXT is the output file extension. In this case, the name of the output file is derived the name of the input file. Note that the filenames must not start with a hyphen. Finally, if output_file has no extension, then it is treated as a directory and an "open ebook" (OEB) consisting of HTML files is written to that directory. These files are the files that would normally have been passed to the output plugin.
After specifying the input and output file you can customize the conversion by specifying various options. The available options depend on the input and output file types. To get help on them specify the input and output file and then use the -h option.
For full documentation of the conversion system see
http://manual.calibre-ebook.com/conversion.html
Whenever you pass arguments to ebook-convert that have spaces in them, enclose the arguments in quotation marks.
ebook-convert: error: no such option: --pdf-default-font-size
