这篇文章将介绍一个开源项目markdown-pdf的使用，以及遇到的
一个无数个坑
前提
需要node.js环境，没有的请自行百度安装node.js
安装markdown-pdf
这一条是官网的安装教程
解释一下参数，npm是一个node.js的包管理工具，-g是全局安装，指安装后可以作为一个命令使用，--ignore-scripts是忽略一些脚本（package.json中的script）
npm install -g markdown-pdf --ignore-scripts
但是跑着跑着如果发现报错，原因是权限不足，我们在linux和macOS环境下需要sudo
sudo npm install -g markdown-pdf --ignore-scripts
终于成功装好了，赶紧试用一个
jabin@jabin-deepin ~/Code/tmp [16:25:24]
> $ markdown-pdf lesson01.md
internal/validators.js:125
throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
^

又发现了错误！这个错误的解决方法就是先卸载已经装好的模块，去掉--ignore-scripts重装一遍
- 卸载
sudo npm uninstall -g markdown-pdf
- 去掉参数重装
sudo npm install -g markdown-pdf
去掉参数之后，会被检测出来缺少一个模块phantomjs，然后脚本会自动安装，问题是，这个模块的下载速度奇慢无比，挂了10分钟甚至卡在8%不动了

输出信息可以看到链接，尝试使用浏览器下载https://github.com/Medium/phantomjs/releases/download/v2.1.1/phantomjs-2.1.1-linux-x86_64.tar.bz2
发现速度非常慢，原因是中国特有的设施影响了我们的访问 -
可以看到脚本会下载资源，然后放在对应的路径，所以我们手动下载文件然后放在对应的路径，至于文件，你们可以到我的百度云下载，

将文件下载好，放在对应的路径（比如我的输出为
/tmp/phantomjs/文件夹下）
经过测试，macOS和linux的路径都是
/tmp/phantomjs/

发现还是报错，尽管sudo了，还是permission denied，这需要我们在后面加上参数--unsafe-perm，执行sudo npm install -g markdown-pdf --unsafe-perm
