首先phantomjs是作为pyspider的一个外部依赖组件部署的。
    apt安装完出现问题报错

    1. QXcbConnection: Could not connect to display
    2. PhantomJS has crashed. Please read the bug reporting guide at
    3. <http://phantomjs.org/bug-reporting.html> and file a bug report.
    4. Aborted
    1. 在/usr/bin/phantomjs的合适位置加上以下设置代码:
    1. export QT_QPA_PLATFORM=offscreen
    2. export QT_QPA_FONTDIR=/usr/share/fonts
    1. phantomjs即可正常运行。<br />参考资料:https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=817277
