还需要安装phantomjs的所需库，phantomjs官网说明如下

Note: For this static build, the binary is self-contained.
There is no requirement to install Qt, WebKit, or any other libraries.
It however still relies on Fontconfig (the package fontconfig or libfontconfig, depending on the distribution).
The system must have GLIBCXX_3.4.9 and GLIBC_2.7.

windows版chrome建议检查一下数字签名是否正常后再安装
mac和linux我不知道咋检查数字签名
