今天在安装ATCG的GDC Data Transfer Tool 软件过程中，安装几个依赖的python包时出现以上错误。大致估计可能是python版本的问题。我pip安装的是3.x的版本，这个包可能用的是2.x的版本。

用2.x的版本安装后报错问题解决

安装完成后运行./gdc-client命令时，再次报错

ImportError: /public/home/zzh/.pyenv/versions/2.7.13/lib/python2.7/site-packages/lxml-3.5.0b1-py2.7-linux-x86_64.egg/lxml/etree.so: undefined symbol: xmtent

谷歌了一下，可能是lxml依赖的一些 libraries 未安装。
