我的项目正在运行 postgreSQL，在我将系统升级到 ubuntu 16.04 并再次克隆该项目后，我无法安装特定的包。

(temp) hellrazor@hellrazor-desktop:~/workspace/te___ave/backend/te___ave$ pip install psycopg2==2.6 > ERROR.txt
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-f6rRmm/psycopg2/
(temp) hellrazor@hellrazor-desktop:~/workspace/te___ave/backend/te___ave$
