在virtualenv Python 3.4（Ubuntu 14.04）中安装psycopg2的问题

Question

(my_env)user@web:~/myproject$ pip install psycopg2
Collecting psycopg2
  Using cached psycopg2-2.6.1.tar.gz
setuptools must be installed to install from a source distribution

我安装了setuptools ...我在安装psycopg2之前从未见过这个错误

Answer 1

我有类似的问题并修复了安装python 3 dev：

$sudo apt-get install python3-dev
