Question

我已经运行了sudo apt-get install python3-dev和最新的点子。

但是当我跑pip install psycopg2时，我收到了这个错误：

Collecting psycopg2
  Using cached psycopg2-2.7.1-cp27-cp27mu-manylinux1_x86_64.whl
Installing collected packages: psycopg2
Exception:
Traceback (most recent call last):

    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/psycopg2-2.7.1.dist-info'

然后搜索后，一些解决方案表明我应该更改目录的所有权。所以我尝试chown -R flint1025:27 /usr/local/lib/python2.7/dist-packages/psycopg2-2.7.1.dist-info但是遇到了这个错误：

chown: cannot access '/usr/local/lib/python2.7/dist-packages/psycopg2-2.7.1.dist-info': No such file or directory

接下来我该怎么做？

好像你没有安装在virtualenv中，所以你必须使用：sudo pip install psycopg2

在不使用虚拟环境的情况下安装软件包root 权限。
