[英]How to install Psycopg2 for python3 on Ubuntu16.04
I have run sudo apt-get install python3-dev
and the up-to-date pip. 我已经运行
sudo apt-get install python3-dev
和最新的pip。
But when I ran pip install psycopg2
, I got this error: 但是当我运行
pip install psycopg2
,出现了此错误:
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'
Then after searching, some solution indicates I should change the ownership of the directory. 然后在搜索之后,一些解决方案表明我应该更改目录的所有权。 So I tried
chown -R flint1025:27 /usr/local/lib/python2.7/dist-packages/psycopg2-2.7.1.dist-info
but got this error: 所以我尝试了
chown -R flint1025:27 /usr/local/lib/python2.7/dist-packages/psycopg2-2.7.1.dist-info
但遇到了这个错误:
chown: cannot access '/usr/local/lib/python2.7/dist-packages/psycopg2-2.7.1.dist-info': No such file or directory
What should I do next? 接下来我该怎么办?
Seems like you are not installing in virtualenv
,so you have to use : sudo pip install psycopg2
好像您没有在
virtualenv
安装,所以您必须使用: sudo pip install psycopg2
Installing package without using virtual environment you need
root
permissions.在不使用虚拟环境的情况下安装软件包,您需要
root
权限。
