的Django到PostgreSQL：错误加载psycopg2

问题描述：

试图runserver与db['ENGINE'] = 'django.db.backends.psycopg2'我：的Django到PostgreSQL：错误加载psycopg2

与'ENGINE': 'django.db.backends.postgresql_psycopg2'我：

[...]

而且我不应该与Python> 2.6使用psycopg吧？

如何做这项工作的任何帮助？

答

尝试做一个干净的石板。准备分离的virtualenv目录。

sudo apt-get install python-virtualenv # if you don't have it yet 
virtualenv /some/dir/

激活VIRTUALENV

source /some/dir/bin/activate

准备Django和psycopg2和使用

pip install psycopg2 django # possibly other libraries

任何其他库，然后移动到你的项目目录（这与manage.py），确保项目在PYTHONPATH内并再次尝试./manage.py runserver。

自从我写这个答案以来，我的知识增加了，现在我强烈建议熟悉virtualenvwrapper库：https：//virtualenvwrapper.readthedocs.io/en/latest/。当您进行初始设置时，通过它管理virtualenvs会更容易。 – omikron 2016-09-07 08:51:36

您的安装已损坏。也许你运行一个32位的Python，但库是64位。

我用Python2.7运行psycopg2没有问题。
