Raise配置不正確psycopg2（postgresql）

我是django的新手。我試圖用我的項目配置postgresql。步驟是什麼我也跟着：Raise配置不正確psycopg2（postgresql）

1）命令和apt-get安裝psycopg2

2）改變settings.py

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.postgresql_psycopg2', 
     'NAME': 'dbname', 
     'USER': 'postgres', 
     'PASSWORD': 'postgres', 
     'HOST': '', 
     'PORT': '', 
    } 
}

3）執行Python manage.py makemigrations

，但我獲取錯誤

Traceback (most recent call last): 
    File "/home/vivekpradhan/joker/basket/local/lib/python3.4/site-packages/django/db/backends/postgresql_psycopg2/base.py", line 20, in <module> 
    import psycopg2 as Database

您需要安裝'sudo apt-get install python-psycopg2'。 – solarissmoke

其顯示python-psycopg2已經以最新的形式出現 –

您可以嘗試使用下面的命令在你的virtualenv安裝它：

pip install psycopg2

要全局安裝，你可以這樣做：

sudo apt-get install python-dev 
sudo apt-get install libpq-dev 
sudo apt-get install python-psycopg2

當我遇到這個問題雖然包已經安裝，它有助於重新安裝它。不知道爲什麼。

(venv) $ pip uninstall psycopg2 
(venv) $ pip install psycopg2
