问题描述

试图为 django 项目准备一个服务器，但我在设置 postgres 时遇到了一些问题.

我正在遵循本指南:https://jee-appy.blogspot.com/2017/01/deply-django-with-nginx.html

我在第 5 步:

<块引用>

  1. 现在，我们需要配置 postgreSQL，以便它可以与我们的 Django 应用程序进行通信.为此，安装 psycopg2 数据库适配器.但是这个适配器有一些包依赖，所以首先安装它们.

运行:

(django_env) $ sudo apt-get install libpq-dev python3-dev

然后...

(django_env) $ pip install psycopg2

我这样做了，在说明中的这一点，我收到了编译失败"错误.

我尝试了这个堆栈交换问题中建议的解决方案:与 Django 一起使用的 virtualenv python3 中的 psycopg2 问题还有这个:无法在 virtualenv 上安装 psycopg2

我非常喜欢 linux 和 django noob，所以如果这是一个重复的问题，请原谅我并发表评论，解释为什么你在这样做时将其标记为重复.

感谢您的时间！

这是导致它的输出和安装命令:

解决方案

您已经为 Python 3 安装了 python-dev 库.您的 psycopg2 安装使用的是 python 2.7

确保你已经安装了 python3-pip

sudo apt-get install python3-pip

那么:

pip3 安装 psycopg2

如果仍然失败，请尝试为 postgresql 安装开发头文件:

sudo apt install python3-dev libpq-devpip3 安装 psycopg2

如果在 Python 2 上

sudo apt updatesudo apt-get 安装 postgresql postgresql-contrib须藤 apt-get 安装 libpq-dev须藤 apt-get 安装 python-dev须藤 apt-get 安装 python-pippip2 安装 psycopg2-binary

如果在 Ubuntu 20.04 上

sudo apt-get install build-essential

然后为 Python 2 或 3 运行其他步骤.

Trying to get a server ready for a django project and I'm running into some issues with setup for postgres.

I'm following this guide: https://jee-appy.blogspot.com/2017/01/deply-django-with-nginx.html

And I'm at step 5:

  1. Now, we need to configure postgreSQL so that it can communicate with our Django application. For this, install psycopg2 database adapter. But this adapter have some package dependencies, so first install them.

run:

(django_env) $ sudo apt-get install libpq-dev python3-dev

then...

(django_env) $ pip install psycopg2

I do that, and this point in the instructions, I get a "compilation failed" error.

I tried the solutions suggested in this stack exchange question: Trouble with psycopg2 in virtualenv python3 for use with Django and this one: Cannot install psycopg2 on virtualenv

I am very much a linux and django noob, so if this is a duplicate issue, please have mercy on me and leave a comment explaining why you are marking it as a duplicate as you do so.

Thanks for your time!

解决方案

You've installed the python-dev libraries for Python 3. Your psycopg2 install is using python 2.7

Make sure you've installed python3-pip

sudo apt-get install python3-pip

Then:

pip3 install psycopg2

If that still fails, try installing the development headers for postgresql:

sudo apt install python3-dev libpq-dev
pip3 install psycopg2

If on Python 2

sudo apt update
sudo apt-get install postgresql postgresql-contrib
sudo apt-get install libpq-dev
sudo apt-get install python-dev
sudo apt-get install python-pip
pip2 install psycopg2-binary

If on Ubuntu 20.04

sudo apt-get install build-essential

Then run the other steps for either Python 2 or 3.
