问题描述
我正在使用Django 2.0版开发的数字海洋飞沫服务器上部署django应用程序。
使用Putty SSH进入我的ubuntu服务器,我尝试使用 pip install Django == 2.2
进行升级。我收到以下错误消息:
I am deploying a django app on a digital ocean droplet server that I developed using Django version 2.0.Using Putty to SSH into my ubuntu server, I try to upgrade using pip install Django==2.2
. I get the following error message:

1.11.18, 1.11.20)
No matching distribution found for Django==2.2
其中显然是不正确的。我在这里缺少什么升级?
我曾在一段时间前看到类似的帖子,当时有人收到相同的错误消息,但这是因为他们正在搜索尚未发布的版本。
Which is obviously not true. What am I missing here to upgrade?I saw a similar post from awhile ago when someone was getting the same error message, but that was because they were searching for a version that was not released yet. The version I am trying to get is clearly available.
在尝试升级Django之前,我已经做到了:
Before I tried to upgrade Django I did:
$ sudo apt update
$ sudo apt install python3-django
推荐答案
pip
通常是Python-2.x的软件包管理器。 Django-1.11是可与Python-2.x一起使用的Django的最新版本:Django-2.0,仅适用于Python-3.4或更高版本,如的文档。
pip
is usually the package manager for Python-2.x. Django-1.11 is the last version of Django that works with Python-2.x: Django-2.0, only works on Python-3.4 or higher, as is specified in the documentation on installing Django [Django-doc].
因此,包管理器不能找不到找到Django-2.2,因此出现错误。您可能仍然想使用Python-3.x。因此,您可以使用Python-3.x的软件包管理器安装软件包: pip3
:
Therefore the package manager can not find Django-2.2, hence the error. You likely want to use Python-3.x anyway. So you can install the package with the package manager for Python-3.x: pip3
:
pip3 install Django==2.2
