【问题描述】：

我正在处理一个 Django 项目，当我想在本地运行它时，我得到以下信息：

ImportError: cannot import name 'render_to_response' from 'django.shortcuts'

但是，正如我检查的那样，我没有在项目的任何地方包含 render_to_response 方法。我相信这可能是任何库之间的不兼容问题，虽然我不能说。

我的python版本是3.7，我的Django版本是3.1，我的pip版本是20.2.2。

我的 pip freeze 返回：

allauth-django==0.42.6
asgiref==3.2.10
certifi==2020.6.20
chardet==3.0.4
defusedxml==0.6.0
Django==3.1
django-crispy-forms==1.9.2
django-filter==2.3.0
django-tables2==2.3.1
idna==2.10
mysqlclient==2.0.1
oauthlib==3.1.0
python3-openid==3.2.0
pytz==2020.1
requests==2.24.0
requests-oauthlib==1.3.0
sqlparse==0.3.1
tablib==2.0.0
urllib3==1.25.10

任何帮助将不胜感激。

完整的堆栈跟踪是这样的：

更新

当我尝试卸载它并安装 allauth-django 0.42.0 时，使用命令 pip install allauth-django==0.42.0，我收到以下错误：

ERROR: Could not find a version that satisfies the requirement django-utils==0.4.7 (from allauth-django==0.42.0) (from versions: 0.0.1, 0.0.2)
ERROR: No matching distribution found for django-utils==0.4.7 (from allauth-django==0.42.0)

如果我只使用pip install allauth-django，它会自动选择版本0.42.6。

【问题讨论】：

回溯显示导入在C:\Users\IvanH\PycharmProjects\sare_project\venv\lib\site-packages\allauth\django_utils\admin.py。最新的allauth 版本是0.42.0 - 我很惊讶你的pip freeze 显示0.42.6。我会尝试卸载allauth，然后重新安装。

当我这样做时，卸载它并使用 [pip install allauth-django==0.42.0] 重新安装，我得到这个：错误：找不到满足要求的版本 django-utils= =0.4.7（来自 allauth-django==0.42.0）（来自版本：0.0.1、0.0.2）错误：找不到 django-utils==0.4.7 的匹配分布（来自 allauth-django==0.42 .0)

但是当我只使用 [pip install allauth-django] 时它会自动选择 0.42.6 并且没有显示错误。

您应该查看这个答案，这可能会有所帮助：***.com/questions/55911435/…

我看到了，但在那种情况下，他正在使用该方法，并且是使用另一个方法的问题，因为我知道 render_to_response 已被弃用，但在我的情况下，我认为这是一个包问题，而且我不知道 wny 在其内部代码中是 allauth，显然，导入了该方法，该方法已在 Django 3.0+ 中删除

【参考方案1】：

这可以通过三个步骤简单地解决，在你的终端上按照给定的顺序运行这些命令：

pip 卸载 allauth-django pip 卸载 django-allauth pip install django-allauth 你可以走了。
