django错误无法导入名称'RemovedInDjango30Warning'

标签： django python-3.x pycharm

伙计们对Django来说还很陌生，我刚开始从事个人项目，并决定使用不当的pycharm（我认为它与错误有关，或与错误无关）。

运行python manage.py runserver时出现以下错误。我做了一些谷歌搜索，看起来它是由与Django版本不一致引起的。

我目前拥有Django 3.0，并且在全局和虚拟环境中都进行了检查。

我试图在py charm之外启动一个项目，而我遇到了同样的问题。 idk我需要做些什么才能再次开始使用Django。有人碰到这个吗？是因为pycharm吗？如果可以，该怎么办才能解决此问题？

答案 0 :(得分：7)

这是由Django版本中的冲突引起的

尝试卸载Django 

sudo pip uninstall django

并使用低于3.0的版本重新安装

sudo pip install django==2.2

答案 1 :(得分：1)

从django.utils.deprecation导入RemovedInDjango30Warning

在以下文件中注释此行

python3.6 / site-packages / django / contrib / admin / templatetags / admin_static.py .python3.6 / sitepackages / django / contrib / staticfiles / templatetags / staticfiles.py

答案 2 :(得分：1)

这是由Django版本引起的。您可能已对其进行升级。

如果您不想返回到版本2，请创建一个虚拟环境并执行pip install django == 2.2

答案 3 :(得分：0)

此错误取决于python，pip和django版本。此错误主要是在python2上运行最新的django版本引起的。

安装python3版本

使用

之类的命令

pip3安装Django

python3 manage.py运行服务器

答案 4 :(得分：0)

我遇到了同样的问题。 由于2版本的python或django会出现此问题。 因此，如果您通过虚拟环境（venv）运行项目，请检查其中的python版本。 通过直接输入以下内容：

myproject/venv/lib/pythonx.y

请确保x.y是您在项目中使用的python版本。 或者，如果您不是通过venv运行项目的，请检查项目正在使用并在其上运行的python版本。

python --version

答案 5 :(得分：0)

TL;DR 这似乎来自站点包中损坏的 Django 安装。删除 Django 并重新安装。

对我来说，我正在将现有项目从 Django 2.2.6 升级到 3.1.7。看来 2.2.6 中的文件不知何故仍在徘徊。我必须运行 pip unintall django 两次才能恢复原状，然后 pip install django 才能安装最新版本。
