That tutorial requires Django 1.10 while you seem to be using an older version. In this case, you should import reverse as follows:

该教程需要Django 1.10,而您似乎使用的是旧版本。在这种情况下,您应该反向导入,如下所示:

from django.core.urlresolvers import reverse

To upgrade your Django version, use the following command (in your command line, not in the Python shell):

要升级Django版本,请使用以下命令(在命令行中,而不是在Python shell中):

pip install --upgrade django

Latest tutorial (https://docs.djangoproject.com/en/2.0/intro/tutorial01/) uses Django 2.0, which supports Python 3.4 and later

最新教程(https://docs.djangoproject.com/en/2.0/intro/tutorial01/)使用Django 2.0,它支持Python 3.4及更高版本

Since I ran into this same issue I had to upgrade by python as well as django

由于我遇到了同样的问题,我不得不通过python和django进行升级

sudo apt-get -y install python3-pip
pip3 install --upgrade django

to see your django version run following command -

看看你的django版本运行以下命令 -

python3 -c "import django; print(django.get_version())"

for me it says 2.0.1

对我来说它说2.0.1

To check python version run -

检查python版本运行 -

python3 --version

For me it is Python 3.5.2

对我来说这是Python 3.5.2

At times, if one has multiple copies of django running on one's machine like I had, if the current project requires a different version of sjango, it is easier to simply go to preferences -> project interpreter -> add a virtual env -> install latest copy of django. Now pycharm will interpret the project correctly.

有时,如果有一个django的副本像我一样在一台机器上运行,如果当前项目需要不同版本的sjango,则更容易简单地转到首选项 - >项目解释器 - >添加虚拟环境 - >安装django的最新副本。现在pycharm将正确解释项目。
