Question

我遵循Traversy Media在YouTube视频上的教程。当我输入命令

python manage.py迁移

然后我得到了这样的错误：

C:\Users\Acer\Project\djangoproject>python manage.py migrate

顺便说一句，我已经从另一个错误中安装了C ++ Build Visual Studio，并且还已经安装了 mysqlclient-1.4.4-cp37-cp37m-win32.whl 来完成它。但是，这仍然给了我一个错误。

请帮助我，并感谢您已经对此做出回应的人。

Answer 1

您是否正在使用虚拟环境？如果您不知道我在说什么，请访问this博客，以获取有关什么是虚拟环境的很好的解释。

在此示例中，我将使用virtualenv，但任何虚拟环境都可以。

步骤：

打开CMD /终端，然后cd进入项目文件夹
运行virtualenv ./env && source env/bin/activate (this create the env`目录，并启动您的虚拟环境）
运行pip3 install django mysqlclient （这会将django和mysqlclient安装到您的虚拟环境中）

现在，您的迁移应该可以按预期进行了。

请记住，每次打开新的CMD / Terminal窗口（在根项目文件夹中）时，必须每次运行source env/bin/activate
