django - 如何解决Windows上的Django中需要: ImproperlyConfigured: mysqlclient 1. 3.13或更高版本的错误？

Question

我遵循YouTube视频上Traversy Media的教程。当我发出命令时

python manage.py migrate

然后我得到了这样的错误:

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

ired; you have 0.9.3.

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

您正在使用虚拟环境吗？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良好解释。

对于此示例，我将使用virtualenv，但是任何虚拟环境都可以。

脚步:

在您的项目文件夹

中打开CMD/Terminal和 cd

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，您的迁移将按预期工作。

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