Django 在安装 django-fcm 时得到更新。如何在不更新django的情况下安装django-fcm

Question

我的django版本是1.8.3。我读到它支持 django-fcm。我尝试使用

在我的 virtual environment 中安装 django-fcm

pip install django-fcm

遗憾的是运行此命令将我现有的 django 版本替换为 1.10 并将 djangorestframework 从 3.2.2 替换为 3.5.2

这是日志

pip install django-fcm

有什么办法可以防止这种情况发生。我只想安装 django-fcm

Answer 1

您可以通过 pip install -h

使用此可用选项

pip 有一个 --no-deps 选项。

--no-deps 不安装依赖包

Answer 2

或者，将应用程序的依赖项放在需求文件中，您可以在其中列出所需的特定版本。当你想更新一个包时，pip 会知道你指定的其他包，而不是升级包。

requirements.txt

django==1.8.3
djangorestframework==3.2.2
django-fcm==<some version>

然后安装

pip install -r requirements.txt
