Django在安装django-fcm时得到更新。如何安装django-fcm而不更新django
提问于 2017-01-02 21:30:13
我的django版本是1.8.3。我读到它支持django-fcm。我尝试在我的virtual environment中安装virtual environment
pip install django-fcm不幸的是，运行此命令将我现有的django版本替换为1.10，将djangorestframework从3.2.2替换为3.5.2。
这是原木
pip install django-fcm
Requirement already satisfied: django-fcm in /home/sudheer/virtualenvs/mediaone/lib/python2.7/site-packages
Collecting djangorestframework>=3.3.2 (from django-fcm)

您可以在pip install -h中使用此可用选项。
pip有一个--no-deps选项。
--不安装不安装包依赖项。

或者，将应用程序的依赖项放在需求文件中，这样就可以列出所需的特定版本。当您想更新一个包时，pip将知道您指定的其他包，而不是升级这些包。
