pip安装：尝试从私有pypi安装同一软件包的多个版本

Question

我有一个私有pypi，并不断将新包framework上传到该注册表

我想在virtualenv中安装最新的软件包

使用的命令：

pip install -i https://user:pass@registry framework

输出：

Collecting framework:
   ... downloads many versions

ERROR: Cannot install framework==0.25.13, framework==0.25.14 and framework==0.26.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    framework 0.26.0 depends on toolz<0.12.0 and >=0.11.1
    framework 0.25.14 depends on toolz<0.12.0 and >=0.11.1
    framework 0.25.13 depends on toolz<0.12.0 and >=0.11.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

我只想下载最新版本。我无法在pip安装时硬编码像framework==0.26.0这样的版本，因为此命令将在脚本中使用，每次上载新的framework时，我可能需要修改脚本

pip版本：pip 21.1.2

解决这个问题的方法是使用 extra-index-url而不是-i

要使用的命令

pip install  extra-index-url https://user:pass@registry framework
