安装核心拱

Question

我正在尝试安装core Archshttps://arches.readthedocs.io/en/stable/installation/#install-arches-with-pip，在尝试执行pip安装Archs时出现以下错误。我是python新手，我所需要的就是安装Archs

ERROR: Cannot install arches==5.0, arches==5.1.0, arches==5.1.1, arches==5.1.2, arches==5.1.3 and arches==5.1.4 because these package versions have conflicting dependencies.

The conflict is caused by:
    arches 5.1.4 depends on psycopg2-binary==2.8.4
    arches 5.1.3 depends on psycopg2-binary==2.8.4
    arches 5.1.2 depends on psycopg2-binary==2.8.4
    arches 5.1.1 depends on psycopg2-binary==2.8.4
    arches 5.1.0 depends on psycopg2-binary==2.8.4
    arches 5.0 depends on psycopg2-binary==2.8.4

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

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies
WARNING: You are using pip version 21.1.3; however, version 21.2.2 is available.
You should consider upgrading via the 'c:\users\user\appdata\local\programs\python\python39\python.exe -m pip install --upgrade pip' command.

Answer 1

先跑 pip install psycopg2-binary 然后跑 pip install arches 在你的终端
