我在manjaro。我刚刚从mysql迁移到postgresql。在安装 postgresql 遇到很多困难后,我收到错误:( 想要安装 psycopg2 时的最终结果:
pip install psycopg2
结果是:

我要做什么来安装它?!
djang versin:3 os:manjaro postgresql from aur (last version)
我可以在没有 psycopg2 的情况下使用 postgres 吗????
解决方案
答案就在您向我们展示的错误中:
您可以通过从 PyPI 安装“psycopg2-binary”来安装二进制包。如果您想从源代码安装 psycopg2,请安装构建所需的软件包并重试。
因此,在从源代码安装之前尝试pip install psycopg2-binary
或确保已安装。gcc
请注意,即使在您安装之后gcc
,也可能会出现其他错误,在这种情况下,您还需要安装这些缺少的软件包,直到不再有错误为止。在常见的 Linux 发行版上,您会发现build-essential
包含用于构建其他包的最常见包的包。在 Manjaro/Arch linux 上,这是base-devel
包。
