无法在 macOS Monterey 12.3 上安装 psycopg2-binary

Question

我一直在尝试为我的 django 项目安装 psycopg2-binary，但到目前为止没有任何效果。它一直要求 pg_config 文件，据我所知，只有在构建 psycopg2 时才需要该文件。那么，这里发生了什么？

Collecting psycopg2-binary

      pg_config is required to build psycopg2 from source.  Please add the directory
      containing pg_config to the $PATH or specify the full executable path with the
      option:
      
          python setup.py build_ext --pg-config /path/to/pg_config build ...
      
      or with the pg_config option in 'setup.cfg'.
      
      If you prefer to avoid building psycopg2 from source, please install the PyPI
      'psycopg2-binary' package instead.
      
      For further information please check the 'doc/src/install.rst' file (also at
      <https://www.psycopg.org/docs/install.html>).

当然，pip 是最新版本，我指定了 pip install psycopg2-binary。

我的 mac 的架构是 arm64。

如有任何帮助，我们将不胜感激。谢谢

Answer 1

psycopg2-binary 2.9.3 doesn't provide 适用于 MacOS arm64 的二进制轮；仅针对 Intel x86 64 位提供适用于 MacOS 的二进制轮。所以 pip 尝试从源代码编译 — 但失败了。

要从源代码进行编译，您需要大量 prerequisites。
