无法在 M1 Mac 上使用 pip3 安装 psycopg2

Question

我无法在 M1 Mac 上安装 psycopg2，我使用了 pip3。

当我尝试使用pip3 install psycopg2安装时，输出如下：

另外，我尝试使用以下源代码进行安装：

git 克隆https://github.com/psycopg/psycopg2.git
cd psycopg2
python3 setup.py 构建

它作为错误返回，如下所示：

running build
running build_py
running build_ext

Error: pg_config executable not found.

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>).

另外
python3 setup.py build 返回与“python3 setup.py build”相同的错误

我该如何安装？

Answer 1

在恢复任何旧的答案之前，我建议尝试以下操作：

brew install postgres然后使用安装 Postgres pip3 install psycopg2。

适用于 Mac M1、蒙特利、Python 3.9。

Answer 2

尝试这个：

brew install libpq --build-from-source
brew install openssl

export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib -L/opt/homebrew/opt/libpq/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include -I/opt/homebrew/opt/libpq/include"

pip3 install psycopg2

Answer 3

由于积极的开发，现在有新版本的 psycopg2 以及与 M1 设备兼容的 psycopg2-binary。版本。2.9.1 工作顺利。经过尝试和测试参考 - https://github.com/psycopg/psycopg2/issues/1200

Answer 4

您需要做的就是安装二进制文件：

pip install psycopg2-binary

从那以后一切都运行良好。我引用了此链接，直接跳到最后一步。如果第一次尝试安装二进制文件不起作用，我会看看本文中的其他步骤。
