我无法在我的 M1 Mac 上安装 psycopg2，并且我使用了 pip3。
当我尝试使用 pip3 install psycopg2 安装时，输出如下：

另外，我尝试使用源代码安装：
git克隆https://github.com/psycopg/psycopg2.git
cd psycopg2
python3 setup.py build
它返回这样的错误：
running build
running build_py
running build_ext
Error: pg_config executable not found.

还有
python3 setup.py 构建
返回与
python3 setup.py build如何安装？
试试这个：
brew install libpq --build-from-source
brew install openssl
export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib -L/opt/homebrew/opt/libpq/lib"
export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include -I/opt/homebrew/opt/libpq/include"
pip3 install psycopg2
在恢复任何旧的答案之前，我建议尝试以下操作：
使用
brew install postgrespip3 install psycopg2适用于 Mac M1、蒙特利、Python 3.9。
感谢Kori Vernon。
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
按照以下步骤解决了我的问题：
❯ brew install postgresql@14
# If you open a new terminal tab you will see that pg_config is available
❯ export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include"
❯ export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib -L${HOME}/.pyenv/versions/3.10.7/lib" # use your current python version
❯ python -V
Python 3.10.7 # make sure it matches the same above configuration
❯ pip install psycopg2-binary==2.8.5
您所需要做的就是安装二进制文件：
pip install psycopg2-binary
从那以后一切都运行良好。我引用了此链接，然后直接跳到最后一步。如果安装二进制文件在第一次尝试时不起作用，我会看看本文中的其他步骤。
brew 安装 openssl
检查安装了哪个版本的 openssl！
导出 CPPFLAGS="-I/opt/homebrew/opt/openssl@{YOUR_OPENSSL_VERSION}/include"
python-V
导出 LDFLAGS="-L/opt/homebrew/opt/openssl@{YOUR_OPENSSL_VERSION}/lib -L${HOME}/.pyenv/versions/{YOUR_PYTHON_VERSION}/lib"
pip 安装 psycopg2-binary
适用于 Mac m1
