无法在 MacOS 上通过 pip install 安装 psycopg2 包 [英] Can't install psycopg2 package through pip install on MacOS

问题描述

我正在为我的一个讲座开展一个项目，我需要下载包 psycopg2 才能使用正在使用的 postgresql 数据库.不幸的是，当我尝试 pip install psycopg2 时，会弹出以下错误:

I am working on a project for one of my lectures and I need to download the package psycopg2 in order to work with the postgresql database in use. Unfortunately, when I try to pip install psycopg2 the following error pops up:

ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit status 1
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command '/usr/bin/clang' failed with exit status 1

有谁知道为什么会这样?提前致谢！

Does anyone know why this is happening? Thanks in advance!

推荐答案

我通过安装命令行工具解决了这个问题

I fixed this by installing Command Line Tools

xcode-select --install

然后通过 Homebrew 安装 openssl 并手动将我的 homebrew 安装的 openssl 链接到 pip:

then installing openssl via Homebrew and manually linking my homebrew-installed openssl to pip:

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2
