我做了一个简单pip install psycopg2的mac系统.它安装正常,但当我尝试使用psycopg2时,我收到错误:

Reason: Incompatible library version: _psycopg.so requires version 1.0.0 or later, but libssl.0.9.8.dylib provides version 0.9.8

pip freeze显示psycopg2==2.4.5恰到好处.我已经在几个virtualenvs上安装了psycopg2,但这是我第一次看到这样的错误.我尝试卸载并重新安装,结果相同.请帮忙

我在 OSX 中安装 psycopg2 时遇到了很大的麻烦。使用自制软件安装 Postgresql 9.5.4_1 后，我尝试在我的虚拟环境中安装 psycopg2： pip install psycopg2

我还使用 pg_config 添加到我的路径中 PATH=$PATH:/usr/local/Cellar/postgresql/9.5.4_1/bin/pg_config

执行后，我收到许多错误，包括：

  ld: library not found for -lssl


 clang: error: linker command failed with exit code 1 (use -v to see invocation)
  error: command 'clang' failed with exit status 1

和

Failed building wheel for psycopg2

和

尝试从源代码构建会导致类似的错误...

以前的研究和尝试的解决方案： …

尝试在MacOS 10.14.4上使用pip 19.1安装psycopg2会返回以下冗长的错误消息。我知道有些警告与gcc有关，但是鉴于实际的错误消息，我无法找到任何潜在问题的线索。

我尝试了以下操作，但没有任何运气：

• 将Xcode升级到最新版本（10.2.1）
• 将Postgresql升级到11.2.1
• 卸载psycopg2-binary以防止出现任何依赖性问题
• 清除了以前成功安装的所有文件/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages（是，我已经安装了某个文件，并且可以正常工作，不确定为什么要卸载）

在pip和psycopg2周围似乎存在很多问题，但是我在Stackoverflow上发现的任何问题都没有显示类似的错误消息，也没有提供任何建议的修复程序。非常感谢任何指向潜在修复程序的提示！
