我可以在 macOS Monterey 终端中运行此命令，但在 PyCharm 中无法运行，我应该怎么做才能使其在 PyCharm 终端中运行？我已经尝试重新启动 PyCharm。我错过了什么吗？ PyCharm 终端和 macOS 终端有什么不同？

【解决方案1】：

我尝试在 PyCharm 终端中导出 LIBRARY_PATH，如下所示：

export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/Cellar/openssl@3/3.0.1/lib

作品。

【解决方案2】：

我尝试安装psycopg2-binary==2.9.3，但它不起作用。

@Dolphin 回答帮助了我，但我需要将版本从 3.0.1 更改为 3.0.5

我在终端中的命令

export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/Cellar/openssl@3/3.0.5/lib

pip install psycopg2-binary==2.9.3
