在安装了 PostgreSQL 12.1 的 MacOS catalina 上的 virtualenv 中安装 psycopg2 是否有任何问题?

Is there any problem installing psycopg2 in virtualenv on MacOS catalina with PostgreSQL 12.1 installed?

  ERROR: Failed building wheel for psycopg2
  Running setup.py clean for psycopg2
Failed to build psycopg2

我在使用 pip 在 vi​​rtualenv 上的 macOS Catalina 中安装 psycopg2 时遇到此错误。

我已经安装了 PostgreSQL 12.1 this link and also created some database on it following this link

所以有人知道 psycopg2 没有安装有什么问题吗?

您似乎没有安装 OpenSSL 库或其头文件。

我用 pip install Django psycopg2 而不是 pip install psycopg2 并且它起作用了。

我遇到了同样的问题 ld: library not found for -lssl

但我安装了 openSSL。对我来说,这相当于在 运行 pip install 之前根据 https://github.com/brianmario/mysql2/issues/795#issuecomment-337006164

设置以下内容
