对于我目前正在处理的 Python/Kivy 项目（使用 PyCharm），我设置了一个 postgreSQL 数据库。当我尝试使用终端安装 psycopg2 适配器时，$ pip install psycopg2我收到错误“错误：命令'gcc'失败，退出状态为 1”。到目前为止唯一有效的是从 PyPI 安装二进制文件$ pip install psycopg2-binary。为了在 PyCharm 中运行项目，它工作正常，因为我可以将 psycopg2 和 psycopg2-binary 添加到我的解释器中。但是，当我现在尝试在 Xcode 中运行该项目并尝试使其在 iPhone 模拟器上运行时，该应用程序将崩溃并出现错误no module named 'psycopg2' ( main.py: import psycopg2 )。所以我必须找到一种方法来安装 psycopg2。使用来自 github 的源代码：
$ python setup.py build
$ python setup.py install
没有解决问题 - 仍然面临“gcc”问题。

ERROR: Failed building wheel for psycopg2
我尝试使用几种方法（以及更多方法，但这些链接确实提供了我能找到的主要方法）来解决这个问题：
- http://initd.org/psycopg/docs/install.html#install-from-source
- https://github.com/psycopg/psycopg2/issues/903
- https://github.com/stan-dev/pystan/issues/470
- 错误：安装 eventlet 时命令“gcc”失败，退出状态为 1
- 错误：安装 psycopg2 时命令“gcc”失败，退出状态
我正在使用：macOS Catalina 10.15.2 / Python 3.7.5 / postgres (PostgreSQL) 12.1
我对这一切都很陌生，几乎没有想法。我想稍后在我的手机上运行该项目，因此仅使用 psycopg2-binary 不会是令人满意的解决方案。谢谢！
