Python 3.7 psycopg2-Xcode错误“错误：命令'gcc'失败，退出状态为1”

Question

对于我目前正在使用Python / Kivy项目（使用PyCharm）进行的工作，我建立了一个postgreSQL数据库。当我尝试使用终端$ pip install psycopg2安装psycopg2适配器时，出现错误“错误：命令'gcc'失败，退出状态为1”。到目前为止，唯一有效的方法是从PyPI $ pip install psycopg2-binary安装Binary。对于在PyCharm中运行项目，它可以正常运行，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，该应用将崩溃，并显示错误没有名为'psycopg2'的模块（ main.py：导入psycopg2 ）。因此，我必须找到一种安装psycopg2的方法。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来解决此问题（还有更多方法，但是这些链接确实提供了我可以找到的主要方法）：

• 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
• error: command 'gcc' failed with exit status 1 while installing eventlet
• error: command 'gcc' failed with exit status when installing psycopg2

我正在使用：macOS Catalina 10.15.2 / Python 3.7.5 / postgres（PostgreSQL）12.1

我对这一切都是新手，几乎没有想法。我想稍后再在Phone上运行该项目，因此仅使用psycopg2-binary将不是令人满意的解决方案。谢谢！

Answer 1

我在macOS Mojave 10.14.6（18G2022）上遇到了同样的问题。

我使用命令安装了gcc。export const setPhotos = (receivedPhotos) => { console.log(receivedPhotos) return{ type: 'SETPHOTOS', payload: receivedPhotos }; } 。

然后我在终端中输入以下内容：

brew install gcc

另外，在安装psycopg2时，我做了sudo rm -rf /Library/Developer/CommandLineTools xcode-select --install cd /Library/Developer/CommandLineTools/Packages/ open macOS_SDK_headers_for_macOS_10.14.pkg ，否则，它是为Python 2.7.x安装的。 （Source）
