Python 3.7 psycopg2-Xcode错误“错误：命令'gcc'失败，退出状态为1”； [英] Python 3.7 psycopg2 - Xcode Error "error: command 'gcc' failed with exit status 1"
本文介绍了Python 3.7 psycopg2-Xcode错误“错误：命令'gcc'失败，退出状态为1”；的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
对于当前我正在处理的Python / Kivy项目（使用PyCharm），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：
For a Python/ Kivy project I'm working on at the moment (using PyCharm), I set up a postgreSQL database. When I try to install the psycopg2 adapter using the terminal $ pip install psycopg2 I am getting the error "error: command 'gcc' failed with exit status 1". The only thing that worked so far was installing the Binary from PyPI $ pip install psycopg2-binary. For running the project in PyCharm it works fine, since I could add psycopg2 and psycopg2-binary to my interpreter. But when I now try to run the project in Xcode and try to make it work on the iPhone simulator, the app will crash with the error no module named 'psycopg2' (main.py: import psycopg2). So I'll have to find a way to install psycopg2. Using the source code from github:
$ python setup.py build
$ python setup.py install
没有解决问题-仍然面临'gcc'问题。
did not fix the problem - still facing the 'gcc' problem.

的修轮失败我尝试使用以下几种方法解决此问题方法（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）：
I tried to fix the issue using several approaches (and some more, but these links do provide the main approaches I could find):
- http://initd.org/psycopg/docs/install.html#install-from-source
- 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，退出状态为

- 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
I am using: 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！
I am very new to all of this and run out of ideas pretty much. I want to run the project on my Phone later, so just using psycopg2-binary will not be the satisfying solution. Thank you!
推荐答案
我在macOS Mojave 10.14.6（18G2022）上遇到了同样的问题。
I had the same problem on macOS Mojave 10.14.6 (18G2022).
我使用以下命令安装了gcc。 brew install gcc 。
I installed gcc using the command.brew install gcc.
然后输入在终端中输入以下内容：
I then typed the following in Terminal:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg

另外，在安装psycopg2时，我做了 pip3安装psycopg2 ，否则，它是为Python 2.7.x安装的。 （源）
Also when installing psycopg2, I did pip3 install psycopg2, otherwise, it was installing it for Python 2.7.x. (Source)
