I have two solutions to this problem that I was able to find. 我有两个解决这个问题的方法,我能够找到。 I ran into this exact problem trying to install pygresql into a conda vitrual environment on OSX Sierra 10.12.5 and with the gcc installed from xcode-select --install.
我遇到了这个问题,试图将pygresql安装到OSX Sierra 10.12.5上的conda vitrual环境中,并从xcode-select --install安装gcc。 My solution for this (if others find this) was to use this command in the terminal:
我的解决方案(如果其他人发现这个)是在终端中使用此命令:
conda install gcc
This solved the problem for installing into the conda environment which you could use as a work-around. 这解决了安装到conda环境中的问题,您可以将其用作解决方法。 Install anaconda or miniconda then run these commands in the terminal:
安装anaconda或miniconda然后在终端中运行以下命令:
conda create -y python=3 --name my_env
source activate my_env
conda install -y gcc
pip install pygresql
I highly recommend using conda or virtualenv when doing development in python to avoid this types of issues. 我强烈建议在python中进行开发时使用conda或virtualenv来避免这类问题。
The more direct solution to your problem I found in this similar issue . 我在这个类似的问题中发现了更直接的问题解决方案。 I was able to solve pip installing directly into the OSX python (not the conda env) by running these commands in the terminal:
通过在终端中运行这些命令,我能够直接解决pip安装到OSX python(而不是conda env):
export CFLAGS="-Wno-error"
pip install PyGreSQL
