mysql - 在 Mac OS 上安装 mysqlclient 时出错

Question

我正在尝试在 Mac OSX 上安装 mysqlclient，因为 Django 需要使用 MySql 而不是 sqlite DB。

我最初尝试过 pip3 install mysqlclient 但我遇到了这样的错误:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/3f/1z_bg4h52lz8n0_gc1mp7gwh0000gn/T/pip-install-em4vq6dr/mysqlclient/

我已经进行了大量的谷歌搜索并尝试了很多建议(这似乎是一个常见问题)，现在我得到了更多的错误消息:

有人对我哪里出错有任何建议吗？

使用 Python 3.6

谢谢

Answer 1

已根据这篇文章修复它 - https://github.com/PyMySQL/mysqlclient-python/issues/169#issuecomment-306821834 - 但我只做了这一点:

运行 brew info openssl

将以下内容作为两个单独的命令输入

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

然后:

pip3 install mysqlclient
