Mac OS Sierra virtualenv(python 2.7)pip install mysqlclient错误

Question

在Mac OS Sierra上,使用python2.7创建virtualenv并尝试安装mysqlclient以使用Django w/MySQL.我通过自制程序安装了MySQL 5.6.运行"pip install mysqlclient"会出现以下错误:

Answer 1

答案是使用以下方法安装开发工具:

xcode-select --install

Answer 2

在我的情况下,我需要做两个步骤:

xcode-select --install

正如@howevilweare所说,并使用env命令使用brew安装的openssl进行pip安装:

env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install mysqlclient
