我的情况是
pipenv install mysqlclient
时候报错
An error occurred while installing mysqlclient==1.3.13!
...
...
...
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'clang' failed with exit status 1
...
...

但是似乎
pip install mysqlclient
也会遇到同样的问题
经过很久的搜索终于找到了解决方案
在~/.bashrc 或者 ~/.zshrc 里面添加环境变量
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
export PATH="/usr/local/opt/openssl/bin:$PATH"
export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"
然后source .bashrc
