把openssl从brew的应用包目录里复制到 /usr/local/lib/
brew update && brew upgrade && brew install openssl
cd /usr/local/Cellar/openssl/1.0.2t/lib
sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/local/lib/
cd /usr/local/lib
sudo ln -s libssl.1.0.0.dylib libssl.dylib
sudo ln -s libcrypto.1.0.0.dylib libcrypto.dylib然后重新执行pip3 list，不会再报错
