New version Mac installs pycurl

 But there is 1 A pit: in the higher version mac Not in the system environment variable openssl Of the header file 
 Because the new version Mac the openssl version  LibreSSL 2.2.7

pip3 uninstall pycurl#  Uninstall the library 
export PYCURL_SSL_LIBRARY=openssl
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include# openssl The associated header file path 
pip3 install pycurl --compile --no-cache-dir #  Recompile installation 

 So that's it.
