Python安装pycurl失败的解决方法

Centos安装pycurl

centos 安装pycurl
yum install python-devel curl-devel
pip3 install pycurl

Mac(老版本)安装pycurl

解决MacOS升级后出现xcrun: error: invalid active developer path, missing xcrun的问题

xcode-select --install
然后
dongchang-5:qqmusic baoshan$ pip3 install pycurl
Collecting pycurl
 Using cached pycurl-7.43.0.1.tar.gz

ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)
解决办法
# pip uninstall pycurl
# export PYCURL_SSL_LIBRARY=openssl
# pip install pycurl

新版本Mac安装pycurl

但是这里有一个坑：在高版本的mac系统环境变量里是找不到openssl的头文件的
因为新版本Mac的openssl版本 LibreSSL 2.2.7

pip3 uninstall pycurl# 卸载库
export PYCURL_SSL_LIBRARY=openssl
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include# openssl相关头文件路径
pip3 install pycurl --compile --no-cache-dir # 重新编译安装

至此终于搞定。
