Python安装pycurl失败，及解决办法

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-:qqmusic baoshan$ pip3 install pycurl

Collecting pycurl

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

>>> import pycurl

Traceback (most recent call last):

  File "<stdin>", line , in <module>

ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)

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。
