python安装 pycurl

操作系统：CentOS7.6 64位
Python版本：3.6.8
安装pycurl的时候报错

即无法查到"curl-config"这个文件，网上查下发现是因为CentOS自带的curl版本过低，下载安装更新高版本curl库。

wget https://curl.haxx.se/download/curl-7.68.0.tar.gz
tar -zxf curl-7.68.0.tar.gz
cd curl-7.68.0
./configure
make && make installvi /etc/profile.d/curl.sh
export PATH=$PATH:/usr/local/curl/bin/source /etc/profile

测试：curl -V

删除原来的libcurl库软链接,并新建链接
