centos7中python3.6报错ModuleNotFoundError: No module named '_ssl' 或者 Max retries exceeded with url: / (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.",))

如果在运行爬虫时报此错：requests.exceptions.SSLError: HTTPSConnectionPool(host='www.baidu.com', port=443): Max retries exceeded with url: / (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.",))并且在python命令行中引用import ssl ，报错ModuleNotFoundError: No module named '_ssl'采用以下方法：

解决方法：
步骤：
1、安装依赖：yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc gcc-c++ openssl-devel

2、修改python配置文件，并重新编译安装：
（1）vi Setup.dist

 

 

修改内容：如下图红线内内容全部将“#”去掉，谨记

 

 （2）重新编译安装Python3

 

 然后：

make ## 编译
make install 安装

3、测试：此时import ssl不报错
