场景

刚配置的linux系统，安装完python3.7.9后使用requests模块，抛出异常：

Traceback (most recent call last):
  File "/usr/local/python3/lib/python3.7/site-packages/urllib3/connectionpool.py", line 659, in urlopen
    conn = self._get_conn(timeout=pool_timeout)
  File "/usr/local/python3/lib/python3.7/site-packages/urllib3/connectionpool.py", line 279, in _get_conn
    return conn or self._new_conn()
  File "/usr/local/python3/lib/python3.7/site-packages/urllib3/connectionpool.py", line 948, in _new_conn
    "Can't connect to HTTPS URL because the SSL module is not available."

During handling of the above exception, another exception occurred:

尝试方案

1. 更新spacy(地址：https://blog.csdn.net/zcyzhangzhou/article/details/86572845)：失败
2. 更新openssl(地址：http://www.45fan.com/article.php?aid=19073158040128417480594681)：失败
3. 安装requests的依赖包(地址：https://www.cnblogs.com/hum0ro/p/9536033.html)：失败

解决方案

因为python安装的时候可能没有安装openssl相关的开发包，因此需要手动安装：
yum install openssl-devel
安装好后重新编译一遍python或者删除重装
