Python3.7无法正常导入ssl--ImportError: No module named _ssl

1.说明

在升级到python3.7后，发现pip无法正常安装模块，报错信息如下：

>>> import ssl
Traceback (most recent call last):
File "", line 1, in 
File "/usr/local/python37/lib/python3.7/ssl.py", line 60, in 
import _ssl # if we can't import it, let the error propagate
ImportError: No module named _ssl

2.解决方法

2.1修改Setup.dist文件

[root@storage2 ~]# vi /root/Python-3.7.1/Modules/Setup.dist

2.2修改结果如下：

将下面原本注释掉的内容给取消注释即可，一共四行
# Socket module helper for socket(2)
_socket socketmodule.c timemodule.c

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c /
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl /

2.3重新编译安装

[root@storage2 Python-3.7.1]#./configure --prefix=/usr/local/python37
[root@storage2 Python-3.7.1]#make
[root@storage2 Python-3.7.1]#make install
