解决Python找不到ssl模块问题 No module named _ssl

转自：http://www.weidianyuedu.com/content/4011458198425.html

python安装完毕后，提示找不到ssl模块：

[www@pythontab.com ~]$ python
Python 2.7.15 (default, Oct 23 2018, 18:08:43)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.

import ssl
Traceback (most recent call last):
File “”, line 1, in
File “/usr/local/python27/lib/python2.7/ssl.py”, line 60, in
import _ssl # if we can’t import it, let the error propagate
ImportError: No module named _ssl

解决方法：

1. 查看openssl安装包，发现缺少openssl-devel包
   [www@pythontab.com ~]$ rpm -aq|grep openssl
   openssl-0.9.8e-20.el5
   openssl-0.9.8e-20.el5
   [www@pythontab.com ~]$
2. yum安装openssl-devel
   [www@pythontab.com ~]$ yum install openssl-devel -y
   #查看安装结果
   [www@pythontab.com ~]$ rpm -aq|grep openssl
   openssl-devel-1.0.1e-57.el6.x86_64
   openssl-1.0.1e-57.el6.x86_64
3. 重新编译python
   修改Setup文件

vi /src/Python-2.7.15/Modules/Setup
修改结果如下：

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
-L$(SSL)/lib -lssl -lcrypto

4. 重新编译
   进入源码目录，重新编译安装

[www@pythontab.com ~]$ cd /src/Python-2.7.15/
[www@pythontab.com ~]$ make
[www@pythontab.com ~]$ make install

5. 测试，已可正常使用。

[www@pythontab.com ~]$ python
