解决解决Python找不到找不到ssl模块问题模块问题 No module named _ssl的方的方
法法
python安装完毕后，提示找不到安装完毕后，提示找不到ssl模块：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

>>> import ssl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/python27/lib/python2.7/ssl.py", line 60, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: No module named _ssl
>>>
解决方法：解决方法：
1. 查看查看openssl安装包，发现缺少安装包，发现缺少openssl-devel包包
[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。测试，已可正常使用。
