初识python 之 ImportError: No module named _ssl

场景

安装好python之后，导入ssl模块报错： ImportError: No module named _ssl

解决方法

查看openssl、openssl-devel是否安装

rpm -qa|grep openssl

openssl-devel-1.0.1e-30.el6.x86_64
openssl-1.0.1e-30.el6.x86_64

下载rpm包

安装

rpm -ivh openssl-devel-1.0.1e-30.el6.x86_64.rpm

注：按照提示安装依赖包

  或

    强制安装、忽略依赖关系

    rpm -ivh 包名 --force --nodeps

修改python文件

安装完rpm包之后，修改python文件

vi Modules/Setup.dist

#SSL=/usr/local/ssl
#_ssl _ssl.c 
#       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl 
#       -L$(SSL)/lib -lssl -lcrypto

修改为

SSL=/usr/local/
_ssl _ssl.c 
       -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl 
       -L$(SSL)/lib -lssl -lcrypto

重新安装python

./configure --prefix=/usr/local/
make
make install

运行

运行测试，正常。
