python错误ImportError: No module named _ssl(centos下)

python错误ImportError: No module named _ssl(centos下)

场景

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

解决办法

1.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

https://archive.kernel.org/centos-vault/6.6/os/x86_64/Packages/

或

提取码：nce2

openssl-devel-1.0.1e-30.el6.x86_64.rpm
zlib-devel-1.2.3-29.el6.x86_64.rpm
openssl-1.0.1e-30.el6.x86_64.rpm
krb5-devel-1.10.3-33.el6.x86_64.rpm
krb5-libs-1.10.3-33.el6.x86_64.rpm
keyutils-libs-devel-1.4-4.el6.x86_64.rpm
libcom_err-devel-1.41.12-18.el6.x86_64.rpm
libselinux-devel-2.0.94-5.3.el6_4.1.x86_64.rpm
pkgconfig-0.23-9.1.el6.x86_64.rpm
libsepol-devel-2.0.41-4.el6.x86_64.rpm

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

1.下载python源码包

wget https://registry.npmmirror.com/-/binary/python/3.6.8/Python-3.6.8.tgz

2.解压

tar -zxvf Python-3.6.8.tgz

3.修改文件

cd Python-3.6.8/

vim Modules/Setup.dist

如果没有Setup.dist文件则修改Setup

原文件内容：大概在 51% 的位置

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

修改为：把注释去了，修改SSL的路径

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

4.重新安装python

在Python-3.6.8文件夹中输入命令：

./configure --prefix=/usr/local/python3

make

make install

运行

运行测试，正常。
